Disk /dev/sda: 783 cylinders, 255 heads, 63 sectors/track
Old situation:
Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0

Input in the following format; absent fields get a default value.
<start> <size> <type [E,S,L,X,hex]> <bootable [-,*]> <c,h,s> <c,h,s>
Usually you only need to specify <start> and <size> (and perhaps <type>).

Warning: partition 2 has size 0 but is not marked Empty
Warning: no primary partition is marked bootable (active)
This does not matter for LILO, but the DOS MBR will not boot this disk.
end of partition 2 has impossible value for cylinders: 1023 (should be in 0-782)
I don't like this - probably you should answer No
Do you want to write this to disk? [ynq] n
