Assuming a modern system board, beginning
with Windows 95B (not Windows 95 Release 4.00) a new feature called
PCI steering was introduced. For example: An ISA sound card uses IRQ
9. You install a PCI card that would like to use IRQ 9.
PCI Steering will:
- Disable the ISA sound card.
- Reprogram to available IRQ (example IRQ 10) to
be an ISA IRQ.
- Move the Sound card to IRQ 10.
- Assign an IRQ Holder to 9.
- Reprogram IRQ 9 to be a PCI IRQ.
- Install the PCI device to IRQ 9.
The only challenge with PCI Steering
is if one device goes haywire, the whole scheme falls apart like a house
IRQ Steering only works on PCI, not ISA.
This leads us to another expansion
bus, once again, brought to us by Intel.
