Strange GRUB problems, error 25

Hi, I'm having some issues installing Arch on my system. GRUB refuses to recognise my two PATA hard drives.

I have Windows Vista installed on a 320gb SATA drive which boots fine and I've installed Arch on the 120gb PATA for dual booting.

My motherboard seems to refuse to boot from both PATA drives though; so I've put grub on the MBR of the 320gb and set menu.lst appropriately to boot Arch from the 120.

When I boot, grub just gives an Error 25. Attempting to root (hd1,0) in grub on the Arch CD before the kernel loads gives the same Error 25. Same with grub on Super GRUB Boot. But loading grub on the Arch CD after the kernel loads recognises all my drives fine.

My motherboard is a GA-P35-DS3L rev. 2 (BIOS P7).
Both ATA hard drives are Seagate Barracudas; 120gb and 80gb.

Any ideas?

Grub on your harddrive gets the disk order from the bios, this can be DIFFERENT from the order detected after a kernel has been booted.

Try hd2,0 and hd0,0  if neither works please post your /boot/grub/menu.lst .

Re: Strange GRUB problems, error 25

Is the bios set to use "native" or "legacy/compatibility" mode for the drives?  Try toggling to the other setting & see if that helps.  Some people have to use one or the other to get the drives correctly booting.  Asus boards seem to be OK with the Native or SATA setting but some Gigabyte boards prefer (it seems) the "Legacy" setting, or whatever its called in their bios.
