Does choice of PCI-slot matter with Windows 2000 installed in ACPI mode?

[Bernd Bubis]

Does it matter, which PCI-slots I choose for my PCI-cards? Usually I'd
like to say yes, because of the shared-IRQ issue.

However, with Windows 2000 installed in ACPI mode (device manager
shows under the entry "computer" the entry "ACPI-PC"), Windows seems
to assign all PCI-cards the *same* IRQ anyhow. So one might think it
totally does not matter anymore, which PCI-slot to choose for the
different PCI-cards.

Am I wrong?

My system setup is this:

Motherboard: ABIT ST6 with newest BIOS-Version 9P
CPU : Pentium III Tualatin FCPGA-2 1 GHz
Grafics : ATI Radeon 9000
USB2 : Adaptec AUA-2000LP (two USB 2.0 ports)
WLAN : D-Link AirPlus DWL-520+
Printer : HP Deskjet 1220C

No, you're correct. The only thing to take into account is a decent
airflow for the AGP card cooling fan.

in most cases....however some older modems and NIC's will only install if you turn off PNP OS installed in the BIOS, then use
whatever PCI slot. PCI #1 should still be avoided if possible
