Re: Re:Linux boot disk editing?

["Patrick Mc Govern" <gopat@xxxxxxxxx>]

Hi Adam,
Gee thanks for the help!  I looked at my disk information and noticed the
following:
"/"            is device /dev/hda5      2893Meg partition
"/boot"    is device /dev/hda1          19 Meg partition
These are the default partitions (including my 68 Meg swap partition)
created from the "workstation" settings during installation.

I made the boot disk changes as you advised ("rdev /dev/fd0 /dev/hdb5") and
it did boot the LILO and much of the root system but I got this error:
"Kernel Panic: VFS:  Unable to Mount root fs on 03:05"
I am guessing that since I have a "/boot" partition I needed to add this
command:  "bdev /dev/fd0 /dev/hda1"  ??????

The problem now is that I can't reboot with this disk and edit as planned I
will tinker with making a boot disk from the CD but I was wondering if you
could make a boot disk and bring it to tomorrow's meeting.  I will be there
regardless.  I could also just bring my disk and perhaps someone can bring a
laptop and it can be edited at the meeting??!!
Regardless I am learning a lot and appreciate the configuration capabilities
of Linux.
Thanks a ton.
Pat
