Problems booting from mixed scsi/ide

[Dr. Tilmann Bubeck]

I'm having trouble installing GRUB 0.92 on my system consisting of 1
scsi and 2 ide drives. GRUB should be installed on the first (and
only) scsi drive. I did as recommended:

grub> find /boot/grub/stage1
hd(2,0)
grub> root (hd2,0)
 ... filesystem is ext2 ...
grub> setup (hd2)
 ... installing ...

However, when I reboot the computer I simply get "GRUB Hard Disk Error". :-(

As a temporary workaround I removed the ide drives from my computer
and did it again:

grub> find /boot/grub/stage1
hd(0,0)
grub> root (hd0,0)
 ... filesystem is ext2 ...
grub> setup (hd0)
 ... installing ...

Then everything worked! Please recognize, that it's now hd0, instead of hd2.

I guess the problem is the mapping between bios drives and real hard
drives (hd2 vs. hd0). I tried HDBIAS "2" as an additional parameter to
"root" but did not succeed.

My questions are: Is there any way to install grub without removing
the ide drives? What is the right bios name? What is HDBIAS? How do I find
out the mapping between bios and linux?

Thanks
  Till
