This turned out to be an grub issue. The illegal OpCode message seems
to come the HP hardware/BIOS.
I resolved it by booting using an CentOS cd, doing linux rescue at boot.
>chroot /mnt/sysimage
>grub
grub> device (hd0) /dev/csiss/c0d0
grub> root (hd0,0)
grub> setup (hd0)
It took a couple of attempts, my knowledge of grub is limited. During
the process I also booted from a DOS floppy and did a fdisk /mbr. That
removed the Illegal OpCode which confirmed I was on the right route.
Hopefully this post might help some other poor HP harware user.
Dp.
