SECTION 4 - USING THE PROMDISK-CHIP DISK EMULATOR
The IRV-3702 SBC includes a 32-pin socket that supports the MCSI PROMDISK-Chip disk emulator
which operates as a Read/Write fixed disk drive. The paragraphs that follow describe how to use the
optional PROMDISK-Chip.
USING ROM-DOS AND OTHER DISK OPERATING SYSTEMS
The PROMDISK-Chip has been pre-configured at the factory with the latest version of the Datalight
ROM-DOS disk operating system. In addition, a current copy of the operating system is supplied on a
floppy diskette.
If the operating system is accidentally erased from the PROMDISK-Chip it may be restored using the
SYS command. The DOS format utility should not be used to restore the operating system.
To change the operating system version or type you should simply use the equivalent DOS SYS
command to transfer the operating system.
PROMDISK LOW LEVEL FORMAT
The Flash memory contained on the PROMDISK-Chip board was initialized with the Datalight
CardTrick low level format at the factory. During normal operation the Flash memory should never
require reformatting unless there is a serious hardware or software malfunction. In the event it has
been determined that the low level format is corrupted, proceed as follows:
1. At the DOS prompt, run the PROMDISK-Chip low-level format utility PDCFMT.EXE located on the
distribution diskette in the PDCHIP3 subdirectory.
2. Install a bootable floppy diskette in drive A and boot the system.
3. At the DOS prompt type SYS C: to transfer a bootable copy of DOS to PROMDISK-Chip.
4. Remove the floppy diskette from drive A: and reboot the system from PROMDISK-Chip.
CAUTION: Do Not use the DOS Fdisk utilities on the PROMDISK-Chip.
