Recap: PC-NFS 5.0 on a 486 DX connected via ethernet to a Sun 4/470 as server.
Server's filesystems could be mounted on the PC, but any operations would
quickly lock up the PC, the only way out being complete reboot.
The opinions on this were mainly divided between memory clashes and IO clashes
and interrupt clashes. KennedyLemke reported an interesting solution that does
not apply in our setup, which I'll repeat in case it rings bells anywhere:
According to Sun there is a problem using 3Com ethernet boardson a network that
has an MMAC-8 where the PC and the NIS or NFS server sit on the *same* side of
the IRM board of the MMAC-8. Western Digital ethernet boards, for example, do
not have this problem.
Our problem turned out not to be a memory clash or interrupt clash. Two ethernet cards
were tried. There was a clash between the IO address of the first one and the
CD-ROM; this was adjusted, but without complete improvement in operation. The
second card was tried at this point. I had thought that the installer had
checked this card too for IO clash, but he didn't! When Pete Biggs of Oxford's
Physical Chemistry Lab, who knows more about computers than I ever hope to
know, had a look, he sorted it out by moving a jumper on the ethernet board.
Perfect solution. Just shows that everything should be double-checked.
