[mythtv-users] Day one with HD3000 - bust

[Michael J. Lynch]

Bus mastering shouldn't have a thing to do with it.  The BIOS should 
still be
able to detect the board.  Detection of hardware on the PCI bus occurs via
special cycles on the bus called "configuration cycles".  Bus mastering 
is not
used (or supported) with configuration cycles.  If a card is not being 
detected
it means that it did not respond to configuration cycles used to read (at a
minimum) it's vendor and device id configuration registers.

My guess is that the problem is something more basic like 5V only cards in
3.3 V slots or something like that.  If so, a new MB is probably the only
solution.
