2.4.5 Legacy Option ROM Support

The legacy support code in the BIOS will dispatch the legacy option ROMs in the available

memory space in the address range 0C0000h-0DFFFFh and will follow all the legacy rules with

respect to the option ROM space. If room is available in the E segment, and both C and D

segments are already used, the BIOS will also shadow up to 0E7FFF. The BIOS allows the user

to disable the shadowing of the onboard PCI devices.

2.4.6 EFI PCI APIs

The BIOS provides standard PCI protocols as described in the Extensible Firmware Interface

Reference Specification, Version 1.1.

2.4.7 Legacy PCI APIs

In legacy mode, the system BIOS will support the INT 1Ah, AH = B1h functions as defined in the

PCI BIOS Specification, Revision 2.1. The system BIOS supports the real mode interface.

2.4.8 Dual Video

The BIOS supports single and dual video modes. Dual video mode is disabled by default.

 In single video mode, the onboard video controller is disabled when an add-in video card

is detected.

 In dual video mode, the onboard video controller is enabled and is the primary video

device. The external video card is allocated resources and is considered the secondary

video device.

Note: See the server or workstation Technical Product Specification that applies to your

product for more information.

2.4.9 Parallel ATA (PATA) Support

The integrated IDE controller of the Intel

631xESB / 632xESB I/O Controller Hub ICH6

provides one IDE channel. This IDE channel can support one optical drive. The IDE channels

can be configured and enabled or disabled by accessing the BIOS Setup Utility during POST.

The BIOS supports the ATA/ATAPI Specification, version 6. It initializes the embedded IDE

controller in the chipset south-bridge and the IDE devices that are connected to these devices.

The BIOS scans the IDE devices and programs the controller and the devices with their

optimum timings. The IDE disk read/write services that are provided by the BIOS use PIO

mode, but the BIOS will program the necessary Ultra DMA registers in the IDE controller so that

the operating system can use the Ultra DMA modes.

The BIOS initializes and supports ATAPI devices such as LS-120/240, CD-ROM, CD-RW, and

DVD-ROM drives.
