Appendix D -
PFormat
The EPC-5A supports use of EXM-2A flash cards as Chapter 2 discusses. The
supported configurations require the use of appropriate software to provide drivers
and a suitable format. This appendix briefly describes the software from RadiSys.
The following is a description of how to bring the RFA up using the PICOFA driver.
Contents of the distribution diskette:
CONFIG.SYS - A sample configuration.
PFA2.SYS - The device driver.
PFORMAT.EXE - The format utility.
PFA2.BIN - The BIOS extension.
REFLASH.EXE - Utility to flash the BIOS extension.
Step 1: Load the driver (This can be done either as a BIOS extension or as a
device driver).
Step 1A (Load as device driver)
Add the line "DEVICE=PFA2.SYS" to your CONFIG.SYS file.
The jumpers on the board for linear/paged mode and byte/word access to the
RFA should be set to byte mode and paged I/O in the BIOS setup menus.
Reboot the system. The driver will load and echo out a message that says
which DOS device has been assigned to the RFA. If the setting is not right,
the driver will echo a message stating the required RFA mode settings.
