Title:   Boot Block Recovery Procedure for Micronics M54Hi Motherboard

Summary:  Instructions for boot block recovery procedure used to
          replace BIOS in flash chip on Micronics M54Hi motherboard.
======================================================================

The Micronics M54Hi motherboard is identified by the Micronics
part number 09-00236 silkscreened onto the front right corner of the
board. The original BIOS version on this motherboard is Phoenix
4.04 M54Hi-xx[xx] (other OEM versions and upgrades may exist).
The Micro Firmware BIOS upgrade for this board is Phoenix 4.05.xx
M5HS10.

The boot block recovery code resides in a protected area of the flash
chip. This code checks for a working BIOS on every boot and will only
attempt to install a BIOS from diskette if the BIOS in the flash chip
is corrupt or missing. A black screen on powerup may indicate the
absence of a working BIOS in the flash chip.

This procedure requires a valid recovery disk, normally created during
installation of a flash BIOS upgrade. A BIOS recovery disk for this
motherboard is available on our FTP site. The filename is M54HIRD.EXE.
This is a self-extracting ZIP file containing a self-extracting
diskette image, a README file, and this file. This recovery disk will
program the flash chip with Phoenix 4.04 M M54Hi-10PM.

Boot Block Recovery Procedure:

1. Turn system off.

2. A jumper must be installed on W11 to enable writing to the flash
   chip. (This jumper may already be installed and must be left
   installed if using a PnP BIOS). Do not move the boot block recovery
   jumper (W10). W10 should remain on pins 2-3. (This jumper would be
   used with an older type of boot block code, which was not used on
   this motherboard).

3. Insert recovery disk.

4. Turn system on. After 10 or 15 seconds, the speaker will sound one
   long and two short beeps. The display screen will remain blank.
   The diskette drive light will come on, the speaker will sound one
   more beep. In about 30 seconds, there will be four beeps to
   indicate that the process is finished.

5. Power system off and back on. The BIOS signon text should display.
   It will probably be necessary to enter CMOS setup and adjust
   setup values.
.
Some video cards (ISA or PCI) may prevent the boot block recovery
procedure from working. If there are no beeps and the diskette drive
is not accessed, it may be necessary to remove a video card. The boot
block procedure will work without a video card.
