I just updated my server to a new version of Bios, and now Grub does not load.

It loads stage1.5 but just hangs loading stage2

If I boot with a rescue disk (CentOS5.4), I can reinstall grub without any errors.

The only way I can now boot is to use a Super-Grub iso image, and then I can boot off the local disk.

The local disk is a 3Ware 9500SX SATA-RAID

Any help would be appreciated.
