Very Computer

I haven't seen anything on this and I was curious whether it
exists or not...

TIA,

 Chip           Boards
DEC21140        SMC EtherPower 10/100, DEC, many other vendors.

                file://cesdis.gsfc.nasa.gov/pub/linux/drivers/new-tulip.c
                (Also, recent versions of the de4x5.c driver works with DEC
                 produced 100mbps boards.)

3Com Vortex     On the 3Com PCI 3c595, 10mbps-only PCI version is 3c590.
                 (A new EISA version has just be announced -- that means
                  I must find an EISA machine to update the driver...)

Unsupported for now:
NatSemi ???     An NatSemi-produced ISA 100baseTx board.
                I may write a driver in late September.
Intel           Intel EtherExpress Pro 100

                documentation from Intel without a restrictive NDA.

There are also two 100VG drivers in alpha test, mine for the ISA/EISA/PCI
boards, and another for ISA/EISA boards.

For the latest driver information you might want to monitor

For more info on 100Mbps choices read
        http://cesdis.gsfc.nasa.gov/linux/misc/100mbs.html

P.S. I have been doing most of my performance tuning with the SMC EtherPower
adapters  -- we have 40 of them on our Beowulf Linux clusters.  Currently I'm
seeing about 4.6MB/sec application-to-application with TCP using a single
network.  The configuration is two ethercards on each P5-100 Triton
motherboard, interconnected by NetWorth 8 port repeaters.
