Summary: Information on M5HS10 BIOS upgrade, for the Micronics M54Hi
motherboard, including Setup options and motherboard jumper
and switch settings.
This text file contains information on the Micro Firmware BIOS upgrade part number M5HS10, which is for the Micronics M54Hi (Elan) motherboard, identified by the Micronics part number 09-00236 silkscreened on onto the front right corner of the board. This motherboard has been used in systems made by Micron and other vendors. This BIOS upgrade is based on Phoenix 4.05 code and includes support for large hard drives (over 8.4GB) and for Plug-and-Play.

Check and record CMOS settings - especially hard drives and COM ports.
Since this motherboard uses a flash chip for its system BIOS, our upgrade is supplied on a diskette.
Boot clean from floppy in drive A: Error message "Protected mode memory manager detected" from INSTALL program indicates system was not booted clean (without EMM386). Make sure that Install diskette is write-protected. Insert Micro Firmware Installation diskette, type INSTALL, follow prompts. Install program will ask for blank, formatted, high-density floppy disk for drive A: to create a recovery disk.
When prompted, remove recovery disk, label it, and save it. This disk is a copy of the original BIOS. See section 4 for reinstallation instructions.
The Install program will reboot the system. It may be necessary to enter CMOS SETUP and adjust SETUP values.
NOTE - memory managers such as QEMM may need to be reinstalled from scratch after upgrade. See REMQEMM.TXT.
"Unable to access flash device" error message during installation usually indicates incorrect BIOS upgrade for motherboard or problem with flash chip.
If INSTALL program hangs on "Gathering System Information", one or more expansion cards may need to be temporarily removed.
The M5HS10 BIOS is compressed in the flash chip and decompressed as it copies into shadow RAM when the system is powered on. Although there may be BIOS code throughout the E000 and F000 segments, only the code in the top 2/3 of the F000 segment is used once the system is up and running. It may be useful to Include the area E000 to F3FF if using a memory manager such as EMM386. This would be the recommended parameter to add to the EMM386 line in CONFIG.SYS:
We do not recommend using the HIGHSCAN parameter with EMM386. After adding the above parameters to EMM386, MEMMAKER should be rerun. When running MEMMAKER, use the CUSTOM mode (not the EXPRESS mode) so that existing inclusions and exclusions will be preserved. If using QEMM or other aggressive memory managers it may also be useful to add the additional exclusion - X=F300-FE00. Also, if QEMM does not seem to be working out after BIOS upgrade, it may be necessary to remove it entirely (removing all references from AUTOEXEC.BAT and CONFIG.SYS) and then reinstall it from scratch. We have a document available to help with this procedure - REMQEMM.TXT. If using WIN95 - EMM386 is not needed. Since WIN95 uses a "flat" memory model, there is probably no need to recover any memory in the E000 range that may be getting excluded.
I=E000-F2FF
Error message "Invalid System Configuration - Run Configuration Utility"
This message is from the BIOS and indicates that the ESCD (the area in the flash chip used to store Plug and Play information) has invalid or corrupted data and must be reset. This is done by setting the option "Reset Configuration Data" (on the Advanced menu in CMOS setup) to YES. This option will automatically be set back to NO after rebooting.

Various improvements to PnP code.
After installing M5HS10, the original BIOS can be reinstalled in two different ways, described below. A valid recovery disk is required for either method. This disk is created during the process of installing M5HS10. We can provide a replacement disk if needed.
1. Boot from recovery disk.
Power system off, insert recovery disk, power system back on. The following message will display:
2. INSTALL UNINSTALL
Installing BIOS from Recovery Disk.
When this process is finished 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)
Boot clean from floppy in drive A: Insert Micro Firmware Installation diskette, type INSTALL UNINSTALL. When prompted, insert recovery diskette (created during installation). When finished, system will reboot.
Original CMOS SETUP values will be lost - SETUP must be reprogrammed.
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 availableo n our BBS, FTP site, or web site. The file M54HIRD.EXE contains a self-extracting diskette image of a recovery disk which will install M-M54Hi-10PM.
Boot Block Recovery Procedure:
1. Turn system off.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.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 15 to 25 seconds, the speaker will sound one
long and two short beeps. The display screen will remain blank.
The diskette drive light will come on, there will be another beep.
In about 30 seconds, there will be four beeps to indicate that the
process is finished.5. Remove recovery disk.
6. 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.
The BIOS code resides in the flash chip but the values selected in the SETUP program are stored in CMOS RAM, which on this motherboard is in the clock chip located in socket U17 in the back right corner of the motherboard.
This chip may be a Dallas 12887 or 12887A (in which case the battery is built-in to the clock chip) or it may be a Motorolla 146818 (MC146818AC) or compatible (KS82C6818A, HD146818AP or other number ending in 6818) in which case an external battery will be plugged in to the motherboard.
In some situations, such as when a password has been set and has been forgotten, it may be necessary to clear CMOS RAM.
This motherboard has a CMOS Clear jumper, W12, located just behind the flash chip, which is just behind the clock chip. It is normally open. Shorting these two pins with power off will clear CMOS RAM ONLY if a Dallas 12887A is present. CMOS RAM can not be cleared on the Dallas 12887. It is normally recommended to replace the Dallas 12887 with a 12887A due to this limitation. The 146818 chips cannot be cleared using the jumper.
If a Motorolla 146818 or compatible chip is used - CMOS RAM can be cleared in 3 ways: 1. Unplug the battery and the power supply and wait for anywhere
from 2 hours to 2 days. 2. Remove the chip from its socket for a few seconds (with power off)
and replace. (If guiding someone through this procedure over the
phone, make sure they do not try to pry up the socket instead of
the chip.) 3. Short pins 12 and 24 for a few seconds with power off.
It is greatly preferable to short the pins instead of removing the
chip due to the possiblity of damaging the chip by breaking off
pins. Use a paperclip bent into a U shape. Here is a picture of the
6818 chip:
___________
1 | * U | 24 ******

****** 12 |__________| 13ALSO: The same results can be obtained by using a simple DEBUG script to invalidate CMOS RAM. This will be much more convenient than shorting pins on the clock chip in cases where it is possible to boot to a DOS prompt to run DEBUG. Here is a DEBUG script to invalidate CMOS RAM. (This should work on all AT motherboards).
A:\>DEBUG
- o 70 2E
- o 71 FF
- QAfter clearing CMOS RAM we should get an error message on bootup such as CMOS Battery Dead, Clock Chip Lost Power, or maybe just CMOS Checksum Invalid, and default values should be loaded. The loading of default values after invalidating CMOS RAM is usually more thorough than the loading of default values by choosing the option to load default values in CMOS setup.
NOTE: the 6818 chips have 24 pins - 12 on each side
The Dallas chip has 19 pins - the unused pins are missing
Various BIOS versions have been supplied on this motherboard. Many of these are available on Micron's web site and on Micronics' web site. The ones we have seen are listed below.
From Micron's web site:4.04 MM54Hi-01PM 03/21/95 4.04 MM54Hi-01P 03/20/95 4.04 M-M54Hi-02PM 05/03/95 4.04 M-M54Hi-02P 05/11/95 4.04 M-M54Hi-07PM 08/15/95 4.04 M-M54Hi-08PM 08/29/95 4.04 M-M54Hi-09PM 09/14/95 4.04 M-M54Hi-10PM 01/02/96 4.04 M-M54Hi-11 07/30/98
NOTE: The ZIP file, HI_10.ZIP, contains two BIOS image files, M54HI_10.PM and M54HI_10.PS2 , which both display as MM54Hi-10PM and both have the same date. The BIOSes are identical. Different resources have been reserved in the ESCD to help with setting up legacy cards.
From Micronics' web site:
4.04 M54Hi-02P 05/03/95 4.04 M54Hi-05P 07/23/95 4.04 M54Hi-06P 12/19/95
All of these BIOSes support drives up to 3.2GB. Due to a bug in the drive size calculation routines, the cylinder field in CMOS setup will accept values only up to 6349 (3276MB). This assumes that the heads are 16 and the sectors 63. Cylinder values from 6350 to 8322 will cause lockup in CMOS setup. Values 8323 and higher are OK. Does not work with drives over 4.2GB if heads are 16 - can use workaround parameters. Although the value for drive capacity in CMOS setup will wrap around, the drive can be seen correctly by FDISK.
All of these BIOSes have the Year 2000 date rollover problem except revision 11, which appears to have been released just to fix the date rollover problem.
5/95 and older BIOSes use Intel PnP extensions. 7/95 and newer BIOSes use Phoenix PnP code.
NOTE - As described in section 7, there are at least 11 original BIOS versions for this motherboard. Setup options will vary among those versions. The most recent version is described here.

W2, W13 - Sets internal CPU multiplier. The internal multipliers on
Pentium Overdrive and MMX Pentium Overdrive CPUs are fixed at x2.5,
so W2 and W13 have no effect on the Overdrive CPUs. W13 is not
present on REV A boards, so they will not run 150 or 166 MHz
Pentiums at full speed.W4,W5,W30 - Work together to set the CPU bus speed.
The regular Pentium Overdrive CPUs have the same ID bytes as the regular Pentiums, so they are ID'ed the same by the BIOS.
* 133MHz and faster Pentiums (and the POD MMX 200) are intended to be
used only with a Socket 7. This motherboard has a Socket 5. Most
likely, this is not a problem on this board. Micronics does document
jumper settings for 133, 150, and 166MHz Pentiums.**In the first release of M5HS10 (4.05.09), 125MHz CPUs will ID as
120MHz. This is cosmetic only, the CPU is actually running at 125MHz.It may be necessary to pay attention to jumper W3, which selects between VR and VRE voltages. On Pentiums rated for standard voltage, the state of this jumper shouldn't matter. If a CPU is rated for VR or VRE voltage, W3 should be set accordingly. As a rule, VR applys to some 75, 90, and 133 MHz Pentiums, VRE applies to some 100, 120, and 166 MHz Pentiums, while Pentiums of all these speeds may also be rated for standard voltage. Here is some additional information on this excerpted from our text file PENTIUM.TXT: http://www.firmware.com/support/bios/pentium.htm
75-200MHx Pentiums are rated for different voltages. Some motherboards will have jumpers to set different voltages for Pentium CPUs. All Pentium CPUs are marked with an S-Spec number. This is a five-character value beginning with SK, SU, SX, SY or SZ. The S-Spec number will appear on top of the CPU and sometimes on the bottom. On some CPUs, the S-Spec number is followed by a slash and three letters. The first letter indicates the voltage. S = Standard voltage, V = VRE voltage. If there are no characters following the S-Spec number, the S-Spec number will need to be referenced to determine the voltage specification. There is a chart in the Pentium FAQ on Intel's web site that lists S-Spec numbers and gives corresponding characteristics. Here is the URL for the Pentium FAQ: http://www.intel.com/procs/support/faqs/ppfaqx2.htm There are 3 different voltage ratings for Pentium CPUs: Standard Voltage = 3.135v - 3.6v VR (reduced voltage) = 3.300v - 3.465v VRE (reduced voltage and shifted range)
B-step = 3.45v - 3.60v
C2-step and higher = 3.40v - 3.60v If a Pentium is rated for standard voltage, it shouldn't matter how a motherboard is jumpered. If a motherboard has CPU voltage jumpers, it may be necessary to determine the voltage rating on the CPU in order to determine how to set the voltage jumpers.Have had a report of Evergreen Spectra 333 (with AMD K6) working OK with M5HS10.
