Пришлось конечно поискать этот Атстой. Hашел такой:

Index #1: Found a Realtek 8029 adapter at 0x5c60.
The 8390 core appears to be active, so some registers will not be read.
To see all register values use the '-f' flag.
Initial window 0, registers values by window:
Window 0: 22 04 51 ff 03 00 00 00 06 00 50 43 21 00 00 00.
Window 1: 62 00 c0 df f1 c7 1c 51 00 00 00 80 40 00 00 40.
Window 2: a2 00 80 ff 40 ff ff ff ff ff ff ff cc e0 c9 bf.
Window 3: e2 30 ff 00 ff 00 30 ff ff ff ff ff ff ff 29 80.
RTL8029 transceiver: 10baseT/coax (autoselected on 10baseT link beat) half
duplex.
0K boot ROM.
No interrupt sources are pending (00).
Parsing the EEPROM of a RTL8029:
Station Address 00:C0:DF:F1:C7:1C (used as the ethernet address).
Configuration is 30 00:
0K boot ROM, half duplex
Transceiver: 10baseT/coax (autoselected on 10baseT link beat).
PCI Vendor ID 0xffff Device ID 0xffff
Subsystem ID: vendor 0xffff device 0xffff
Use '-a' or '-aa' to show device registers,
'-e' to show EEPROM contents, -ee for parsed contents,
or '-m' or '-mm' to show MII management registers.

Мне кажется что миф о ненастраиваемости mac на 8029 имеет весьма
значительную историю. Hе мойму только почему в то время пока эта карточка
была еще актуальна никому не сподобилось проверить этот гон ?
