5.7. BIOS
5.7.1.
Core BIOS download
5.7.1.1. Before downloading a BIOS
Please read through this section carefully and prepare for the download.
Make a bootable diskette which includes the following files:
Flashrom.com
core BIOS xxxxxxxx.yyy
Important...
Do not use boot disks created in a Windows operating system. If you do not have an MSDOS
6.22 disk available, you can download a boot disk from www.bootdisk.com.
NOTE:
Select the SHADOW option in the BIOS, for a BIOS and VGA (if this option is available).
Disable the EMM386 or other memory managers in the CONFIG.SYS of your boot disk.
Make sure that the Flashrom.com program and the BIOS to download are on the same path and
directory!
Boot the DOS without config.sys and autoexec.bat
Check, where the Flashrom.com is located, that the available disk space is larger than 64kB (for safe
storage).
Make sure the floppy disk is not write-protected.
5.7.1.2. Start the download
1.
Start the system with the bootable diskette. If you do not have a bootable diskette or floppy drive,
you can start in DOS mode by pressing the F5 key to disable autoexec.bat and config.sys.
2.
Run Flashrom.com.
(In some cases you have to try the following: FLASHROM /D /sFFFC0000 biosname.xxx)
3.
Power off the system.
After powering on the system, press F1 to enter setup and set the default values; then "save and
leave" the setup.
4.
Switch off the system after the download is finished.
5.7.1.3. If the download does not work:
Check, if the EMM386 is not loaded.
Check if there is a peripheral card in the system, which would occupy the same memory range. If one
is present, disconnect it.
If the download stopped or did not finish, make a warm boot* and repeat the steps or download
another file. (* As the video is shadowed, everything is visible and a cold boot would clear the screen
so nothing would be visible afterwards.)
Attention!
NEVER UPDATE A BIOS WITH A USB MEMORY STICK!!
THE SYSTEM WILL CRASH DURING THE DOWNLOAD!
Only use a USB or a standard floppy
Also, if you have two IDE devices attached to the board (e.g. HDD and CD-ROM), disconnect
the CD-ROM before downloading the BIOS.
