BIOS Upgrades

Flash memory makes distributing BIOS upgrades easy. A new version of the BIOS can be installed from the hard disk, network or through a serial port.

The disk-based Flash upgrade utility, PHLASH.EXE, ensures the upgrade BIOS extension matches the target system to prevent accidentally installing a BIOS for a different type of system.

Setup Utility

The ROM-based Setup utility permits the system configuration to be modified without opening the system for most basic changes. The Setup utility is accessible only during the Power-On Self Test (POST) by pressing the <F2> key after the POST memory test has begun and before boot begins. A prompt may be enabled that informs users to press the <F2> key to access Setup.

Note: An external alphanumeric keyboard is recommended for running the BIOS CMOS Setup Utility. Otherwise, a Touch Screen can be used.

Plug and Play

The Processor BIOS also has a setup option to support the Windows runtime plug and play utilities. When this option is selected, only devices critical to boot are assigned resources by the BIOS. Device Node information is available for all devices to ensure compatibility with Windows 95. System configuration information is stored in ESCD format. The ESCD data is cleared upon loss of the CMOS voltage.

Advanced Power Management

The Processor BIOS has support for both 1.1 and 1.2 Advanced Power Management (APM). The version of APM drivers loaded in the operating system by the user determines what specification the BIOS adheres too. In either case the energy saving Standby mode can be initiated by a keyboard hot key sequence or a time-out period set by the user.
