board uses Intel BIOS, which stored Flash EEPROM upgraded using floppy disk-based program. addition Intel BIOS, Flash EEPROM also contains Setup program, Power-On Self Tests (POST), 1.2, auto-configuration utility, Windows ready Plug Play. This board also supports BIOS shadowing, allowing BIOS execute from 64-bit on-board write-protected DRAM. BIOS displays sign-on message during POST identifying type BIOS five-digit revision code. initial production BIOS board will identified 1.00.01.DH0.

Flash memory makes distributing BIOS upgrades easy. version BIOS installed from diskette. BIOS upgrades available down loaded from secure section Intel bulletin board, Intel's site. disk-based Flash upgrade utility, FMUP.EXE, three options BIOS upgrades: Flash BIOS updated from file disk; current BIOS code copied from Flash EEPROM disk file backup event that upgrade cannot successfully completed; BIOS Flash device compared with file ensure correct version installed.
upgrade utility ensures upgrade BIOS extension matches target computer prevent accidentally installing BIOS different type computer.
local connectors with independent channel support setup automatically BIOS user selects "Autoconfiguration" Setup. interface supports Mode Mode hard drives recognition ATAPI CD-ROMs, tape drives, other ATAPI devices. BIOS will determine capabilities each drive configure them optimize capacity performance. high capacity hard drives typically available today, drive will automatically configured Logical Block Addressing (LBA) maximum capacity Mode depending capability drive. Mixing drives, same cable, that offer different transfer modes supported. Each drive's mode supported independently. user able override auto-configuration options using manual mode setting.
auto-configuration utility operates conjunction with Setup program allow insertion removal cards computer without user intervention (Plug Play). When computer turned after adding add-in card, BIOS automatically configures interrupts, space, other parameters. interrupts distributed available interrupts that have been been assigned card other resource. Those interrupts left "available" Setup will considered free add-in card use. nondeterministic which interrupt will assigned which IRQ. Auto-Configuration function complies with version 2.10 BIOS specification. Computer configuration information stored ESCD format. ESCD data cleared setting CMOS clear jumper Clear position. specification add-in card auto-configuration also part Plug Play BIOS. Peer-to-peer hierarchical Bridge supported, using supplied option TSR, PCI-to-PCMCIA bridge capability possible well.
BIOS incorporates Plug Play capabilities delivered Plug Play Release 1.0A (Plug Play BIOS 1.0A, ESCD 1.03). When used conjunction with Configuration Utility (ICU) Windows 3.x, BIOS allows auto-configuration Plug Play cards, cards, resource management legacy cards. Because BIOS supports configuring devices across bridges, release 1.41 greater must used with board properly view change BIOS settings. Computer configuration information stored ESCD format.
