Sounds as if you may have mapped one serial port over the other's I/O addresses or IRQ instead of disabling it. Try using another IRQ for your NIC and leaving COM2: enabled. Also, separate the ranges of I/O ports on the NICs more. Finally, don't use segment C800. It'll conflict with graphics cards. If that's a memory-mapped buffer, find another spot for it. If it's a ROM address, disable the ROM. --Brett At 07:50 PM 8/30/98 -0400, John Baldwin wrote: >-----BEGIN PGP SIGNED MESSAGE----- > >Hi all, > >I've been having some problems with my el cheapo 3Com 3c503 adapters. >Originally, I started out with 1 adapter with a BNC port at io port 0x300, >memory 0xd800, and irq 5.
