Actually, the ATA controllers are attached to the 32 bit, 33MHz PCI buss 1 located on the south bridge AMD 768 chip. I'm guessing the problem has to do with the buss numbering. What mystifies me is why does it work under Win 2000 and not Win XP. I would guess that the updater is written in C. Sometimes some of the compilers have switches that can be set to optimize them for certain classes of processors or other circumstances. Since this action is happening at a real low level, there may be some routine that takes device and buss numbering into consideration. The HP drive I mentioned in the previous post wouldn't update under either Win 2000 or Win XP in either of two different PCs with MBs that have this AMD chip set with the two PCI busses, but worked when I put it into a PC with a standard buss set up. I wonder if people will have trouble with some of the new PCs with dual Opteron MBs that have split PCI busses.
