After reading these guides, you should be aware of the following important information

and precautions pertaining to Myrinet PCI-X and PCI NICs:

• Myrinet-2000 PCI-X NICs support both PCI-X and PCI protocols, and can be used

in any 3.3V PCI slot.

• Myrinet-2000 PCI NICs function correctly in hosts with 32-bit or 64-bit PCI slots,

with either a 33MHz or 66MHz PCI clock, and with either 3.3V or 5V signaling.

•

Myrinet-2000 PCI NICs function correctly in PCI-X slots, except for the PCI-X

slots in some AMD64, EM64T, and PowerPC64 motherboards. Contact

help@myri.com for further details.

• If at all possible, avoid the use of riser cards with Myrinet PCI or PCI-X NICs.

• We recommend that the Myrinet-2000 PCI (or PCI-X) NIC is installed into the PCI

(or PCI-X) slot closest to the PCI chipset.
