Suse 9.3 - Dual boot issue - filesystem type unknown 0x7

I am having a frustrating situation. After updating my motherboard bios, I was unable to dual boot my system. I run Suse 9.3 and Windows XP professional. Both were living in harmony before the bios update but now whenever I try to boot into Windows I recieve the error "Filesystem type unknown 0x7"
Linux, of course, boots fine.
My system consists of 3 hard drives. The first is an EIDE drive, on which I have Suse. The other two are SATA drives (74Gb and 300Gb respectively), the 74Gb being the main Windows hard drive, the other being used as storage for Windows programs.

Here is a copy of my /boot/grub/menu.lst

After doing some research online it does appear that other people seem to have had this problem but mainly with Suse 9.1. I tried the driver update that I've seen on other posts but that didn't work, probably because that was for Suse 9.1 and I'm running Suse 9.3.

Any help with this situation would be greatly appreciated.

Thank you in advance,

error "Filesystem type unknown 0x7"
As far as I can tell, 0x7 is the filesystem code for Windows NTFS. Must have been a faulty bios upgrade. Did you check your bios for any new changes since the old bios? You can also try to reinstall grub and see if it boots. I'm not too familiar with SuSE but checkout YAST and it should have options to configure bootloader.
