W2K detects non-existent ports and BSOD's!! How to disable auto-detection?

I have disabled COM1, 2 and LPT1 in my server's BIOS, to allow enough IRQ's
to be available for two 3COM PCI internal modems in the machine. In the
BIOS this appears correctly and it reports the devices. However, when W2K
(fully patches with all SP's and hotfixes) starts it detects com1, com2 and
lpt1 anyway, and then reports that the second modem has a problem. When I
force the IRQ's, after disabling the incorrectly detected com and lpt ports,
the machine crashes with a BSOD.

I moved the modems to a totally different server (a dual 1GHz PIII server)
and the problem is exactly the same, so my suspicion that the BIOS in the
Dell PE1400 is the problem, was proven wrong. It's actually windows 2000
server that stuffs this up.

So my question is: Is it possible to tell W2K that no COM or LPT ports are
installed? (ie I don't want auto-detection). I think then I'd be able to
manually config the modems to work correctly. Of course I don't want the
modems autodetected either...

Sounds like you are still having a IRQ conflict. Can you change the IRQ
address on the other modems?

 

Clearly I do, but I cannot fix it. Consider what I've done to date:

I booted safe mode and removed all modems and ports. Disabled the ports
(Com1,2 and LPT1) in the BIOS.
On normal startup the ports are immediately redetected and installed. One
modem has an available IRQ and is fine, the other reports a problem (but not
specifically a resource conflict)
So I disabled the com and lpt ports in hardware manager.
Still the modem doesn't work.
If I then (with com1,2 and lpt1 disabled) choose a different IRQ for the
modem, or a different port, the ports are available for selection. However,
when select COM1 for a modem for example, and click apply, the machine
crashes immediately.

Both machines have identical behaviour, which leads me to believe it's a
windows problem.

I cannot assign the resources in Safe Mode, just enable/disable, so I have
to boot normally to do that.

that's about it till now.
