ISA devices: Add-in ISA devices are not supported on this platform. However, some standard
PC peripherals may require ISA-style resources – resources for these devices will be reserved as
needed.
Add-in video graphics adapter (VGA) devices: If found, the BIOS initializes and allocates
resources to these devices.
PCI Devices: The BIOS allocates resources according to the parameters set up by the SSU and as
required by the PCI Local Bus Specification, Revision 2.1.
The system BIOS Power-on Self Test (POST) guarantees that there are no resource conflicts prior
to booting the system. Please note that PCI device drivers are required to support the sharing of
IRQs. Sharing IRQs should not be considered a resource conflict. Note that only four legacy IRQs
are available for use by PCI devices; as a result, most of the PCI devices share legacy IRQ’s. In
SMP mode, the I/O APICs are used instead of the legacy “8259-style” interrupt controller. There is
very little interrupt sharing in SMP mode.
PnP ISA Auto-configuration
The system BIOS:

TM
Supports relevant portions of the Plug and Play ISA Specification, Revision 1.0a and the Plug
and Play BIOS Specification, Revision 1.0A.
Assigns I/O, memory, direct memory access (DMA) channels, and IRQs from the system
resource pool to the embedded PnP Super I/O device.
Does not support add-in PnP ISA devices.
