It is very easy to use the RAM disk. The RAM disk operates just like a normal floppy disk. A newly installed RAM
disk needs to be formatted before files can be copied to it. Use the DOS command [FORMAT] to format the RAM
disk.
Step 1:
Use jumper block to select the memory type as SRAM refer.
Step 2:
Select the proper I/O base port, firmware address and disk drive number on SW1.
Step 3:
Insert SRAM chips into sockets starting from MEM1
Step 4:
Turn on power and boot DOS from hard disk drive or floppy disk drive.
Step 5:
Use the DOS command [FORMAT] to format the RAM disk. If you are installing SRAM for the first
time.
To format the RAM disk and copy DOS system files onto the RAM disk.
C:\>FORMAT [RAM disk letter] /S /U
To format the RAM disk without copying DOS system files into the RAM disk.
C:\>FORMAT [RAM disk letter] /U
Step 6:
Use the DOS command [COPY] to copy files onto the RAM disk. For example, if you want to copy file
<EDIT.EXE> to the RAM disk from drive C: and the RAM disk is assigned as drive A:.
COPY C:EDIT.EXE A:
NOTE: In addition, you can use any other DOS command to operate the RAM disk.
6.4.5 Combination of ROM and RAM Disk
The AR-B1375/AR-B1376 can be configured as a combination of one ROM disk and one RAM disk. Each disk
occupies a drive unit.
Step 1:
Use jumper block to select the proper ROM/RAM configuration you are going to use.
Step 2:
Insert the first programmed EPROM into the socket mem1, the second into the socket MEM2, etc.
Step 3:
Insert the SRAM chips starting from the first socket assigned as SRAM.
Step 4:
Select the proper I/O base port, firmware address and disk drive number on SW1.
Step 5:
Turn on power and boot DOS from hard disk drive or floppy disk drive.
Step 6:
Use the DOS command [FORMAT] to format the RAM disk.
C:\>FORMAT [RAM disk letter] /U

And then use the DOS command [FORMAT] to format the FLASH disk.
Step 8:
If large page 5V FLASH is being installed for the first time, please use the FLASH programming utility
RFG.EXE to program ROM pattern files.
NOTE: Users can only boot DOS from the ROM disk drive if the AR-B1375/AR-B1376 is configured as a ROM and
a RAM disk. You don’t need to copy DOS onto the RAM disk.
