Well, it apears the system boots just fine without the initial ramdisk,
so what I would try is commenting out the initrd lines, and see if that
helps. Now, as far as the difference between "root=/dev/hda5 ro
vga=791" and "ro root=/dev/hda5 vga=773", except for the vga mode, there
is no difference. You could use "ro root=/dev/hda5" and it should boot
as well.
What I would do is backup grub.conf, and create a simple one to test
things out.
default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Red Hat Linux
root (hd0,0)
kernel /vmlinuz-2.4.18-26.7.x ro root=/dev/hda5
See if that works. Expand from there.
