Hey there tparikka,

Here is the "Cheat sheet" I created for interfacing with the LOM on my SunFire V100. The answer to your problems is probably here. If you still have questions, ask a more specific one based on these docs.

=== BEFORE INSTALLING SOLARIS ON A SUN FIRE (SPARC BASED SYSTEM) ===

- Serial Adapter and RJ45 Standard cable Required
- Use Serial Port on another computer and A LOM on Sunfire
- Important B Serial is used to communicate to another box

- Setup 9600 8N1 and use Minicom /dev/ttyS0
- Hit enter and you should just get in!!

NOTE: 3 Modes for interfacing with the SUNFIRE
There are 3 different kinds of modes to enter commands
1. LOM Mode -> LOM > (This is the prompt)
2. OpenBoot PROM mode -> ok (This is the prompt)
3. Unix Shell -> # (This is the prompt)

== SETUP USER IN LOM ==

NOTE: At ANY time in SOLARIS you can drop down to the LOM with the special keys "#."
NOTE: This applies ONLY when logged in via SERIAL PORT
NOTE: If logged in via LAN PORT, you can't drop down to the LOM

LOM> console -> To return to COMMAND PROMPT "#"

LOM> help -> Shows "Help" for LOM

= I am trying to boot off a CDROM to install Solaris 10 =

Console speed = 9600 8N1 -> Can't make it faster

LOM> set bootmode forth -> In order to control the boot process set the bootmode
LOM> show bootmode
LOM> reset

NOTE: I reviewed the LOM mode and there isn't much I can do here except set the "Bootmode"
NOTE: I did setup a USER: xxxxx PASS: xxxxx & gave FULL ACCESS

== OPENNBOOT PROM MODE ==

NOTE: once the "Bootmode" is set and the system is "reset" you get into "OpenBoot Prom" mode
NOTE: If no devices are being shown, then there is a problem!
SOLUTION: Unhook all devices, power down the system and Unhook the Power cord for 30 secs
CHECK: does this solve the problem? NO!

ok probe-all -> DO THIS FIRST! IMPORTANT!
ok probe-ide -> This shows all the IDE devices

= OTHER COMMANDS =
ok reset-all

ok boot cdrom -> Boot from CDROM
ok boot disk0:a -> Boot off Disk0 Slice A

NOTE: If CDROM is on another drive port, edit the command directly

boot-device disk0:a disk net disk net

= When you are ready to BOOT from a CDROM do this ==

ok setenv boot-device cdrom -> Set the boot device to CDROM
ok reset-all -> System will reboot and Load CDROM

= OTHER OPTIONAL COMMANDS =

ok setenv boot-device disk0:a disk net -> Set the boot device to CDROM (after OS install)

ok reset-all

NOTE: If you are at the ok prompt you can try and boot off the disk

ok boot disk

IDE Port Near PSU = Drive 0 Drive 1 (BOOT DRIVE EMPTY)
IDE Port Near RAM = Drive 2 Drive 3 (MIRROR DRIVE CDROM)

Detecting Drives is a little Finicky!!
- For the CDROM to get detected as a SLAVE (DRIVE 3) the system needs HD as Master (Drive 2)
- Otherwise setup CDROM as a Master with it's jumper
- Further, the alias is wrong, you need to edit it a bit to boot from the correct device

= PROBLEM Booting =
Note: everytime I boot the system tries to boot off the NET
Note: need to change this to booting off the disk

ok setenv auto-boot? true -> Command to auto-boot
ok setenv diag-switch? false -> Command to take diagnostics OFF!
ok auto-boot? true -> Command to set auto-boot

ok help nvramrc -> to view options for storing NV settings
ok nvstore -> to update NV settings
