We've moved to GRUB 2 as a development platform. Please can you check if this bug still applies there, and if it does, reopen it?

Thanks

A problem with device mapping with grub 0.95+cvs20040624-8, under debian sarge. Problem occurs whether stage1 is
located in the HD MBR or on a grub boot floppy.

There are three scsi disks on the bus. The first is sda (sarge, kernel 2.4.18-bf2.4, reiserfs). The sda bootloader also boots sdb (RedHat 8.0, kernel 2.4.18-14, ext3) and sdc (debian sarge, not set up to boot yet, kernel 2.6.7-1-386, reiserfs).

My BIOS sets the disk sequence to be sda, sdb, sdc.
However, grub sees sdb as (hd2) and sdc as (hd1). It sees sda properly as (hd0). To boot these devices, I have to
boot sdb as `root (hd2,0)' and sdc as `root (hd1,0)'.

I tried to alter the /boot/grub/device.map file to read:

(hd0) /dev/sda
(hd1) /dev/sdb
(hd2) /dev/sdc

but this had no effect. I tried a map command before root
in the menu.lst stanzas in order to remap, but this had no
effect either.

The motherboard is Intel D850MVL; BIOS is Award MV85010A.86A.0011 P05.

I was able to boot these three drives under debian woody
(on sda and sdc) with an earlier version of grub (same hardware and BIOS setup).

I created a boot floppy:

grub> install /boot/grub/stage1 d (fd0)
/boot/grub/stage2 p
/boot/grub/menu.lst

but same mapping problem.
