Step 1B (Load as BIOS extension)
Note that if the driver is loaded as a BIOS extension, the system will attempt
to boot from the device. This means that the RFA must be formatted and
loaded with system files before the driver can be successfully loaded as a
BIOS extension.
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=PFA2.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.
