| 1. Improve the setmenu string function, add index and centering in the menu area. Strings can use background colors. | |
| setmenu --string[=iINDEX]=[X|s|m]=[-]Y=COLOR="STRING" | |
| The range of iINDEX is i0-i15. If there is no =iINDEX, the index is automatically incremented. | |
| If the horizontal position is s, the string is centered in the full screen; if the horizontal position is m, the string is centered in the menu area. | |
| 2. Dynamically update the date and time and add a title, which can display Chinese. | |
| For example: "date&time date time: =MMM.dd.yyyy HH:mm:ss" | |
| 2019-10-27(yaya) | |

| Improved graphics menu: supports background highlighting and mixed graphics and text. | |
| setmenu --graphic-entry=Graphic type=Number of graphic menu rows=Number of graphic menu columns=Graphic width=Graphic height=Graphic line gap graphic file | |
| When graphics and text are mixed, the settings for graphics and text selections (highlighted items) are independent and can be set independently. | |
| If highlighting only needs to be achieved through text, the graphics type can be set to 0x90. | |
| Graphic type: | |
| Bit 0: Foreground highlight Bit 1: Flip foreground color Bit 2: Graphic frame Bit 3: Background highlight Bit 4: Mixed graphics and text Bit 7: Transparent background | |
| The graphics line gap is in the mixed graphics and text mode and cannot be adjusted at will. If the gap is not ideal, you can set the graphics gap to zero. Then use increased character spacing to achieve this. (setmenu --font-spacing=0:n) | |
| 2018-12-23(yaya) | |
| Fixed the problem of no alarm when reading disk out of bounds. | |

| 3. Modify grub_memmove function to improve operation speed. | |
| 4. Fixed the fragment mapping error in the map function. | |
| 2018-04-23(yaya) | |
| Add !BAT in the first line of the menu item to write and execute in batch processing mode, using the batch processing function. For example: goto :label | |
| The difference in writing is the use of the escape character %. | |
| In the original menu item: | |
| set a2=%@root:~0,-2%0) | |
| set srs=%SRS0PE%%srs% | |
| Writing menu items in batch mode: | |
| !BAT | |
| set a2=%@root:~0,-2%%0) | |
| set srs=%SRS0PE%%%srs% | |
| Revoke the modification instructions of 2018-04-08 and 2018-02-20. | |

| The high byte is the partition ID, specified using 0xnnnn. | |
| 2018-03-24(yaya) | |
| Function read adds --8 parameter and reads 8 bytes at a time. | |
| 2018-03-15(yaya) | |
| Enhance setmenu --string function function | |
| --string=[X]=[-]Y=COLOR="STRING" | |
| Without X, it means horizontal centering. | |
| -Y means counting from the bottom of the menu. -0 is the last line. | |
| 2017-12-05(yaya) | |
| Enhanced color assignment function. Corrected color and echo help information. | |
| 1. Assign colors according to the target, and the order cannot be disordered (unselected menu, selected menu help title). The color can be replaced with the placeholder n. | |
| Example: color black/cyan yellow/cyan red/cyan light-green/cyan character color/background color, use symbol color. | |
| Example: color 0x30 0x3e 0x34 0x3a High-bit background color, low-bit character color, 8-digit number. | |
| Example: color 0x888800000000 0x888800ffff00 0x888800880000 0x88880000ff00 64-bit number. | |
| Example: color 0x30 and the rest are the same as NORMAL. Used on the command line to change the console color. | |
| Example: color 0x30 0xe n 0xa The background color is taken from NORMAL. Use placeholder n. | |
| 2. You can assign a color to the specified target, NORMAL should be in the first place. | |
| Example: color normal=0x888800000000 The other target colors are the same as NORMAL. | |
| Example: color normal=0x4444440000ffff helptext=0xc highlight=0xd heading=0xe border=0xa The background color is the same as NORMAL. | |
| Example: color standard=0xFFFFFF changes the console color. | |
| 3. Change the color of the string | |
| Example: echo $[0xCD] string changes the color of the string (8 or 64 bits). C=Background color, D=Character color. | |
| Example: echo $[] string string uses system standard colors. | |
| 4. The specific color can be viewed on the command line. | |
| Example: echo -h-rrggbb | |
| Example: echo -rrggbb | |
| 2017-11-28(yaya) | |
| Modify the setmenu function and add the following parameters: | |
| 1. --draw-box=[index]=[start x]=[start y]=[horizontal length]=[vertical length]=[line width]=[color] | |

| uuid [--write] [DEVICE] [UUID] | |
| Example: vol displays the volume labels of all devices. Including floppy disks, hard disks, CDs and image files. | |
| vol DEVICE displays the volume label of the specified device. | |
| vol VOLUME searches for the device with the specified volume label and sets it as the root device. | |
| vol DEVICE VOLUME Verifies the volume label of the specified device, returning true if the same. | |
| vol --write DEVICE VOLUME writes (modifies or creates) a volume label to the specified device. | |
| Note: The volume label can only be modified in FAT and NTFS file systems. Only single-character labels (such as English) can be written. | |
| 2017-04-21(yaya) | |

| setmenu --graphic-entry=type=number of menu lines=number of menu columns=graphic width (pixels)=graphic height (pixels)=menu line spacing (pixels) Path file name of menu item 0 | |
| Type: Bit 0: Highlight specified color Bit 1: Highlight color flip Bit 2: Highlight wireframe Bit 7: Transparent background (it is best to use a black background) | |
| File name: *n.??? Format n=00-99 | |
| The highlight color is specified by color HIGHLIGHT=0xrrggbb. | |
| Characters can use any font type, font height, and color, and can be supplemented by icons. | |
| 2016-03-25（yaya） | |
| Menu characters can use different fonts. | |
| For example: "Seven" uses different fonts, and changes the unicode code "4e03" in the .hex file to "0080". | |
| Change "seven" in the menu to "\X0080". | |
| 2016-03-23（yaya） | |
| Enhance the echo function function. | |
| For example: echo -e \x18 displays UTF-8 character 0x18. | |
| echo -e \X2191 displays the unicode character 0x2191. | |
| 2016-03-15（yaya） | |
| 1. Add animation control hotkey F2: play/stop. | |
| 2. Add animation control bit 0x835b, bit 0: 0/1=stop/play. | |
| 3. Add simplified font mode: --simp=start 0, end 0,..., start 3, end 3 | |
| You can use --simp= for Chinese, and the built-in font should include DotSize=[font_h],['simp'] | |
| For example: font --font-high=24 --simp= /24_24.hex | |
| DotSize=24,simp | |
| No hotkeys are used: 32*32 unifont full font library can be loaded | |
| Use hotkeys: can load 24*24 unifont full font library | |
| Use simplified font: can load 46*46 Chinese character full font | |
| Use simplified fonts and hotkeys: 40*40 Chinese character full fonts can be loaded | |
| 4. Bin format font is no longer supported. | |
| 2016-03-03（yaya） | |
| 1. Add image background color setting method. splashimage --fill-color=[0xrrggbb] | |
| One of its functions is as a background for small images. | |
| The second function is to directly serve as the background of the menu (that is, the image background is not loaded). At this time, you only need to set the foreground color of the font. | |
| 2. Add animation menu. splashimage --animated=[type]=[delay]=[last_num]=[x]=[y] START_FILE | |
| Type [type]: bit 0-3: play count bit 4: repeat forever bit 7: transparent background | |
| type=00: prohibit playback | |
| Play n times: Each sequence image is displayed n times, and the time is exclusive. It can be used as a prelude and prelude to the start-up. | |
| Repeat Forever: Sequence images loop infinitely and time is shared with the menu. Can be used as animation in menu. | |
| Transparent background: that is, keying. The four corner pixels are required to be the background color. | |
| The background color is preferably white or black to remove some gray clutter. If it's a colored background, it should be very clean. | |
| Reminder: Please enter in hexadecimal. Otherwise it is easy to make mistakes. | |
| Delay [delay]: Delay between sequence images. The unit is tick, which is 1/18.2 seconds. | |
| Sequence number [last_num]: Total number of sequence images (2 digits, counting from 1). | |
| Offset [x], [y]: Image offset, unit pixel. | |
| Start image file START_FILE naming rule: *n.??? n: 1-9 or 01-99 or 001-999. | |
| 3. Increase the background color of fixed images to be transparent. splashimage [--offset=[type]=[x]=[y]] FILE | |
| Type[type]: bit 7: transparent background | |
| 2016-02-14（yaya） | |
| The setmenu function adds menu item background short/full parameters (default short) | |
| 2016-01-19（yaya） | |
| The splashimage function increases the starting offset of the image (default 0) | |
| 2015-08-20（yaya） | |
| 1. Support non-16*16 fonts. | |
| Add parameters to the font function: | |
| --hex* --bin font output type; | |
| --horiz-scan* --verti-scan bitmap character scanning mode; | |
| --h-to-l* --l-to-h How dot matrix characters are stored in bytes; | |
| --font-high=[font_h] The height and width of bitmap characters (should be equal). | |
| Note: * is the default item. | |
| Example: font /my.hex | |
| font --bin --verti-scan --l-to-h --font-high=20 /2_20.dzk | |
| font --bin --font-high=20 /1_20.dzk | |
| Built-in font library, if it is not a 16*16 font, the header needs to be declared: DotSize=[font_h]. | |
| Due to memory limitations, the current large font can support up to 32*32, and the Chinese small font can support up to 40*40. | |
| 2.VGA graphics mode is no longer supported. | |
| 2015-07-07（yaya） | |
| 1.Supports 16-bit per pixel color mode (64K 5:6:5). | |
| 2. Support jpg (jpeg, jpe) image format. | |
| 3. In vbe mode, use echo -rrggbb to display 216 color samples. | |
| 4. Use echo -v to display version and memory information. | |
| 5. Add setmenu function to enhance the graphical menu editing function. parameter: | |
| --ver-on --ver-off Turn version information on/off. Open by default; | |
| --lang=en --lang=zh Switch the key help information between Chinese and English. Default English; | |
| --auto-num-off --auto-num-on Turn off/on automatic menu numbering. Off by default; | |
| --font-spacing=[font]:[line] Set character spacing/line spacing. Unit: pixel. Default is 0. Should be placed before the following parameters; | |
| --string=[x]=[y]=[color]=["string"] String position, color and content, which can be used for titles, descriptions, help, etc. Units: column, row, 24-bit color. | |
| Note: If the color is omitted, the title color will be used if it is located above the menu box, and the help text color will be used if it is located below the menu box; | |
| English double quotes must be added at the beginning and end of the string; | |
| Number of columns = image horizontal pixels/(character width + character spacing) character width = 8; | |
| Number of lines = image vertical pixels/(character height + line spacing) character height = 10; | |
| --box x=[x] y=[y] w=[w] h=[h] l=[l] Project title starting column, starting line, maximum number of characters per line, maximum number of menu items, menu Box line width (pixels); | |
| Note: w=0 means horizontal centering. At this time w should be after x; | |
| l=0 means not to display the menu box; | |
| --help=[x]=[w]=[y] Project help location. Unit: column, row. Default 1 line; | |
| Note: x=0 is determined by the border (default); w=0 is horizontally centered; | |
| --keyhelp=[y_offset]=[color] Key help position and color. Units: column, row, 24-bit color. | |
| Note: y_offset=0, the project and key help are located in the same area, and the project help can override the key help (default); | |
| y_offset !=0, is the line offset from key help to project help, both coexist; | |
| y_offset<=4, is the number of rows displayed in the project help; | |
| color defaults to "color helptext"; | |
| --u Restore the menu to its original state. | |
| --timeout=[x]=[y]=[color] Countdown position and color. Units: column, row, 24-bit color. | |
| 2015-05-14（yaya） | |
| Improve NTFS file system: | |

| 1.(tinybit) Workaround for BIOS of BENQ notebook that only supports 1. | |
| 2014-10-15 | |
| 1.workaround for issue 204(chenall) | |
| 2014-10-12 | |
| 1. The skip_to() function is modified. The "\" inside the quotation marks is processed using the previous method to maintain compatibility. (chenall) | |
| 2. add variable @boot, add debug info. (chenall) | |
| 3.two variables boot_drive and install_partition can be preset to a value before transferring control to grub4dos. (tinybit) | |
| 4. Correct the masking map information. (yaya) | |
| 2014-10-09（yaya） | |
| 1. Block map information. | |
| 2014-09-23（yaya） | |
| 1. Use bootlace.com to install grldr.mbr to a gpt partition type device. | |
| 2014-09-02（yaya） | |
| 1.ext4 partition supports 64-bit functions and metablock groups. | |
| 2.grldr header and grldr.mbr support searching grldr of gpt partition. | |
| 3. Fixed bootlace. | |
| 2014-08-17 | |
| 1. Fixed the bug of GPT unhide/hide, now the gpt partition can be hidden normally. | |
| 2. Optimize the GPT partition search code. | |
| 3. Allow direct access to GPT reserved areas, but do not display them in the list. | |
| 2014-08-01(no click) | |
| 1. Solved the problem that the partition with partition ID 00 reported by reboot.pro cannot be recognized and cannot be accessed. | |
| 2. Solved the problem that chainloader --raw cannot load the boot sector of hard disk BPB hidden sectors=0. It was also reported on the English forum. | |
| 3. Clear the residual information after ud startup so that subsequent startups will no longer be repeatedly recognized as ud startups (because subsequent startups will no longer start from ud). | |
| (yaya) | |
| 1. Make the default_func and geometry_func codes in builtins.c consistent with 0.4.5c. | |
| 2. Make the code in common.c and stage2.c consistent with 0.4.5c (except for the intentional changes in 0.4.6a). | |
| 2014-07-9(yaya) | |
| Fixed floppy disk search. | |
| Supports 16-slot mapping. | |
| 2014-06-23(yaya) | |
| 1. Improved the simulation of fragmented files. Maximum of 32 fragments. If all use the new version, fragmented information can be transmitted. | |
| 2. The ntfs file system supports non-resident attribute lists within 8Kb. | |
| 3. Fixed the udf format CD driver bug. | |
| 4. Fixed the iso9600_Joliet file format escape character display problem. | |
| 2014-01-16(yaya) | |
| 1. When the U disk in FDD mode (with BPB and no partition table) is assigned the drive letter 0x80 by the BIOS, it is mapped to 0x00. | |
| At the same time, shield the drive number 0x80 (to avoid reading the USB disk through the BIOS, which may cause a crash). | |
| This change also avoids the problem of Issue 162 reading 64-bit logical sectors. | |
| The USB disk in FDD mode is recognized as a hard disk, which causes many problems. The problem that has been discovered is that (hd0) is not returned when executing find; the streamlined PE crashes when loading the image file. | |
| 2. Solved the problem of U disk in FDD mode returning (fd0,n) when executing find. | |
| 3. Corrected the default location of 0PE.ISO in menu.lst. | |
| 4. The usb2.0 driver can be loaded through the menu or command line using usb --init. | |
| 5.usb2.0 driver adds support for hub (HUB). If loading fails, you can try restarting. | |
| 6. When reading multiple sectors fails, a prompt will be given: unplug the USB flash drive and then insert it again, press any key to continue. At this time, the USB disk will be re-initialized. | |
| And continue from the failure point by reading 1 sector at a time. | |
| 7. Enhance file name recognition to facilitate renaming. | |
| 7.1 File names can be in any case, but must be in uppercase letters in grldr.mbr and grldr.pbr. | |
| 7.2 In grldr.pbr: | |
| FAT16 and FAT32 partitions use 8.3 format; | |
| ext2, exFAT, and NTFS partitions use 12 characters. | |
| 7.3 In grldr.mbr: use 12 characters. | |
| 7.4 In order to be compatible with various partitions, it is recommended that the file name should not be larger than 8 characters and the suffix should not be larger than 3 characters. If there is a separator ".", it cannot be omitted. | |
| 2014-04-01(yaya) | |
| 1. Updated USB2.0 driver device enumeration. Improved drive letter recognition. Run directly from the current location, the cache is moved to 0x80000. Resident memory is reduced to 4 Kb. | |
| 2. Supports fragmented file emulation, up to 8 fragments. Occupies 11Kb - 13Kb of memory (determined by whether the optical drive is loaded). | |
| 3. Support lowercase short file names in WinXP system. According to the offset 0x0c of the short file name: bit 3=1 means the file name is lowercase, and bit 4=1 means the file extension is lowercase. | |
| 4. Can correctly identify the buggy Joliet format CD generated by mkisofs 2.00/2.01. | |
| 2013-10-18 | |
| 1. The new function is similar to CMD's PATHEXT, which can set the default extension. | |
| Use command --set-ext to set, and separate each extension with ";" | |
| example: | |
| command --set-ext=.g4b;.g4e | |
| You do not need to enter the extension when executing. For example, if you enter test, if there is a test.g4b in the current path, it will be used automatically. | |
| 2013-10-17 | |
| 1. Modify the code to support the new version of HOTKEY. | |
| 2013-07-10 | |
| 1.insmod now supports long file names (previously up to 11 characters, now no limit). | |
| 2. Modify some codes to solve the problem and eliminate the "Warning" information during compilation. | |
| 2013-06-30 | |
| 1. Solve the memory conflict problem caused when the command line length is too long or there are too many batch parameters. | |
| 2013-03-19 | |
| 1. Added the continuous command separator ";;" to prevent sequential execution. | |
| example: | |
| set a=abcd ;; echo %a% ;; set a= | |
| 2013-03-02 | |
| 1. Solve Issue 117: menu border has arrow symbol (bottom right) | |
| 2. Allow other display modes to also specify the menu box color. color border=xx | |

| 1. Fixed the bug that grub_sprintf function %d cannot display negative numbers correctly. | |
| 2011-12-12 command 'if' added '>=' and '<=', and able to perform numeric comparison. | |
| 1. The if command adds >= and <= comparison operators. | |
| The new if command supports three comparisons >=,==,<= | |
| If both sides are numbers, they will be automatically converted into numerical values for comparison, otherwise they will be compared according to the ASCII size of the strings. | |
| 2011-12-11 | |
| 1. You can use map --status=n to obtain the status of the mapped disk. use map --status=n to get status of hooked drive n. | |
| Return the following two variable information (return) | |
| %?%=Start_Sector | |
| %@retval%=Sector_Count | |
| Returns 0 if the disk does not exist. | |
| 2011-12-08 | |
| 1. Support automatic menu numbering (more useful when using dynamic menus). Support menu AutoNumber.this is useful when used iftitle. | |
| usage: | |
| write 0x8274 0x2001 | |
| or | |
| write 0x8274 0x2D01 | |
| 0x20(space) or 0x2d ('-') is the delimiter char in ascii code. | |
| More usage introduction: | |

| 2011-12-06 | |
| 1. Bug fixes. | |
| 2. When starting in debug mode, the commands executed by the conditional menu can be displayed. | |
| 2011-12-05 | |
| 1.Add conditional menu function added iftitle. | |
| Syntax: iftitle [] Actual Title displayed\nOptional help line | |
| This menu item is invalid as long as the condition is not met. | |
| eg. The first menu will be displayed only if there is a bootmgr file on (hd0,0), and the second menu will be displayed only if there is an NTLDR file. | |
| iftitle [if exist (hd0,0)/bootmgr] Boot to NT6.X from (hd0,0) | |
| chainloader (hd0,0)/bootmgr | |
| iftitle [if exist (hd0,0)/ntldr] Boot to NT5.X from (hd0,0) | |
| chainloader (hd0,0)/ntldr | |
| 2011-12-01 | |
| 1.BUG fixed. | |
| BUG fixed. | |
| 2. Add the function of using INT18 to start. | |
| Supported boot via INT 18. | |
| Usage: | |
| boot -1 | |
| or | |
| boot --int18 | |
| 3. Some code streamlining | |
| 2011-11-29 | |
| 1.BUG fixed. | |
| 2. New color command syntax. | |
| color color_state=color [..] | |
| The color_state string can be as follows. | |
| normal unchecked menu | |
| highlight select menu | |
| helptext menu help information | |
| heading menu header (GRUB4DOS information) | |
| standard default color (console) | |
| border menu border is effective in VBE mode | |
| 3. New setcolor/setcolorstate function | |
| 2011-11-27 | |
| 1. Fixed the problem that the background image color would be wrong when the fontfile command is behind splashimage. | |
| 2. In VGA mode (0x12/0x6a), when the splashimage command is not used, the font color can be specified to be the same as in console mode. | |
| 2011-11-22 | |
| 1. The new COLOR command allows setting the default font color and background color of the console (limited to text mode or VBE mode) | |
| Method: Just use the color command with only one parameter. | |
| Note: Valid when executed from the command line or batch script. | |
| 2011-11-19 | |
| 1.cursor_state bit 0=1 show cursor,bit 1=1 show splashimage. | |
| use setcursor(n) to change if need,can change from commandline eg | |
| call Fn.70 0 disable cursor and splashimage. | |
| 2. Clean up some useless code. | |
| 2011-11-18 | |
| 1. Supported splashimage with BMP format (VBE mode only). | |
| 2. When using BMP images, if you are not in VBE mode, try to automatically match the image resolution. | |

| 2. Ignore the case of file names on ISO9660 file systems. Make name comparisoncase-insensitive on iso9660. | |
| You can use below command to disable this feature. | |
| write 0x4CA24 0 | |
| 3.Add --locatei parameter to cat command, added --locatei option for cat. | |
| Ignore case ignore case locate. | |
| e.g. | |
| cat --locatei=Test (md)0x300+1 | |
| 2011-10-07 | |
| 1. Add the ?_BOOT variable to access the Boot_drive that starts GRUB4DOS | |
| add new Variable ?_BOOT to access grub4dos Boot_drive. | |
| 2. In order to save code, GRUB4DOS no longer handles the compatibility of external commands WENV internally (WENV tuxw version) | |
| The solution is as follows: | |
| If you need to use this version of WENV, add the following commands to the menu or batch process yourself | |
| write --offset=0x1f8 (md)0x228+1 ?_WENV\0 | |
| 3. The uuid command is not case sensitive when judging uuid characters. | |

| 注:1.将来会取消?_UUID,为了保持兼容性,暂时先放一段时间. | |
| 请使用%?%或%?_WENV%代替%?_UUID%来获取UUID. | |
| 2.%?%变量可以获取命令返回的字符串信息. | |
| 目前可用的信息有两个.uuid dev(返回指定设备的UUID字符串),cat --locate= (返回最后一个找到的位置) | |
| 2.@random算法修改. | |
| 2011-07-13 | |
| 1.在执行cmain之前初始化变量内存空间。 | |
| 2011-07-12 | |
| 1.执行clear命令时同时设置count_lines为0。 | |
| 2.内置变量增加@retval，其实就是之前的0x4cb00 | |
| 3.增加setlocal @和endlocal @用法。 | |
| setlocal @可以在批处理中使用,把当前的环境保存起来 | |
| 除非使用endlocal @否则setlocal @之后的设置会一直保留(批处理退出也不影响). | |
| 注：1.在批处理中出现setlocal @则在批处理中setlocal @之前的setlocal命令会全部失效。 | |
| 所以setlocal @有必要的使用的话一般要放在批处理最前面。 | |
| 2.setlocal @后面如果还有出现setlocal，则setlocal之后的设置不会保留. | |
| 2011-07-11 | |
| 1.添加SETLOCAL和ENDLOCAL命令，和WINDOWS下的批处理用法一样。 | |
| 2011-07-05 | |

| 3.消除一些编译时的警告信息。 | |
| 2011-05-23@174 | |
| 1.修正一个TFTP相对路径的问题，感谢2011exuejiao@wuyou. | |
| 2.在批处理中可以使用debug 3临时开启debug模式。 | |
| 2011-04-30@159 | |
| 1.取消前面版本对批处理参数的调整.恢复到04-16版. | |
| 2.修正一个BUG.(函数print_root_device). | |
| 3.批处理参数新增%~f 文件全路径,%~z文件大小. | |
| 4.现在批处理脚本可以使用使用errorcheck命令控制是否检测错误(默认错误就退出). | |
| 2011-04-29@157 | |
| 1.find 命令不再查找(hdx)设备. | |
| 2.删除@root变量的前导空格. | |
| 3.ls命令新增dev参数,用于显示设备列表. | |
| 4.批处理代码调整,对于(bd)设备%~d0会使用实际的设备. | |
| 2011-04-25@156 | |
| 1.新增两个内置变量@root,@path. | |
| @root 当前的root. | |
| @path 当前默认外部命令查找路径. | |
| 2.修正一个可能导致程序出错的问题.(使用到了临时变量的内存). | |
| 3.批处理代码功能增强. | |
| 2011-04-16@153 | |
| 1.md5crypt 支持参数。后面直接跟一个字符串会直接计算这个字符串的md5。 | |
| 2.菜单支持以变量开头的命令。 | |
| 2011-03-30@151 | |
| 1.LZMA格式解压时暂时禁止显示进度（因为显示进度时解压大文件会失败）。 | |
| 2.添加内置变量?_UUID（使用uuid命令可以把获取到的磁盘uuid保存到变量中）. | |
| 2011-03-29@150 | |
| 1.insmod *.mod添加了检测模块文件头是否为GRUBEXEC签名. | |
| 注：目前还是兼容旧版本的MOD模块，一段时间后会取消，请使用新的MAKEMOD重新制作模块。 | |
| 2.对批处理路径和文件名的空格进行自动处理。空格前面自动加转义符"\" | |
| 注：使用p,n,x参数时有效。即%~1时不会处理，但%~p1时会处理。 | |
| 2011-03-26@150 | |

| 说明:DEVICES可以是以下字符的组合: | |
| u,p,n,h,c,f -->分别对应 ud,pd,nd,hd,cd,fd, | |
| 例子:--devices=hcf //只查找hd,cd,fd,从hd开始. | |
| 注:优先current root.然后再按上面的顺序.(current root必须在列表中,否则跳过) | |
| 可以使用这个参数来重新设定查找顺序,默认(find order):ud->pd->nd->hd->cd->fd | |
| 4.保留--ignore-cd和--ignore-floppies参数(会自动转换). | |
| 2010-10-26 | |

| 有时候会需要这样的功能，比如执行某个菜单失败后返回菜单时重新执行一次初始化。 | |
| initscript /initscript.g4d | |
| 2010-09-25 | |
| 1.简易计算器调整.如果没有"="则不保存计算结果,但++和--除外. | |
| 例子: | |
| calc *0x60000 + 4 不保存计算结果,所以内存指向*0x60000的值不会被改变. | |
| calc *0x60000++ 会保存计算结果到*0x60000中. | |
| calc *0x60000 = 1+2 同上. | |
| 2.如果当前已经是图形模式允许graphicsmode直接切换,而不用经过terminal console中转. | |

| note: 1.use with "&&" and "||" ,the "|" and ">" must be at last. | |
| 2."|" and ">" can not use at same time. | |
| 例子: | |
| 1. pause abcd | pause efg | |
| output: efgabcd | |
| 2. pause 0x60000 | read #There is a space after the read. | |
| run read 0x60000 | |
| 3.help > (hd0,0)/help.txt or help > (md)0x3000+2 | |
| help.txt must already exist,grub4dos cann't create file or change file size. | |
| 2010-09-05 | |

| 2010-03-29 | |
| 1.外部命令执行过程调整。 | |
| 例子:默认path (bd)/grub/ | |
| echo abcd ## 优先使用(bd)/grub/echo 文件，如果没有再找 /echo 文件 | |
| /echo abcd ## 只查找/echo 文件。 | |
| (fd0)/echo abcd ## 只找 (fd0)/echo abcd 文件。 | |
| 2.find 命令添加一个 --ignore-oem 参数。 | |
| http://code.google.com/p/grub4dos-ireneuszp/ | |
