Flash the device driver into the BIOS:

Using the REFLASH.EXE (version 2.0+) utility provided on the diskette, issue the

following command:

REFLASH /F=PICOFA.BIN /O=4C000

[Note: This step is only necessary if the FBD was changed. The EPC-30 comes

default from the factory with this extension installed.] When this process successfully

completes, the Picoflash device driver will have been transferred into the 16KB area

of memory from 0x4C000 - 0x4FFFF.

Inform the setup menu of how to load the extension:

Now reboot the machine and go into setup (by hitting the F2 key at boot time), and

enter the ‘Embedded Features’ menu. In this menu, one of the three Embedded

Shadow Regions, specify the “Offset of BIOS extension in FBD” as 0x4C000, and

the BIOS extension size as 04000.

Next, the “Destination Address” needs to be specified. Depending on your particular

system configuration, this address may vary. The BIOS extension uses a 16KB I/O

window from 0xD4000 to 0xD7FFF. If there are no other extensions installed, use

0xD8000 as your “Destination Address” which will load the BIOS extension into the

16KB window from 0xD8000 to 0xDBFFF.

Final reboot:

Finally, now that the BIOS extension is properly flashed, and the BIOS setup menu

knows how to position it, reboot the machine one more time. During this next boot

cycle, the BIOS extension for the Picoflash should be loaded at 0xD8000.

Step 2: Format the drive

Assuming that the driver loaded successfully (either as a device driver or as a BIOS

extension), run the PFORMAT.EXE utility as follows:

PFORMAT D: /C /V

The /C confirms the format, and the /V switch says to put a volume label on the drive.

When the format completes, give the drive a volume label. This should complete the

process of making the RFA into a Flash File System. If you are going to use the RFA

as a bootable device, the system must be transferred to the RFA device. This can be

done by using the DOS 'SYS' command.

The RFA should now be set up for use as a DOS Flash File System. The standard

DOS copy, delete, and other utilities for file creation/modification should function

correctly.
