A method and system are disclosed for configuring PnP devices for a computer operating system by initiating a power on self test (POST) within a computer system fo r configuring PnP and PCI devices. During the process of configuring PnP and PCI devices, a list i s composed of devices that are not absolutely necessary for booting the system (e.g. modem or ethernet controller). While the PCI devices are configured, if the system has no usable IRQ's, POST take s one from a nonessential PnP ISA (Industry Standard Architecture) device in the list, an d gives it to the PCI device. The POST operation searches for the presence of a PnP operating syst em option while progressing through the startup sequence (of bootable media), and activates or deactivates all devices, depending on the type of media being attempted. If the medium is th e hard disk (where the PnP operating system option resides), all of the PnP devices in the list are deactivated. If the medium is any other type (where a PnP operating system option is not likely to reside) the devices are activated.
