[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.
