Re: minimal files

[Pascal]

hi,

here is my new configuration that works in virtual machine and on the few
physical machines I had in hands. :-)
do you think everything is there with Grub 2.04 ?
is the video.lst file necessary from the moment I load the video modules
manually (insmod in grub.cfg) ?
is the ieee1275_fb video module necessary for a PC ?
