Many thanks for your answer!
After playing enough with my lan card I called my ISP and in a few minutes I got connected via my new MAC. I mean connected my laptop, changed its MAC address and there were no problems using the net. Unfortunately my other comp was still not able to find the net
There is something I didn't mention - my NIC is ISA! So lspci won't help me with info. I tried isapnp - no such command. There was no pnpdump either. (Debian booted from 3 diskettes).
It seems that the driver is the correct one. I found a number written on my card and searching the net I found that my card is smc8013 (wd8013) and it works quite well with the driver I choose.
I begin thinking that either my NIC does not function properly or I don't use the right settings for it.
I've read many articles over the net about this NIC. One of them said in the process of booting the IRQ/memory/I/O were not correctly bound the the NIC and that in this case I should give them as parameters at the boot prompt. I did so, but again no success
After such a long battle with this NIC I find a good idea buying another NIC :|
But still if someone advises me about how to make the appropriate settings of my smc8013 lan card I'll definitely give it another try
Thanx
