GRUB Boot Fails on P3 without Keyboard

[Rebecca.R.Hepper at seagate.com]

My RH9 P3 systems fail to boot GRUB while the P4 systems boot without any
problems.  When the P3 tries to boot, it hangs before the RedHat Linux
interactive setup at a line that says "apm: BIOS version 1.2 Flags 0x03
(Driver version 1.16)".  If a keyboard is attached to the P3, it will boot
without issues but the system must boot without a keyboard.  The P3 will
boot LILO without a keyboard attached.  Any idea how to get GRUB to boot
without a keyboard on the P3's?

Thanks!

The grub-0.93-4 RPM is installed.

This is my grub.conf:
default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Red Hat Linux (2.4.20-30.9smp)
      root (hd0,0)
      kernel /vmlinuz-2.4.20-30.9smp ro root=LABEL=/
      initrd /initrd-2.4.20-30.9smp.img
title Red Hat Linux-up (2.4.20-30.9)
      root (hd0,0)
      kernel /vmlinuz-2.4.20-30.9 ro root=LABEL=/
      initrd /initrd-2.4.20-30.9.img
