Functional Architecture
3.4.1.9
The resource manager assigns the PIC-mode interrupt for the devices that will be accessed by
the legacy code. The BIOS ensures the PCI BAR registers and the command register for all
devices are correctly set up to match the behavior of the legacy BIOS. Code cannot make
assumptions about the scan order of devices or the order in which resources will be allocated to
them. The BIOS supports the INT 1Ah PCI BIOS interface calls.
3.4.1.10
The BIOS automatically assigns IRQs to devices in the system for legacy compatibility. No
method is provided to manually configure the IRQs for devices.
3.4.1.11
The option ROM support code in the BIOS dispatches the option ROMs in available memory
space in the address range 0c0000h-0e7fffh and follows all rules with respect to the option
ROM space. The BIOS integrates option ROMs for the Intel
Controller, Marvell* 88E8050 Network Interface Controller, and the ATI* Rage XL Video
Controller.
3.4.1.12
The system BIOS supports the INT 1Ah, AH = B1h functions as defined in the PCI BIOS
Specification. The system BIOS supports the real mode interfaces and does not support the
protected mode interfaces.
