I pulled all of my remaining hair out yesterday trying to suss his out.
Setting up a dual-boot 98SE and XP rig on an Asus P2B-F with 1GHz SL4BS P3. Both OS's are installed and boot up fine. Only the graphics card is installed at this point.
XP runs fine for as long as you want. But boot into DOS or 98 and it hangs/locks up within 2-3 minutes. It does this whether you go into normal mode, Safe mode, command prompt, or boot into DOS separately from a floppy.
I've swapped RAM, changed timing settings in the BIOS, anything timing-related I could think of, but no diff.
Any idea what might be causing this? I'm stumped.
