Hmm, this is curious. It boots quickly now. I don't know why. I've been installing the drivers for my cards and what not, fiddled with the BIOS a little. Suddenly it rockets through that first screen.
All I can think is that it's something in the BIOS. I turned off the USB keyboard and Mouse supports, both serials, the built in sound, the parallel port, maybe another thing or two I didn't need. It was pro'lly one of them.
Give it a shot.
For this latest BIOS, maybe it isn't all inclusive. I get the 5 - 12.5 multiplier range, but there is no interleave option. Rats, I just flashed it last night, might have to try out the other one. It works, but it makes me nervous every time...
