Breaking Boot Process on Nextra X1

[abovebrd]

I need to boot into another run level on a Sun Netra X1 server. I have a start up stript in /etc/rc2.d that hangs the system and locks up the boot process.

Is there a way I can boot into into single users mode during the boot process ?

Help

more detail:

I have a SUN Netra X1server. The server runs headless and is managed thru a serial port. I made a change to the ssh conf file. Now when the server boots it simply hangs when that rc2 script executes. I would just assume I could boot into single user mode and fix the rc2 script. Which leads into problem. Since the server is headless and does not have a cdrom or floppy I have no way to boot a boot disk and repair the script. My other thought would be to change the run level at boot time. I know on other flavors you can change the run level at some point in the boot. My problem is I can't figure out how to do that on this box, very perplexing.

Any advice would be appreciated

Just in case anyone one runs into this problem here is the answer. After much research and poor documentation.

Booting into single user mode on a Sun Netra X1 server

1. Break into the lomlite shell "lom>" during boot
#.

2. from the lomlite shell use the "break" command. This will put you at the ROM prompt (OK)
lom> break

Note: I had to run through steps 1 and 2 twice before I was able to break out into the "ROM" prompt (OK)

3. boot -s

4. Now re-mount "/" filesystem with read-write permissions
mount -o remount /

5. Now you can edit the faulty startup script (/etc/rc2.d)
