How Do I Update My Bios?

I have two older motherboards I plan to update the BIOS on. I'm doing a 775 to 771 mod and have the BIOS' I need, ready to go. Both files contain an exe and a BIOS file. I imagine I need to get into a DOS environment to run the EXE file. My problem is the BIOS update instructions call for boot floppies created from Windows 98 to XP. I can't make those using Windows 10 and I'm trying to figure out what I should be using instead. Any ideas?

In case anybody is curious, these are the instructions included with the BIOS.

4. Boot your system from a Win98 or WinME boot-floppy.

How to make boot floppy in case your don’t have it ready:

For Win9X, You can type [C:\ format a:/s] from the DOS prompt.

For WinME, You can make a boot floppy from control panel--> add/remove program-->make boot floppy. Remove autoexec.bat & config.sys file if there's any.

For Win2000, there's no way to make boot floppy, so you have to either use Win9X or WinME boot floppy.

For WinXP, you can make a DOS boot disk. Go to Your Computer, right click drive A:, select Format, select copy system files.

5. When you get the A:\ prompt, type the following sequence:
C: <enter>
cd\test <enter>
C:\test> adsfi719 BIOS file

Firstly, why do you want to update the BIOS?

 

Looks like the original link wasn't pointing to the correct page. This is the correct link. I am performing a mod to my LGA 775 motherboards that lets me install faster Intel Xeon processors (LGA 771) into a Core 2 Quad motherboard (LGA 775). These 775 boards do not natively support 771 microcode. So the BIOS' have been modified with 771 microcode and now the BIOS of each board needs to be flashed so it will support a 771 CPU.

I am aware of the risks and have decided to go forward anyway. I have other PCs, so if this flops, it will be unfortunate, but not crisis inducing. I am prepared for failure. The only question left on my mind is what is the appropriate boot environment to run the BIOS flashing EXE within?

 

For anybody else who is curious, this approached was simple enough. I just configured Rufus for FreeDOS, added my BIOS flashing files, and I was good to go.

Let us know how the BIOS update went.

 

The BIOS updated successfully. FreeDOS was perfect and everything went according to plan. Now I just need to put the new hardware in to see if my BIOS actually contained the microcode necessary to support this XEON

 

You have verified your processor with your Windows version you'll be running?

No, I wouldn't have even though it could be an issue. I'm using Windows 10 Pro 20H2 and this will be a Xeon E5450. According to the page you linked Windows 10 only supports Xeon 52xx processors. At least that is what I believe I am reading. Does this mean the new PC won't even run with Windows 10 and this processor?

Look for an earlier version. After that it will probably not be offered an update past a certain point. I don't know how MS handles lessor hardware. Getting a proper Xeon might be cheaper and easier.

 

That ship has sailed. I already own it. I guess I will find out soon enough. Going to be installing it tomorrow *fingers crossed*

 

I believe I read some will work but won't be able to get certification by MS. Depends on what those 2 pins are used for. Keep us posted.

See this..... especially the last post.....
