Reflashing the Flash Boot Device

Reflashing Processes
The boot block will set the RFA for Linear Mode and Byte-wide Access in
case the RFA reflash is invoked during serial recovery.
To use REFLASH.EXE under DOS, the BIOS settings for the RFA must be
set to Linear Mode and Byte-wide Access. Newly flashed images are not
immediately effective; you must reboot the system as soon as reflashing is
completed.
The EPC-30 must be equipped with at least 2 MB of DRAM in order to
perform the flash update process.
Flash Update Process
You can perform the flash update process only if the EPC-30 is
capable of booting DOS and is equipped with at least 2 MB of
DRAM. Use the RadiSys reflashing software consisting of the
program REFLASH.EXE. The REFLASH.EXE program
manages this self-hosted reflashing process.
You will need to create a bootable floppy disk, then copy over the
REFLASH.EXE program from the EPC-30 utilities diskette set.
You must also copy to the floppy disk the BIOS image files you
will use to reflash the FBD. These image files must be in absolute
binary format (.BIN). Set your system BIOS options to boot from a
floppy.
NOTE: The REFLASH.EXE program uses protected mode access
routines. Run this program from DOS only.
Using REFLASH.EXE is the preferred method for installing BIOS
extensions.
REFLASH.EXE erases and updates the blocks of the FBD
specified on the command line. Specify the file to flash by using the
/F=<filename> and the FBD offset at which to begin flashing by
using the /O=<offset> command line parameters. Figure D-1 shows
each FBD segment address. For example, REFLASH.EXE
/F=[filename] /O=0 begins the flash update process without an
address offset. The program requires both of the command line
parameters. To view the command line parameters on the screen,
type REFLASH.EXE with no parameters.
