Correct ether= parameters for 8139too (RealTek 8139) ?

My apologies for the major spam here but this problem is really causing me havoc :)

Basically my machine has 2xIntel eepro onboard NICs and 1 RealTek 8139 PCI NIC.
My problem is that I am unable to force the RealTek Card register as a specific device namely eth2 - it always decides to register itself as eth0.

Let's take my previous configuration.
Kernel Version : 2.4.17
Let's assume that modules e100 have not been compiled (source Intel who so not support these drivers to be built into the kernel)


alias eth0 e100
alias eth1 e100
alias eth2 8139too

If for whatever reason eth0/1 do not come up eg unresolved symbol/module not installed… The RealTek (8139too) registers itself as eth0 regardless of what options I give eth2…. So I decided to compile 8139too into the kernel in order to parse ether= parameters to it via LILO.

Current Configuration
Kernel Version : 2.4.17 (with 8139too built in)


alias eth0 e100
alias eth1 e100
##alias eth2 8139too (not needed obviously)

No matter what ether= parameters I parse to the kernel at boot time the RealTek card is registered as eth0 :(
So I ended up trying to debug 8139too and recomped it.

Can anyone please indicate what the correct ether= parameters I should be parsing to the kernel in order to register the card to eth2 or even a hack for 8139too.c ?

Here's as much data as I can give you….
Many thanks in advance,
