8.1BIOS Upgrade and Recovery

To reprogram the BIOS or update it if it becomes corrupted, use the DTIFLASH.EXE utility available from DTI and discussed later in this chapter.

8.1.1 Flash Utility Program

DTIFLASH.EXE is a utility program that can be obtained from DTI in the event a BIOS should be updated. Run DTIFLASH.EXE to modify the BIOS in the on-board flash memory. DTIFLASH.EXE eliminates the need for a PROM programmer and for removing boards and chips from the system.

To reprogram the BIOS , you should do the following:

1)The latest flash will be distributed via a Customer Service Alert Notification. Normally, the BIOS zip file also contains the DTIFLASH.exe utility you need.

2)Create a DOS 6.2 boot disk and add the BIOS file and flash utility to the disk. Usually other Windows* boot disks will work fine as well, but use DOS if you run into any problems.

3)Boot the board from the DOS boot disk you just created. You can do this via a USB Floppy. If your system does not boot off the floppy you may need to enter the BIOS setup in order to move the floppy to the first item in the boot order.

4)Use the following syntax at a DOS prompt:

DTIFLASH

The BIOS zip file should also contain a Readme file or installation file to help guide you through BIOS installation.

8.1.2 BIOS Recovery

In the event that the contents of the BIOS ROM are corrupted, there is a mechanism to recover the BIOS Rom using the BIOS bootblock code.

To reprogram corrupted BIOS, you should do the following:

1)The latest flash will be distributed via a Customer Service Alert Notification.

2)Format a disk and copy only the BIOS ROM file to the disk.

3)Power on the board with the disk installed.

4)Press CTRL+HOME keys during power on. The board will enter automatic update mode and program the file from the disk. There will be no video displayed, but activity should be seen on the disk and the POST LEDs.

5)The board will automatically reboot after complete.

8.2BIOS Configuration Overview

This topic presents a brief introduction to the DTI Embedded BIOS.

The DTI BIOS Software supports all of the IBM /AT standard functions and several functions and features. Features of the DTI BIOS include built-in utilities, help windows, and system monitoring functions.

Upon initial power up or after a hardware reset, the processor begins executing code out of the onboard BIOS. The BIOS contains all of the software needed to boot the board to a working state so an operating system can be loaded. The first order of business for the BIOS is to initialize crucial system components, such as timers and chipset parts. The BIOS then performs basic components checks to ensure their presence and then sets them to a default state. Next, the cache and memory controllers must be initialized and configured for the type and configuration of the cache and memory found in the system.
