Experiment with enabling or disabling all the combinations of possible settings to try to get the desired results. At times, the BIOS setting that you may or may not have, PnP Aware OS, also has a bearing on these settings....(See below for more info)
Make sure you do a full reboot after every change while testing.
IRQ Steering
Use IRQ Steering - Specifies that Windows programs use IRQ steering. If you select the Use IRQ Steering check box, PCI bus devices behave more like Plug and Play devices. If you click to clear the Use IRQ Steering check box, then BIOS programs dictate IRQ steering.
IRQ steering is determined by one of four routing TABLEs. Windows searches for one of the selected routing TABLEs in the order listed anduses the first one it finds.
Do not change the default settings for IRQ steering unless there is a problem with a PCI device
If there is a problem, click to clear the Get IRQ TABLE using ACPI BIOS check box and restart Windows
If the problempersists, select the Get IRQ TABLE from Protected Mode PCI BIOS 2.1 call check box and restart Windows
Select the Get IRQ TABLE from Protected Mode PCI BIOS 2.1 call check box only if a PCI device is not working properly
One combination that worked for a number of people was to go into your system's BIOS, and make sure that ACPI I/O Node is set to Enabled, and to set the IRQ Steering to Get IRQ TABLE using ACPI BIOS, while unchecking all others.
For some others unchecking the Get IRQ TABLE from Realmode PCIBIOS 2.1 Call, while leaving all other options as they where did the trick.
Assign IRQ for your Video Adapter
Another fix that worked for some people is to go in your systems BIOS, and assign an IRQ for your Video Adapter (you might not have this option in your BIOS). This also solves problems with not being able to Restart in MS-DOS mode.
