Did you boot each card in a machine via the Etherboot floppy disk first? When the driver first executes correctly, it programs the NVRAM on the card for the MII mode, which enables the correct ROM-mapping. The majority of the cards we have here are 40-0483-004 cards. I don't remember the revision '3c905B rev [ABC]' printed on the card itself. > There is one point, that I don't understand at all.

No idea what > happened, no chance to reproduce. My guess would be that the one particular card ended up in a machine that was booted from an etherboot 3c90x.fd0 image on floppy.... But, that's just a guess :) Let me know if you make any progress, Greg. ------------------------------------------------------------------------ Greg.Beeley@LightSys.org LightSys - Redeeming Technology... http://www.LightSys.org For God's Kingdom. ------------------------------------------------------------------------ =========================================================================== This Mail was sent to netboot mailing list by: Greg Beeley <Greg.Beeley@LightSys.org> To get help about this list, send a mail with 'help' as the only string in it's body to majordomo@baghira.han.de.
