Re: 3com905B cyclone not working



I had extensive troubles with the 3C905B.  I have a dual boot system with
Windows 95 and Linux.  If I do a soft reboot from Windows, I get the
ff:ff:.. problem, so I always have to turn off my computer when I want to
go from Windows to Linux.  Also, these cards have a documented problem
with optaining IP's via DHCP on 10Base-T networks.  This problem occurs in
all 905B's up to revision 'C'.
