PCI Steering
Starting with Windows 95b (not the
initial release of the OS) and OSR1, BIOS gained the ability to assign
IRQs to devices. With OSR2 enabled, Windows 95 gained the ability to
assign IRQs. This is known as PCI bus IRQ steering or PCI steering.
Although with OSR2, Windows has the ability to assign the IRQs, those
assignments are still typically made by the BIOS and Windows rarely
overrides those assignments. Remember, this only works with the PCI
bus. ISA has no steering capacity.
