Re: SMP Woes

Howdy,

I figured out the MPS 1.4 issue, it was enabled in my BIOS. I just
downloaded 2.6.5 and installed it. Everything works except the video mode. I
have "vga=791" in lilo.conf, which has worked on every kernel I've ever
built. 2.6.5 just ignores it. Ireadup a little on the vesafb, it has a lot
more stuff about configuring then I've seen before. In a bit I'm going to
reboot with "vga=ask" to see if I can use something different.
