ACPI is responsible for a ton of different things - including interrupt allocations. try acpi=noirq instead of your acpi=off now and see if it works still... try pci=routeirq if you need to.... Adjusting the DSDT is usually a pretty annoying task since you need to know the hardware pretty well and have lots of patience for testing... > As for BIOS, this is the latest BIOS that I could find available, so > little can I do at that department.

They gear everything so much toward windows and don't care about anything else. Their bioses are beyond buggy and their hardware upgrade options suck (they whitelist the cards they allow you to use in the mini-pci slot!) Got a 11b card? want to upgrade to 11g? Enjoy paying $150 for the upgrade - your generic $19.99 card of ebay will not work. The another major problem I have with compaq is that they change their hardware so often... You never know exactly what you are going to get... So even if someone says I've got a V2413A and it works well, just because you got a V2413AP doesn't mean it will work... Peter.
