[SLUG] About those RTL8139 network cards... :P

Oops :P
This discussion got me to take another look at the card(s). I downloaded
Donald Becker's tools, in Debian unstable/sid as nictools-nonpci and

It seemed it was a stupid IRQ problem. I guess PCI isn't totally idiot
proof. See, ages ago I had disabled the printer port on this motherboard
when I was satisfied with my printer working over USB. I had also set
IRQ 7 as "PnP/PCI" in the BIOS PnP setup screen. It happened that both the
RTL8139 cards were getting assigned IRQ 7 (and probably another network
card now that I think about it...).

So last night I enabled the printer port and set IRQ 7 back to "Legacy" in
the BIOS. Bingo. The card worked OK then.

So...um...I guess I have to take back any ill-will I attributed to RealTek
and 8139-based network cards. Sorry, my bad :P

Yeah, and now I have to figure out how to get the Tulip card to talk 100Mb
to my 10/100 ethernet switch. The D-link card does it OK, although I 
couldn't force it to do 10Mb.

My bad,
