На реальном железе сеть не работает.
On real hardware, the network does not work.
"Intel 82547EI" Intel PRO/1000 CT
"Intel RC82540EM" Intel PRO/1000 MT
"Intel SB82558B " Compaq NC3121
All three listed cards should work already.
"Does not work" is however a very poor bug report..
Is the card detected?
Is the MAC address of the card correctly corrected? (Check netstat program)
Is the link detected? (when a network cable is plugged in, check netstat program)
Does receiving work? (check netstat program for received packets)
Does sending work? (check with direct cable connection to another PC running wireshark)
Are there any errors present on the debug board?
