EPC-3307 Hardware Reference
126
Before you begin
•
Ensure that you have the following:
•
Minimum 2 MB of DRAM to run the re-flash program
•
A 3.5" 1.44 MB floppy diskette drive attached to or installed in the system
•
A floppy diskette
•
Access to the RadiSys web site.
•
Decide which portion of your flash chip to re-program:
•
BIOS
: Re-program the BIOS to fix bugs, add new features, and replace a
corrupted BIOS. This is the portion of the flash chip most frequently
updated. You can perform this update whether or not the BIOS can boot the
system.
•
FBD
: Re-program the FBD when you need to re-program all of the flash
chip except the Boot Block. Your flash chip may require this type of update
if code or data structures outside the BIOS area require an update. You can
perform this update whether or not the BIOS or FBD can boot the system.
•
Boot Block
: Re-program only the Boot Block. You will perform this type of
update rarely, if ever.
•
Decide which re-programming process to use:
•
phlash program
: Use this method to re-program the BIOS or FBD from the
DOS command line. RadiSys recommends this as the method that provides
the most feedback during the re-programming process.
•
BIOS configuration
program options
: Use this method if the existing BIOS
runs. RadiSys recommends this as the simplest method.
•
Force recovery jumper
: Use this method when you have physical access to
the board, but no keyboard or monitor, or when the BIOS is corrupt.

If the Boot Block is corrupt and not executable, return the EPC-3307 to
the factory for repair. For information about returning items to RadiSys,
see the RadiSys web site.
This process cannot be performed in a non-DOS OS (for example:
Windows NT, QNX, or LINUX).
Select this process if your system runs a non-DOS OS (for example:
Windows NT, QNX, or LINUX).
