Appendix F: Re-programming the flash chip
107
Using jumpers to re-program the flash chip
1. Install the force recovery jumper:
A. Turn system power off, then remove the EPC-3305 from the CompactPCI
chassis.
B. Locate the BIOS configuration jumper block and connect the appropriate pins:
i. To re-program the BIOS or the FBD, connect the Force BIOS Recovery pins:
ii. To re-program the Boot Block, you must also connect the Boot Block
Write Enable pins:
2. Re-program the flash chip:
A. Insert the Flash Boot diskette into the floppy drive.
B. Power up the EPC-3305. The phlash.exe program automatically runs and
re-programs the flash chip.
C. Remove the Flash Boot diskette from the drive when the drive stops
accessing the disk.
3. Remove the force recovery jumper and return the system to normal operation:
A. Turn system power off.
B. Locate the BIOS configuration jumper block and disconnect the Force BIOS
Recovery pins and, if you connected them, 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.
Determining when disk access has stopped is difficult. Typically, the
disk drive makes anywhere from 15–30 accesses, then stops making
access sounds for about 5 seconds. At this time you should remove
the disk.
If disk access sounds resume, the re-program process is repeating.
Wait until disk access again stops, then remove the disk.
