[LinuxBIOS] LB vs Factory BIOS -- more weirdness

I have done this -- It doesn't cause the problem. I had the machine off
for two days with the PS unplugged (no aux power), and the power
connected disconnected from the MLB. Booted just fine after that. I
think whoever mentioned the CAS setting being too fast might be on the
right track, but it's weird that the factory BIOS fixes it (for a while).
WRT DMA issue:
(I only booted using LB)
Also, last night, I _hammered_ the southbridge by copying 50M files on
the HD, FTPing 50Meg files, and Copying 100M files from usb stick to
HDA. I ran this for several hours. The CPU heatsink got pretty warm.
No crashes. Previously, just copying from HDA to HDC would crash it, or
from USB >> HDA, regularly.
So I Power down, Reboot (LB again), restarted the HDA >> HDA copy and
the FTP. Froze up within 10 minutes.
I'll re-run the tests tonight using the factory BIOS -- who knows what's
going to happen.
