====================================================================== Title: Boot Block Recovery Procedure for Intel Classic R Motherboard ---------------------------------------------------------------------- Filename: INTELREC.TXT WWW URL: http://www.firmware.com/pb4ts/intelrec.htm FTP URL: ftp://ftp.firmware.com/text/intelrec.txt Author: Terry Slade, Micro Firmware Technical Support Revision: 03/30/98 Summary: Instructions for boot block recovery procedure used to replace BIOS in flash chip on Intel Classic R motherboard. ====================================================================== The Intel Classic R motherboard can be identified by the Intel part number 612194-00x, silkscreened onto the front right corner of the board. The original BIOS supplied by Intel is Phoenix A486 1.00.0x.AC0 (the newest version is 1.00.09.AC0, dated 03/31/94, which is supplied on our recovery disk). The Micro Firmware upgrade BIOS is Phoenix 4.03.6.xx I4GS10 or Phoenix 4.05.xx I4HS10. The boot block procedure is normally used if there no BIOS code in the flash chip (usually resulting in a black screen on poweron). The procedure requires a valid recovery disk, normally created during installation of a flash BIOS upgrade. We can supply a recovery disk if needed. The file INTELRD.EXE contains a self-extracting diskette image of a recovery disk. This file is available on our web site at http://www.firmware.com/fbr.htm . This file is also available on our FTP site at ftp://ftp.firmware.com/recovery/intelrd.exe and on our BBS. If there is a working BIOS present, the system can also be booted from this diskette to flash the BIOS on this diskette into the flash chip. . 1. Turn system off 2. Move boot-block jumper J13 to pins 2-3 You may also need to move the flash chip write-protect jumper, J12 Pins 1-2 enable write, pins 2-3 prevent writing to flash chip 3. Insert recovery disk (created when installing new BIOS) 4. Turn system on In 15 or 20 seconds, diskette drive light will come on. 20 or 30 seconds later, speaker will beep once. Diskette access light will remain on, there will be nothing on the display screen. When process is finished (30 to 60 seconds) the speaker will beep twice to indicate process is finished. Diskette light may remain on. 5. Turn system off, remove diskette. 6. Move jumper J-13 back to pins 1-2 It is recommended to move jumper J12 to pins 2-3 to protect the flash chip against accidental erasure. NOTE - if using our BIOS upgrade I4HS10, J12 must be left on pins 1-2 so that the ESCD can be updated. 7. Turn system on, setup CMOS . 4 long low beeps indicates that no diskette is in the drive or that the diskette drive is not installed properly. If any diskette besides a valid recovery disk is used, nothing will be done. # ====================================================================== Micro Firmware Technical Support ---------------------------------------------------------------------- Voice 405-321-8333 email support@firmware.com Fax 405-321-8342 WWW http://www.firmware.com BBS 405-573-5538 FTP ftp://ftp.firmware.com ====================================================================== (C) 1996-1998 Micro Firmware, Inc.
