PC Card Interface
The EPC-30 supports use of flash or ATA PC cards as Chapter 2 discusses. Many of
the supported PC card configurations require the use of appropriate card and socket
services software to provide PC card slot drivers and a suitable format for the card.
This appendix briefly describes the PCM+ Card and Socket Services software from
Phoenix Technologies, Ltd. and provides a summary of PC card interfaces. RadiSys
has tested the EPC-30 interface with ATA PC cards using this software.
A read/write interface between the EPC-30 and a flash PC card requires optional
Flash File System software. The PCM+ utilities can configure only I/O PC cards. This
does not include flash PC cards. RadiSys has tested the EPC-30 flash PC card
interface using Flash File System software from M-Systems Flash Disk Pioneers, Ltd.
and Cardsoft, Inc.
Refer to the documentation from Phoenix included with the EPC-30 diskettes for
more information.
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.
PICOFA.SYS - The device driver.
PFORMAT.EXE - The format utility.
DOS format utility will not work for the RFA.
PICOFA.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=PICOFA.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.
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.
