Options to disable com ports/LPT ports in Tandy machines?

Post by keenerb »

I've been unable to get an NE2000 adapter working on a Tandy 1000 machine.

MSD reports all irqs are used and detected.

Adding the NE2000 compatible device lets me load the packet driver and attempt mtcp dhcp lease, but never sees any packets.

The same configuration does work in system with unallocated higher IRQs, like a basic 286/386 emulated system.

The 1000HX setup program doesn't show any way to disable the ports, and there was never a COM2 on an HX anyway by default.

Any suggestions on how to free up an IRQ for the NE2000 here? The screenshot shows IRQ7 is NE2000 but that's because I forgot to unload the TSR; it's detected and handled by "system area" without the tsr loaded.
