FreeBSD works fine on motherboards with 64bit PCI slots.
Mine has two 64bit 66mhz PCI slots, its an Asus A7M266-D Dual Athlon boa=
I'm running an Adaptec 29160 (U160 SCSI) 64bit 33mhz card.
Please note the following details:
1) 64bit slots may run on two 'speeds', 66mhz and 33mhz. If you mix PCI =
which run on each speed, then the BUS and all the cards will run at 33mh=
To run at 66mhz, ALL your 64bit PCI cards must be 66mhz capable.
2) There are two voltages, 5.0V and 3.3V. Some PCI cards support both vo=
and others only support one of them. Make sure that your PCI card has th=
correct voltage, otherwise it won't run.
3) Take a look at this forum, it explains in detail the bandwidth proper=
of 64bit/32bit PCI bus running at 66mhz/33mhz.
4) As a side note, 64bit bus with a 64bit PCI card is a "good thing to =
have" if you
run 20 or more SCSI RAID 10k rpm drives.
I hope it helps.
