Reflashing the Flash Boot Device

Page D-13

The EPC-30 boot block XModem serial communication requires a straight-

through serial connection to the external host computer and operates at the

auto-detected baud rate with no parity, eight data bits, and 1 stop bit.

Cabling between the host and the EPC-30 may be dictated by the SCP.

However, the only RS-232 signals required by the EPC-30 are Tx, Rx, and

Gnd.

When to Reflash the FBD

Reflashing the FBD is necessary in only two instances:

1. To accomplish a flash update

This instance assumes that the system can successfully boot to an operating

system, such as DOS. This instance also assumes a valid and executable

FBD structure.

2. To accomplish a flash recovery

This instance assumes a corrupt FBD structure, resulting in an unsuccessful

attempt to boot to an operating system. This instance further assumes that the

boot block, containing the recovery code, is not corrupt.

Before You Begin

USE EXTREME CAUTION WHILE REFLASHING

THE FBD. POWERING DOWN OR RESETTING THE

EPC-30 DURING A REFLASHING PROCESS WILL

CORRUPT THE FBD. POWERING DOWN OR

RESETTING THE EPC-30 DURING BOOT BLOCK

REFLASHING WILL REQUIRE FACTORY

REPAIRS.

Before you update the FBD, you should have the following items ready for

use:

• EPC-30 diskette containing reflashing programs REFLASH.EXE and

READ.ME files containing current information about the reflashing

software. The diskette also includes EPC-30 video and system BIOS images.

If you believe there may be updated software, check the RadiSys Web site or

contact RadiSys Technical Support using the information shown on the

cover of this manual for the most current EPC-30 BIOS images.
