AR-B1375/AR-B1376 User s Guide

(2) Software Programming

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

Step 7: If 5V FLASH (small page) is being used for the first time.

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.
