Title:    Boot Block Recovery Procedure for Intel Zappa Motherboard
----------------------------------------------------------------------

Summary:  Instructions for boot block recovery procedure used to
          replace BIOS code into flash chip on Intel Zappa
          motherboard.
======================================================================

The Zappa motherboard is a Socket 5 Pentium PCI board with the Intel
Triton chipset (82437FX, 82438FX x2, 82371FB). This board was used
by Gateway 2000 and other vendors. The BIOS suffix is BS0[x]. On
Gateway 2000 systems the BIOS suffix is BS0T.

The boot block procedure is normally used only if there no BIOS code
or invalid BIOS code in the flash chip, normally resulting in a blank
screen at poweron. This procedure may also be needed if the wrong BIOS
has been flashed into the system.

The procedure requires a valid recovery disk, normally created during
installation of a flash BIOS upgrade. A recovery disk for this
motherboard is available on our web site at:
http://www.firmware.com/fbr.htm
and from our FTP site at:  ftp://ftp.firmware.com/recovery

A recovery disk can also be created by downloading the 1.00.xx.BS0T
BIOS from Gateway 2000's web site and copying the files contained in
the archive onto a bootable diskette.
.
1.  Turn system off

2.  Move boot-block jumper J1K1 (labeled NORM and REC) to pins 2-3.
    This jumper is located at the back left corner of the motherboard.
    (This jumper block actually has 6 pins - the 3 pins to the left
    are the recovery jumper).

3.  Insert recovery disk.

4.  Turn system on.
    In a few seconds, the diskette drive light will come on.
    A few seconds later, the speaker will beep once or twice.
    Diskette access light will remain on, there will be nothing on
    display screen.
    When process is finished (30 to 60 seconds) the speaker will beep
    twice (if using Intel recovery disk) or 4 times (if using Micro
    Firmware recovery disk) to indicate process is finished.

5.  Turn system off, remove diskette. (If diskette is left in drive and
    allowed to boot - the flash chip will be wiped out and process must
    be repeated.)

6.  Move jumper J1K1 back to pins 1-2

7.  Turn system on, setup CMOS.
