Hello Chuck,

Thursday, March 28, 2002, 5:29:28 PM, you textually orated:

Well, you have to do the math and remember all the things involved.

Standard PCI channel = 32 bits
Running at 66Mhz (66,000,000)

32bits * 66,000,000 per sec = 2112000000 bps =~ 2 Gbps

2Gbps > 1Gbps :)

So yes a standard PCI bus (@ 66Mhz) can provide enough for a Gigabit
Ethernet adapter with room to spare (of course the bus is shared so actual
throughput will vary).

Have fun,
--
