I am struggling with the installation of a Western Digital 16-bit Ethercard 
plus. I am not sure quite where the problem lies. The box (Compaq 386/25) 
and the OS (SCO UNIX 3.2R2 with TCP/IP 1.1.1) and choice of I/O (240) and 
IRQ (2) seem to be OK and an 8-bit Ethercard works fine in same location 
and with same settings. After realising that the MAC address seems to be 
read and fixed in when the kernel is relinked, I have been most careful to 
do a remove on the wdn, relink, then install wdn and relink again. Still no 
luck. Symptoms are: either (a) doesn't work at all or (b) works once and 
then quits (i.e. you can ping the host once either in or out, and that 
works, but that's it and nothing more works over the net) Suggestions, 
please?

Also, the WD docs say that 128K RAM is used when running under UNIX; what 
is the best address to use in the mkdev wdn to get the benefit of this? The 
usual D000 is refused if a memory size of 128K is specified. Supplier's 
comment was that "they only ever assigned 8K RAM when using this board"; 
this strikes me as a waste of a high-performance board.

Thanks
