SubjectPROBLEM: Xircom Realport gets MAC 00:00:00...... Card known good.
This is very verbose. Sorry. I much prefer to toss all the pieces on the
table at the same time.

Dag B

[1.] One line summary of the problem:
-test7/8 version of xircom_tulip_cb does not enable my Xircom Realport
(RBEM56G-100)

Nor any of the other kernels I have tried...


[2.] Full description of the problem/report:
My Xircom Realport (RBEM56G-100) is causing headaches. It works with
NT4/SP5 on my Dell CPi laptop, so the hardware is functional. (Tested
this morning. )
When loading the xircom_tulip_cb.c:v0.91 driver, things looks ok, until
you study the MAC address, which is all zeros. What follows is the
output from -test7 and test8:

I can use ifconfig to set a hw-address (does the card really support
this?), but if I try to set an IP-address, the system hangs hard.

Donald Becker's tulip-diag says:

Port selection is MII, half-duplex.
Transmit stopped, Receive stopped, half-duplex.

The transmit threshold is 128.
The NWay status register is 000000c6.
EEPROM size is 8.
WARNING: The EEPROM is missing or erased!
This interface is missing the EEPROM.

This is a 10/100BaseTX/56K modem combo card. Loading serial_cb produces
nothing. And the card still works under that other OS...
