Using BIOS configuration options to re-program the
flash chip
1. If you plan to re-program the Boot Block, connect the Boot Block Write Enable
pins:
A. Turn system power off, then remove the EPC-3305 from the CompactPCI
chassis.
B. Connect these pins:
C. Power up the EPC-3305 and run the BIOS configuration program.
2. Select the Exit and Update BIOS option in the BIOS configuration program’s
Exit menu. The BIOS configuration program instructs the BIOS to run an
update (re-program the flash chip) upon reboot, then terminates and reboots the
system.
3. Re-program the flash chip:
A. Insert the Flash Boot diskette into the floppy drive.
The phlash.exe program automatically runs and re-programs the flash chip.
A. Remove the Flash Boot diskette from the drive when the drive stops
accessing the disk.
4. If you re-programmed the Boot Block, remove the Boot Block write enable
jumper and return the system to normal operation:
A. Turn system power off.
B. Locate the BIOS configuration jumper block and disconnect the Boot Block
Write Enable pins.
C. Replace the EPC-3305 in the CompactPCI chassis.
D. Power up the EPC-3305.
Do not install this jumper unless a Boot Block update is required. A BIOS
boot block rarely changes and seldom, if ever, requires re-programming.
