Re: SCSI-Problem

[Christoph Plattner]

Hello,

we could communicate in German, but we want to stay international ....

First of all try a current version of GRUB (0.90, CVS snapshot, etc...)

The BIOS has a config, if to boot from SCSI or IDE. This setting also
influences
GRUB, as (hd0) is an IDE disk or a SCSI disk (SCSI first). So the
simplest way 
is to do the BIOS setup to have SCSI first, then boot from floppy.
On the command line of GRUB use

        setup (hd0) (hd0,0)

to install GRUB on the first BIOS disk, which is the SCSI now.

To do a setup via GRUB from Linux, and if you have no special kernel
option
used for reordering the disk devices, then the best way is to use map
file,
like `/boot/grub/device.map' with the contents of

(hd0) /dev/sda
(hd1) /dev/sdb
(hd2) /dev/hda
(hd3) /dev/hdb or hdc

This file is read by `/sbin/grub' and used for the device mapping. With
this
setup and the activated BIOS option to have SCSI first, everything has a
consistent view.

Bye (Mfg)
