Because the order of IDE, SCSI, and other hard disks depends on various factors and
Linux is not able to identify the mapping, the sequence in the file device.map can
be set manually. If you encounter problems when booting, check if the sequence in this
file corresponds to the sequence in the BIOS and use the GRUB prompt to modify it
temporarily if necessary. After the Linux system has booted, the file device.map
can be edited permanently with the YaST boot loader module or an editor of your
choice.
IMPORTANT: SATA Disks
Depending on the controller, SATA disks are either recognized as IDE (/dev/hdx)
or SCSI (/dev/sdx) devices.
After manually changing device.map, execute the following command to reinstall
GRUB. This command causes the file device.map to be reloaded and the commands
listed in grub.conf to be executed:
grub --batch < /etc/grub.conf
21.2.3 The File /etc/grub.conf
The third most important GRUB configuration file after menu.lst and device.map
is /etc/grub.conf. This file contains the commands, parameters, and options the
GRUB shell needs for installing the boot loader correctly:
root (hd0,4)
install /grub/stage1 (hd0,3) /grub/stage2 0x8000 (hd0,4)/grub/menu.lst
quit
Meaning of the individual entries:
root (hd0,4)
This command tells GRUB to apply the following commands to the first logical
partition of the first hard disk (the location of the boot files).
install parameter
The command grub should be run with the parameter install. stage1 of the
boot loader should be installed in the the extended partition container
