So I just got my 500a, and after smashing keys until it broke into SRM I
was happy to install netbsd.  That is, of course, until I saw the
following messages:

cia0 at mainbus0: DECchip 2117x Core Logic Chipset (Pyxis), pass 1
cia0: extended capabilities: 1<BWEN>
cia0: using BWX for PCI config access
cia0: WARNING: Pyxis pass 1 DMA bug; no bets...

After which it locks up. Is there anyway around this?  I would love to get
this machine working..

Thanks,
Jeff
