Have you checked this out?

Most motherboards only support four PCI bus master (besides the standard
IDE controller).  Motherboards with "extra" on-board PCI devices or five
PCI slots might share the bus master pins between two slots.  This will
be hidden somewhere in the manual.  You might try moving slots.

The diagnostic program uses the PCI ID.  Intel kept the ID the same
with the i82557, i82558, and i82559.  Curiously, they changed the ID
while leaving the chip the same for a few of the recent models.

Both "ABit" and "RAID motherboard" lead me to suspect the bus master
slot issue.  (Our ABit BP6 systems have slot 4 & 5 share bus master pins.)
