ok-
taking these suggestions (and I concur, grub is a lot easier) I still
have the same problem with the kernel panic. / is on /dev/hda1 swap
on /dev/hda2; grub recognizes the new kernel and it is an option on
the menu. I went back and re-verifed that ext2 and ext3 filesystems
are configured into the kernel and *NOT* as modules. I did a make
clean and a make-dpkg clean and recompiled and re-installed the new
kernel. No compilation errors, no installation errors, but still the
same can't mount root fs error.
One thing I'm confused on is the ide drivers in the 2.6 kernel. While
reading the help under ATA, etc. it states that I should be using the
scsi driver for ide drives unless I have legacy equipment (which I
don't, Vision computers x86 based, new in the last 2 weeks), but under
the scsi drivers section it asks for a specific driver and does not
list anything remotely close to what i've got.
So, I'm at a logjam.
Thanks for the help

Post /etc/fstab
Here is /boot/grub/menu.lst
and /etc/fstab
One other thing that I have found in my searching is that my ide disks
might be handled by the scsi driver and I am considering trying that
(changing from /dev/hda to /dev/sda) but I am confused as to how to
verify that this behaviour applies. I'm fairly certain that this does
not apply in this case.
Thanks.
