Is this bug 1566 or another problem?

I've checked the Grub user manual and couldn't find an error like the one I'm seeing.

When I try to boot XP, Grub returns this message and stops:

 Booting 'Windows NT/2000/XP'

root   (hd2,0)
 Filesystem type unknown, partition type 0x7
savedefault
makeactive
chainloader +1

hd2,0 is the correct HD and partition for my XP install (SCSI HD, sdc). The XP partition is 10GB. The C/H/S values freported by the SCSI BIOS at boot show the drive with 255 heads.

I boot Ubuntu off a seperate drive (SATA, sda) and it works fine (set to Large in the BIOS, 240 heads). If I change the boot order of my HD's in the BIOS and make the SCSI drive #1, I can then boot XP off the SCSI HD just fine.

Any thoughts? 

TIA!
