PCI Buses

[Michel Lanners]

Hi Tom,

On  15 Aug, this message from tom_gall at vnet.ibm.com echoed through cyberspace:

Wrong :-)

As has been said before, the 9x00 have two PCI busses on two identical
bandit host bridges.

Also, the 73/75/76/85/8600 have an additional bus called VCI by Apple,
for accessing video in/out hardware, that behaves exactly like a PCI
bus.

Then, there are newer Macs, with those based on UniNorth having three
PCI buses (AGP counted in).
