Two steps you might consider:
First, make a boot disk and a rescue disk. If you're using Red Hat, the
images are in the /images directory of the cd. Use rawrite.exe from the
/dosutils directory. Then boot with the boot diskette, and at the prompt
type "rescue" (without the quotes). You will be prompted for the rescue
disk as the system boots. Once booted, you need to run fsck on the Linux
partition. For instance, if Linux is on the second primary partition of the
first IDE drive, you would type "fsck -t ext2 /dev/hda2" and hit enter. If
there is filesystem corruption, you'll be notified. :) Once fsck is done,
your drive should have been repaired. Remove the floppy and reboot the
system by typing "init 6" and hit enter.
The first time you boot the system after the repair, at the "boot:" prompt,
type "linux single" and hit enter. The system will come up in single user
mode, which means you are logged in as root without being prompted for a
password. Then just run "passwd" and change your password, and then "passwd
fred" to change a user named fred's password.

Subject: root pwd corrupted-help.
I ran the 2.2.5 box for a month (fo0lishly) without
rigorously testing to make sure the overclocking wasn't
making small errors. When I rebooted the other day,
it booted fully (and can boot into Windows fine) but
when I got to the login prompt, it won't accept my
root pwd or my user pwd. I'm thinking it's because
the pwd data is corrupted from overclocking--dual celeron
366 -> 550, bus at 100mhz (which doesn't cause any probs
for the HD bus, because this is standard).
Any suggestions on what to do to recover my pwds and
login, and steps to take to detect data corruption and
also to diagnose how fast I can safely overclock are
requested.
thanks,
Chris Johnson
