Trying using "boot -s cdrom"  That will boot you in a single user mode off a
mini-root from the CDROM and give you limited functionality, but enough to
run a good fsck.

Good Luck

Subject:	[SunHELP] booting from cdrom

Okay, listers, what in the heck am I doing wrong here?....

I need to boot from cdrom so as to run an "fsck -of" against all filesystems
on one of my servers.
I have tried this on two servers using the CD labelled "Solaris 2.6 Software
5/98 Server Configuration".  In each case,
I have gotten to the ok prompt and have typed "boot cdrom".  On one server,
I wind up getting the error message:

Short disk read			(SparcStation 20)

On the other server, I get the message: 

failed to read super block	(Ultra 5)
failed to read super block
Boot load failed.
The file just loaded does not appear to be executable.

Am I doing something wrong with my boot command (ie. does it need some other
argument/option)?  Can you boot a server
from ANY Solaris type CD?  (I've also tried using the CD labelled "Solaris
Server Intranet Extension 1.0".)

Thanks in advance for any/all information.
