Method and system for configuring plug and play devices for a computer operating system

A system for configuring plug and play (PnP) devices by a computer operating system, comprising:

• means for initiating a power on self test within a computer system containing PnP and peripheral component interconnect (PCI) devices;
• means for configuring PnP and PCI devices within said computer system with associated interrupt requests (IRQs);
• means for storing a list of said PnP and PCI devices which are non-bootable;
• means for assigning IRQs to said non-bootable PCI devices;
• means for booting said computer system from a media;
• and
• means for detecting a plug and play operating system for activating and deactivating said PnP devices and said PCI devices depending on a type of said media.

A computer program product, on a computer readable medium, comprising:

• a computer process code for configuring plug and play (PnP) and peripheral component interconnect (PCI) devices within a computer system and assigning associated interrupt request (IRQs) during a power on self test within a computer system;
• wherein said computer process code stores a list of said PnP and PCI devices which are non-bootable;
• wherein in response to assigning IRQs, all said non-bootable PCI devices are assigned an IRQ by transferring assigned said IRQs from said list of PnP devices by removing and deactivating said PnP devices;
• wherein responsive to detecting a plug and play operating system, activating and deactivating said PnP devices and said PCI devices depending on a type of media used for booting.
