6.4.5 Combination of ROM and RAM Disk
The AR-B1462 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-B1462 is configured as a ROM and a RAM
disk. You don’t need to copy DOS onto the RAM disk.

(1) DiskOnChip Hardware Installation

Step 1: Make sure the target platform is powered OFF
Step 2: Use JP7 to select the correct D.O.C. socket.
Step 3: Plug the DiskOnChip device into the MEM4 socket. Verify the direction is correct (pin 1 of the
DiskOnChip is aligned with pin 1 of the MEM4 socket)
Step 4: Line up and insert the AR-B1462 card into any free slot of your computer.
Step 5: Power up the system
Step 6: During power up you may observe the messages displayed by the DiskOnChip when its drivers are
automatically loaded into system’s memory
Step 7: At this stage the DiskOnChip can be accessed as any disk in the system
Step 8: If the DiskOnChip is the only disk in the system, it will appear as the first disk (drive C: in DOS)
Step 9: If there are more disks besides the DiskOnChip, it will appear by default as the last drive, unless it
was programmed as first drive.
Step 10: If you want the DiskOnChip to be bootable, copy the operating system files into the DiskOnChip by
using the standard DOS command.
