When I searched for "8KHA+ won't boot" I found my own post from 2005. I've been double booting w/o a problem, but now that doesn't work. I get no video, no text on black background. My PS checks out OK with a voltmeter. If I remember correctly, people with similar problems never found a sol'n. I might check the video card. Will an 8 Mb permedia card, or a 12Mb voodoo2 fit in the slot? I have an ATI sapphire 9500 to 9700np in there now. No bulging resistors/capacitors that I can see. The MB posts to FF which is normal.
