Why Plug ’n Play is Sometimes Plug and Pray

Some expansion hardware is designed to emulate a name-brand competitor.

If the BIOS on the expansion hardware masquerades as a name-brand device the Operating System will follow instructions to install the driver of the name-brand expansion card.

Since it wasn't from the name-brand manufacturer, the new device will either exhibit unpredictable behavior, or completely fail.

And sometimes a driver gets corrupt or was simply a piece of junk to begin with.

[spacer]Sharing IRQs

Prior to PCI Version 2.1 all expansion cards needed their own IRQ (if a device was to be used at the same time another device with the same IRQ would be in use). With the release of PCI V.2.1 that is no longer the case. Expansion cards can share IRQs.
