OCPRF100 MP Server System Technical Product Specification

Revision 1.0

the system BIOS provides the run-time functions necessary to boot from an I2O mass-storage adapter card. I2O devices are added to the interrupt 13h chain and booted using these calls.

6.2.3Management

Management of clients and servers is a major issue for end users. The system BIOS supports server management applications through the following specifications:

Desktop Management Interface (DMI) Specification, Version 2.00

System Management BIOS (SMBIOS) Reference Specification, Version 2.1

Wired for Management Baseline Specification, Version 1.1a

The BIOS provides the data and interfaces required by the DMI specification. In addition, the BIOS provides a memory image of DMI data to allow operating systems to read DMI structures from protected-mode.

6.2.4Configuration

Plug and Play compatibility allows most devices to be added to the system with no manual configuration at all. The BIOS supports the following industry standards for full Plug and Play com- patibility:

Multiprocessor Specification (MPS), Versions 1.1 and 1.4

Extended System Configuration Data Specification, Version 1.02a

Plug and Play BIOS Specification, Version 1.0a

Plug and Play ISA Specification, Version 1.0a

PCI Specification, Revision 2.1

PCI BIOS Specification, Revision 2.1

PCI to PCI Bridge Specification, Revision 1.0

PCI Power Management Specification, Revision 1.0

PCI Hot-plug Specification, Revision 1.0

POST Memory Manager (PMM) Specification, Version 1.01

Although the system contains no ISA slots, the Plug and Play ISA Specification is supported because of the embedded peripherals.

The system BIOS can support either version of the Multiprocessor Specification. If version 1.1 is selected, BIOS simply includes entries for the processors, buses, APICs, and interrupts. If version 1.4 is selected, BIOS also creates entries describing the bus, memory, and I/O topology of the system. BIOS Setup allows the user to specify which version of tables should be generated.

The BIOS allows users to use the SSU to specify PIC-mode interrupt assignments. This configuration step is completely optional unless required by higher level software.
