<DIV>hate to be clogging up the list but memcpy works!!</DIV>
<DIV>It looks like the VT8622/8623/8635 all have the same way</DIV>
<DIV>of dealing with this shadow copy stuff. After losing a</DIV>
<DIV>couple of hours sleep, I've hit another snag here (partial log):</DIV>
<DIV> </DIV>

<DIV>
<DIV>I've tried to put some debugging outputs but the system</DIV>
<DIV>just grinds to a halt after the second call to biosint().</DIV>
<DIV>It's now my belief that directly manipulating the registers on
the Apollo</DIV>
<DIV>CLE266 northbridge might yield better results for the epia M.</DIV>
<DIV>VIA doesn't seem inclined to give out the datasheets or source code, as the
posts on viaarena indicate. I wonder if looking at the linux driver
patches for kernel 2.4 and greater might offer some clues. Any help
would be greatly appreciated!</DIV></DIV></FONT></BODY></HTML>
