3c905b-tx 100tx?

I have two 3c905b-tx nics.
Drivers compiled in the kernel.
They only transfer at 10mbs.
If I loaded modules, options=4 should make them transfer at 100mbs.

Can I make them transfer at 100mbs without using modules?

try checking the NICs with 3coms diagnostic program.  It could be that they're set for 10Mbps and not auto detect.

What operating system do you have?

with redhat 6.2 and above you can use 3C59x driver that comes with it.  I use it and it works great at 100mbps.

Good Luck,

I have "3c590/3c900 Vortex/Boomerang" compiled in kernel 2.4.5
The help says it's the correct driver.

Dmesg:
eth1: 3Com PCI 3c905B Cyclone 100baseTx at 0xe800,  00:10:5a:ca:31:64, IRQ 11
  product code 5152 rev 00.12 date 11-01-98
  8K byte-wide RAM 5:3 Rx:Tx split, 10baseT interface.
  Enabling bus-master transmits and whole-frame receives.
eth1: scatter/gather enabled. h/w checksums enabled


I tried a crossover cable and a switch that routes on the mac address.
Works at 100mbs with windows2000.

I have 7.1 too and I used linuxconf and choose 3c59x for each of my three network cards in my server.  They are all detected and function at 100 mbps while connected to a 100mbps 3Com switch.

I didn't know there were dos utilities for pci cards.
That was it.
