Ivanovic" Cc: linux-smp@vger.kernel.org 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.
