IRQ allocation in w2k

[CocaCola5]

I have a question about IRQ in w2k, after I setup w2k, I notice that both my SCSI(uw) card and Promise ata100 card were sharing the same IRQ(11). I went to try to manually change on of them to a different IRQ and it won't let me, the system greyed out the values. I have the MSI Pro2a board and I remember setting the bios to allow manual IRQ control before I started the installation.

if ACPI is on in the bios this is the way windows sets up irq's it should work fine

Yup, because you installed Win2K with ACPI enabled, Win2K takes over and allocates the IRQs to virtual IRQs. If you want to manually set them... you can go into your system properties and change it to a standard pc. But if you are not expiriencing any problems, leave it...
