Updating the BIOS

The jumper on J2C1 pins 4(B-C) applies +12 V power to the VPP pin on the flash memory device.
This allows you to update the BIOS in flash memory with the Flash Update Utility. Moving the
jumper to pins 4(A-B) protects the contents of flash memory.
✏NOTE

diskette, contact your dealer or sales representative.
Before you can update the system BIOS from the Flash Update Utility diskette, you must make the
diskette MS-DOS bootable. You must have either MS-DOS version 5.00 or 6.00 (or greater)
installed on C:\DOS. To prevent accidentally installing a BIOS for a different type of system, the
update utility insures that the BIOS matches the target system.

Please review the update utility instructions and the release notes distributed
with the update utility and BIOS code before attempting to update the BIOS.
The BIOS update utility allows you to update the
