Poor Man´s Installation and the config.sys

I am trying the poor man´s installation as described in http://www.knoppix.net/wiki/Win_Partition.
Part of the procedure are changes to the config.sys in order to generate a boot menue where the choice between Win98 and Grub/Linux is presented. The Wiki does not describe the changes in config.sys in detail. So I did what I thought was necessary and surprisingly it worked, but when i boot into Win98 with the new config.sys I get an error message about gemback.exe causing problem in the kernel. Gemback.exe is part of the AMD power now application...
When I reinstall the old config.sys there is no error message. My tired eyes don´t see what in my config.sys could cause any problems for gemback.exe and what I could do about it. Any ideas?

This is what the old config.sys looked like before
device=C:\WINDOWS\COMMAND\display.sys con=(ega,,1)
Country=049,850,C:\WINDOWS\COMMAND\country.sys

This is the new config.sys:
[MENU]
menuitem=Win,Windows98
menuitem=GRUB,Linux
MENUDEFAULT=Win,5
[GRUB]
SHELL=GRUB.EXE
[Win]
device=C:\WINDOWS\COMMAND\display.sys con=(ega,,1)
Country=049,850,C:\WINDOWS\COMMAND\country.sys
