RaQ Console gives the following errors:

Dennis Charnoivanov came with a kernel that debugs the tulip code, giving this output on the console:

>How-To-Repeat:
Install Netbsd (netboot) on this particular RaQ2+ (R28 GF8 FIE).
(dual nic, scsi, 256MB RAM).

>Fix:
Dennis customised the kernel so that it doesn't check the contents of the SROM. 

Succesfull, the raq did a netboot and I was able to login and ping a host.

He found the "solution" unacceptable and asked me to fill in a problem report and add the following patch (tulip.diff):
