====================================================================== Title: Boot Block Recovery Procedure for Micronics M54Pi Motherboard ---------------------------------------------------------------------- Filename: M54PIREC.TXT URL: http://www.firmware.com/pb4ts/m54pirec.htm Author: Terry Slade, Micro Firmware Technical Support Revision: 12/23/96 Keywords: recovery, boot block, M54Pi, M5HS60 Summary: Instructions for boot block recovery procedure used to replace BIOS in flash chip on Micronics M54Pi motherboard. ====================================================================== The Micronics M54Pi motherboard is identified by the Micronics part number 09-00208 silkscreened onto the back left corner of the board. The original BIOS version on this motherboard is Phoenix 4.03 or 4.04 M54Pi-N xx[xx] (other OEM versions and upgrades may exist). The Micro Firmware BIOS upgrade for this board is Phoenix 4.05.xx M5HS60. 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 BBS, FTP site, or web site. The following files contain self-extracting diskette images of recovery disks for the following BIOSes: . 5P03RD.EXE 4.03 M54Pi-N 03 no PS/2 mouse, no PnP 5P10PRD.EXE 4.04 M54Pi-N 19P PS/2 mouse, Intel PnP 5P19PMRD.EXE 4.04 M54Pi-N 19PM PS/2 mouse, Intel PnP 5P21RD.EXE 4.04 M54Pi-N 21 newest, Intel PnP, no PS/2 mouse The 19PM version has reserved IRQ11 in the ESCD to help with PnP on Micron systems using a SCSI CD-ROM interface at IRQ11. ---------------------------------------------------------------------- Boot Block Recovery Procedure: 1. Turn system off. 2. A jumper must be installed on JP9 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 (JP7). JP7 should remain on pins 1-2. (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 15 to 25 seconds, the speaker will sound one beep and the following text will display onscreen: Installing BIOS from Recovery Disk. When this process is finshed the diskette drive light will turn off and the system will beep 4 times. You will then need to remove the Recovery Disk from the drive and power off or press the Reset switch to restart your computer. Do you wish to continue? (Y/N). In about 30 seconds the four beeps will sound and the ssytem can be reset. 5. It will probably be necessary to enter CMOS setup and adjust setup values. . PCI video cards will not display any video during the boot block recovery procedure since the boot block code is not elaborate enough to initialize them. Assuming that the boot block recovery procedure is sucessful, video will return when the system reboots. Many 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. The recovery disks that we provide are bootable and can also be used just to install a different BIOS version. ====================================================================== 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 Sales 800-767-5465 CIS GO PCVEND Section 8 ====================================================================== (C) 1996 Micro Firmware, Inc.
