We've had problems with the 3Com cards in Pentium computers. We've seen the kinds of problems you mention under Interactive UNIX, FreeBSD and Win95. I believe there may be a hardware problem in their parallel architecture. Perhaps a race condition in some state machine? Anyway, in all cases we got satisfaction by replacing the 3Com card with one from another manufacturer. The Intel Ether Express seems to work for us. Unfortunate, because we had sorta settled on 3Com as a standard. -crl -- Chad R.
