That sounds like what I experienced using a fixed-frequency monitor. I
had a Sun monitor that would ONLY do 1280x1024. With an appropriate
video card, I could use it on my PC, but until I was actually running at
that resolution, the screen might be completely unreadable (i.e. in
BIOS), or "squished" as you describe. Games etc. would play fine, but
the display was definitely strange looking if using 800x600, and fuzzy
("stretched") at 640x480. And many laptop LCDs will do the similar
things until at the "right" resolution.
Have you tried loading a GUI on it and trying different resolutions? If
that works, you might be able to load a program to switch video modes on
boot. Under Linux (assuming this is the issue), using a properly
configured framebuffer setup should allow you to run the console (no GUI
required) in the appropriate mode (i.e. "vga=xxx" in lilo.conf),
possibly even maximizing that screen usage a bit.
Oh, and there were BIOS updates for that motherboard to allow higher
speed CPUs to be recognized. I had mine working with my 450MHz K6-2, but
it required some "odd" jumper settings IIRC.
Good luck with it!
