Grub and autoyast (getting null for device?)

Hi, all: We are running into problem installing grub via autoyast installation. Here is the error: cat /etc/grub.conf | /usr/sbin/grub --batch --device-map=/boot/grub/device.map GRUB version 0.93 (640K lower / 3072K upper memory) [ Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists the possible completions of a device/filename. ] grub> root (null) Error 23: Error while parsing number grub> install --stage2=/boot/grub/stage2 /grub/stage1 d (hd0,0) /grub/stage2 0x8000 (null)/grub/menu.lst Error 12: Invalid device requested grub> quit Yast install is using (null) instead of (hd0,0). The device.map seems to be fine, and we have tried to reduced the bootloader sectin on autoinst.xml to minimum: <bootloader> <activate config:type="boolean">true</activate> grub <location></location> </bootloader> It didn't help either, using /dev/sda in the loader_device section. Yast always gets (null). Where is yast reading this value from and what can we do to fix it? Thanks in advance for any help. Regards, Ben
