TO hercules:
I think that is what Peter is saying above.
So when I have time I will do it and keep my fingers crossed, I guess. I went to the pc chips website and downloaded what it says is the appropriate bios, it says to ignore the numbers on the end, just go by the first numbers when looking for the bios.
What I mean is, by mobo is the 728LMR and on the website is 728 by itself of 728 maybe with an L and with the MR. The website says to ignore that so I downloaded the 728 bios.
Between tonite and tomorrow night I will give it a try the way you and peter are suggesting, which I believe to be the same.
Also, on the pc chips website you will find the "manual" if you look hard enough. But like I said, it isnt much good unless I read it wrong. Matter of fact, here is a copy of what I got from there. I copied it to a text file:
NOTE: Flashing a Bios is risky and might leave you with a dead system.
DO NOT flash, if your system is working without problems.
I can't be responsible for the accuracy of this information, nor can I promise that you'll be able to solve all of your problems.
Further, you must consider and understand you do any modifications at your own risk.

The usual procedure
This is a step by setp guide.
Keep in mind, that your mileage may vary!
Identify your board model. Sometimes you even need to know the PCB-Layer Revision or some other technical data. If you are unsure: STOP!.
Get the Bios-Image for your board. Make sure, it is downloaded correct.
Create a bootable system disk, using Dos 6.2x, Win 9x or Caldera Dos.
Remove all files except io.sys, msdos.sys and command.com.
Keep in mind, that there are hidden files like drvspace.bin
Put a suitable flash programm on it.
Which one to choose? Check disks/cds that came with your board.
Nothing there, check if the manufacturer recommends a special version.
A flasher version from the time, the board was availabe is usually the best choice.
Check here for a particular AMI or AWARD flasher version.
Put the new Bios image on it. Check that windows hasn't screwed up the filename.
It should be a true Dos 8+3 name. Also check the file-attributes and remove any write protection.
Reboot and Enter the Bios Setup.
Set boot order to A: first and disable the "Internal" and "External" caches and "USB".
Best: Note all the current settings.
Save and Exit.
The PC should now boot from that floppy.
Start the flashprg with the parameter "/?" (without the quotes) and check the options.
Nearly all flasher version will give you the opportunity to save the current Bios to file.
This is, what you should do now.
Now start the flasher and flash the new Bios, using either a menu or command-line switches.
After a succesful flash, re-enter the Bios-setup and check all values.
Sometimes it is necessary to clear the cmos to bring the board with the new Bios back to life.
--------------------------------------------------------------------------------
Emergency procdure with AMI-Bios
Put a known working bios-image on a freshly formatted disk.
Name the file "AMIBOOT.ROM"
Insert the floppy and power up.
You may need to press "Ctrl"+"Home" to activate the emergency flash routine.
--------------------------------------------------------------------------------
Emergency procdure with AWARD-Bios
Put an autoexec.bat on that boot-disk you made.
it should contain one single line, which starts the flasher with all required parameters.
The parameters do vary from version to version, but you should have checked them already.
Insert the floppy and power up.
You may need install an ISA FDC, sinces sometimes the onboard FDC will not work.
Usually you won't see anything, unless you install an ISA VGA-Card.
--------------------------------------------------------------------------------
Other ways out
Hot-swap. Read the FAQ at Wim's Bios Page.
Flash services, like Flashbios (NL), Badflash (US) or Segor (DE).
A local electronics or pc shop may also be able to help you.
Buy a new flash-chip from the motherboard manufacturer.
--------------------------------------------------------------------------------
Getting a replacement chip
For 486 and early 586 boards (FX,VX and Opti-based) a small list does exist.
Which chip type to use, depends on the Letter appended to the Release Date of the Bios.
No Letter
Any type, because this is designed for a (E)PROM.
I
Intel 28F001BX flash chip only.
S
SST 29EE010 (5V)
Winbond 29EE011 (5V)
ATMEL 29C010 (5V)
intel 28F001BX (12V)
MX28F1000PPC (12 V)
L
MX28F1000PL (12 V)
MX28F1000PC (12 V)
DO NOT USE THIS LIST FOR BOARDS WHICH ALREADY HAVE A FLASH CHIP!
If you need to replace a chip on a board which already has a flashable chip, just buy exact the same model (Access time could be faster, no problem with that).
If you can't get hold of such a chip, you may wish to read the Bios-revision history for that very particular Bios you are going to install.
Sometimes you find additional chip-types mentioned there, which will be supported from a particular release version onward.
Example from such a file:
File name :e2k1201s.rom
check sum :2D89h
Release date :2000/12/01
ECN :SNG-2K0207
1. Support MAXTOR 36GB HDD.
2. Support Silentboot function.
3. Added BIOSLOCK function.
4. Support SST 49LF004 FWH flash parts.
5. Support Cyrix ¢» CPU.
6. Updated Microcode (686).
7. Added 66MHz CPU table 66*12 maximum.
Got it?
Just in case your board came equipped with an 2MBit-ASD chip, Winbond 29C020 chips will work as replacement. ASD seems to be some sort of OEM (or licensed from Winbond).
