ngle-port 2XP PCI
The single-port 2XP PCI NIC ( Figu re 2-4) is the M y ricom Re v. F card. It supports
one X -port interface and one PCI-X interface. These NICS must use the Myricom
GM-2 or Myrinet Express (MX) software.
Othe
r than the difference in the number of ports, the Rev. F card has the same
spec
ifications as the Rev. E card .
