2 weird problems (first ethernet)

[Stephan van Hienen]

first ethernet
ok i put back te card with kernel 2.1.101 (compiled ok)
and booted now it reports :

sunhme.c:v1.2 10/Oct/96 David S. Miller (davem@caipfs.rutgers.edu)
eth0: HAPPY MEAL (PCI/CheerIO) 10/100BaseT Ethernet 08:00:20:96:18:b0
eth1: HAPPY MEAL (PCI/CheerIO) 10/100BaseT Ethernet
08:00:20:96:18:b0        

excuse me same ethernet hardware adress ??

yes its true :

eth0: Auto-Negotiation unsuccessful, trying force link mode
eth0: Link down, cable problem?
eth0: Auto-Negotiation unsuccessful, trying force link mode
eth0: Link down, cable problem?

i then plug it on eth1 (the pci plugin card (with wide scsi connector
external))
and :

eth0: Link is up using internal transceiver at 10Mb/s, Half Duplex. 

what is this ?
can i change the ethernet adres somewehre in de boot prom or something ?

sparc systems have the hardware address burned into the PROM, not the
ethernet device. The behavior you're seeing is correct.

grant.

And furthermore if it is a problem, you can add args to ifconfig to
set the ethernet address on each interface to whatever you like.

This is how sparcs work, they have one ethernet hw address for the
complete workstation. You should never but both interfaces onto the
same physical network.

Nope, the devices are probed depending on bus layout, so eth0 is external
and eth1 is internal.

and what is this arg ?
and is it perm. ?
or do i have to tell it each time ?
(ps is there a way to do this on the boot prom?)
