CORE BIOS download function

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 bootdisk.

Is the empty diskspace, where the download tool is located, larger than 64kB (for safe storage)

Start the DOWNLOADING process:
1. Start the system with the bootable diskette. If you do not have a bootable diskette or floppy drive,
you may can start in DOS mode by pressing the F5 key to disable the autoexec.bat and config.sys.
2. Run DELEP520.EXE to clear the CMOS and the EEPROM
IF YOU DO NOT RUN THE DELEP520.EXE, THE SYSTEM WILL BE DESTROYED DURING THE BIOS
UPGRADE!
3. Run Flash520.exe M520xxxx.cor
4. If the bios download is finished you have to power off the system
5. After power on the system, press "Ctrl" + "ALT" + "S" to enter the setup, set the default values and exit
the setup with "save and reboot"
6. Power off the system
7. Now the download procedure is finished
If the download does not work:
Check, if no EMM386 is loaded.
-
Check, if no peripheral card is in the system, which occupies the same memory range. Disconnect this
-
card.
If the download is stopped or not completed, make only a warm boot and repeat the steps or download
-
another file. As the video is may shadowed, everything is visible and a cold boot would clear the screen
and nothing would be visible afterwards.
