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.
