10/100 network cards

I have a couple of computers at home, connected with a 10/100
D-Link switch. The cards are all 10/100 3Com (deriver 3c59x under
RH9, kernel 2.4.22) and an onboard Intel card (e100 under Fedora 1,
kernel 2.6).

The transfer rates (with scp) are always about 1 Mega bytes/sec, so
that's about 800 Mega bits per second. Not quite 10 Mbps, but
definitely not 100Mbps. Why don't I get 100 Mbps? Can I configure
the cards and the switch to achieve that? How? I'm guessing it has
something to do with autonegociation, but I don't know details.

Thanks!

You could check the current NIC settings with mii-tool.
