Diskless Boot with GRIB

Hi

I am trying to boot a diskless client (at the moment a virtual machine in VM) via the network (DHCP server and tftp server on the host). My system: SuSE 10.1

the tftp sever is setup and running and has the image pxegrub available. The DHCP server is setup, buttigning static IP to the VM and has the option "option filename "pxegrub set. I exported the directory where the kernel, GRUB menu config file, ... are located as read write access for the machine VM machines. I checked, and host VM resolves to the IP. I also tried to supply this option to this machine, but this is where the problem comes in. In addition, an "option T150" is defined with the tag 150 as required by GRUB to pbutt the location of the configuration file for the manu (menu.lst). Whenever I try to boot the VM, the GRUB shell comes up and not the menu. My guess is, I need a special way to give the path to the GRUB menu config file. I tried

option T150 "192.168.0.1:--exportedfolder-path-to-menu.lst" and option T150 "-exportedfolder-path-to-menu.lst"

but the VM only opens the GRUB shell.

I am stuck. I am using the pxegrub supplied with my distro (SuSE 10.1) - or do I have to compile it myself (I have the source of GRUB 0.97)?

What is the correct value for option T150?

(with the struggle of loading the kernel, I will deal later!)

Any help welcome,

Rainer
