STL2 Server Board TPS Basic Input Output System (BIOS)

4.4CMOS Default Override

The BIOS detects the state of the CMOS default switch. If the switch is set to “CMOS Clear” prior to power-on or a hard reset, the BIOS changes the CMOS and NVRAM settings to a default state. This guarantees the system’s ability to boot from floppy.

Password settings are not affected by CMOS clear. The BIOS clears the ESCD parameter block and loads a null ESCD image. The boot order information is also cleared when CMOS is cleared via jumper. The configuration data for the on-board SCSI controllers is not cleared during a clear CMOS event as each device controls its own default settings

If the Reset Configuration Data option is enabled in Setup, ESCD data and BIOS Boot specification data is cleared and reinitialized in next boot.

4.5Flash Update Utility

The BIOS update utility (Phoenix* Phlash.exe) loads a fresh copy of the BIOS into flash ROM. The loaded code and data include the following:

∙On-board video BIOS, network controller BIOS, and SCSI BIOS.

∙BIOS Setup utility.

∙User-definable flash area (user binary area).

∙OEM logo (splash screen).

When running Phoenix* Phlash in interactive mode, the user may choose to update a particular flash area. Updating a flash area takes a file or series of files from a hard or floppy disk, and loads it in the specified area of flash ROM.

Note: The Phoenix Phlash utility must be run without the presence of a 386 protected mode control program, such as Windows* or EMM386*. Phoenix* Phlash uses the processor’s flat addressing mode to update the flash part.

4.5.1Loading the System BIOS

The BIOS update utility (PHLASH) loads a new copy of the BIOS into Flash ROM. The loaded code and data include the following:

∙On-board Video BIOS and SCSI BIOS

∙BIOS Setup Utility

∙Quiet Boot Logo Area

When running PHLASH in interactive mode, the user may choose to update a particular Flash area. Updating a flash area loads a file or a series of files from a hard or floppy disk into the specified area of Flash ROM.
