Hello Jonathan!

Wow, talk about a quick response!

Now I'm confused (aren't I always? =o) Someone recently told
me that 3Com cards were great for DOS and MS-Windows because
they wrote good drivers for them, but were technically not
all they were cracked up to be - he didn't recommend them
for BSD.

I've used 3c509 NICs before, and I recall being told that
the 3C509b was better than the 3C509a because the former
would only interrupt when it received a packet meant
specifically for it, rather than for every packet received
which the latter apparently did.  Can you confirm this?

For the record I can pick up the Realtek ISA cards locally
for US$ 20.

On some of the earlier combo cards it was pretty simple to
switch between 10 Base-2 and 10 Base-T, you just set a
jumper. I /think/ with the Realtek cards that it was done in
the flash configuration program where you set base address,
IRQ etc.  Is full-duplex usually a good thing on 10 Base-T?

I don't think I'd want to attempt 100MB/s on a PC-Card
unless I was using Cardbus (32-bit PCMCIA).  I may have
Cardbus, but I'm setting up 10 Base-T anyway.

  JS> At least we have support for the Realtek cards ;)

Yep, and that's something I'm greatful for!  =o)
