ASRock 939Dual-SATA2 Beta BIOS

post #1 of 5
Thread Starter 
I updated my bios to a beta version that was supplied by OCWorkBench. This bios is not a lot different. For the better part it just sets defaults that are ideal to overclocking that takes a lot of experimenting and guess work out of it.

One thing it does do is allow you to set your memory all the way down to a clock frequency of 100MHz that allows you to run your memory at a 2:1 divider. This just enables you to push your CPU, taking your memory out of the equation.

There are several official and beta bio versions for the ASRock 939Dual-SATA2. I am sure you are well aware of the different ASRock official bios versions, and the OCWorkBench beta bios are just slight variations of those official bios versions. You will want to use the OCWBeta1 or OCWBeta2 because the verions 3 through 5 have a 274 HTT lock. I personally used the OCWBeta2 because it had updates for Opteron support.

You will want to follow the ASRock instructions for flashing your bios:

BIOS Update Utility

ASRFLASH.EXE: The Flash Memory Writer utility is included in the WinZip format of BIOS file. It updates the BIOS by uploading a new BIOS file to the programmable flash ROM chip on the motherboard. To determine the BIOS version of your motherboard, press <F2> to enter the BIOS setup utility during bootup, and check the BIOS version from the Main menu. Larger numbers represent a newer BIOS file. This utility works only in DOS mode.

The Flash Memory Writer utility can not be suitable for all ASRock motherboards. Please use the Flash utility which is included in each BIOS file to update its BIOS. Also ASRock motherboard MUST use ASRock's Flash utility to update BIOS, those uncertified BIOS flashing tools will cause motherboard damage.

Updating BIOS Procedures

1. Create a bootable system floppy disk. (Insert Floppy Disk-->Start-->My Computer-->Right Click on Floppy Drive-->Select Format-->Select Create Boot Disk)
2. Download an updated ASRock BIOS file (WinZip format with .zip file extension) from the web site, unzip the BIOS file and save both ASRFLASH.EXE utility and BIOS file to the disk you created in step 1. (You are going to want to create this for whatever version of the official bios you want. You will also have to add the ASRflash.exe utility to your beta bios disk. So once you have both the ASRflash and ocwbeta2.rom on a bootable disk you will be ready to go)
3. Boot from the disk you created in step 2.
4. At the "A:\\" prompt, type ASRFLASH, hit space bar once, and type BIOS file name then press <Enter>. For example: A:\\ASRFLASH K7S41GX2.00 (A:\\ASRflash ocwbeta2.rom (Provided you will be using ocwbeta2, so fill in that part for whatever bios version you use.)) <Enter> then you will see a message "Please wait for BIOS loading ROM".
5. After 30 seconds, you will see the message "Flash ROM Update Completed - Pass", then you have finished upgrading the BIOS.
6. After finishing upgrading the BIOS, please remove the floppy disk. Restart your system and press <F2> to enter the BIOS setup utility during boot up.
7. In Exit menu, please select "Load Default Settings" and press <Enter> to continue.
8. Select "Exit Saving Changes" and press <Enter> to exit the BIOS setup utility.
9. Now, system is booting up with new BIOS.

Notice : If you encounter problems while updating the new BIOS, DO NOT turn off your system since this corrupt BIOS might cause your system failed to boot up. Just repeat the process, and if the problem still persists, update the original BIOS file. If the Flash Memory Writer utility was not able to successfully update a complete BIOS file, your system may not be able to boot up. If this happens, your system will need service.


For those of you with Athlon 3000+ or Opteron 144 with multipliers of 9x you will definitely gain an advantage with ocwbeta1 or ocwbeta2. If you are uncomfortable using an unapproved bios then I do not recommend using this. The official ASRock 939Dual-SATA2 1.20 does not have the 274 HTT lock either if you are more comfortable with this.

I was able to push my processor to 2920MHz using this bios version, where I was only able to get around 2700MHz with the ASRock 939Dual-SATA2 bios 1.50.

Not with this file. I don't think the OC Workbench bios or ASRock official bios are configured to be an ISO Image file. I guess you will have to invest the minimal amount of money in a floppy drive if you want to run a different ASRock bios.

The question proposed by SneakyMonkey got my interest peaked. I thought why can't you convert a floppy file to a iso image file and burn it to a cd-rom? Apparently it is possible, but it is not recommended. There is a great guide out there at http://www.bay-wolf.com/bootcd6.htm

The guide uses Nero Burning ROM version 6 and has a link to version 5.5. So if you are using a software such as Roxio you will have to see if you can mimic the steps in the guide. A Bios is nothing to mess around with, and I recommend that you invest the $10 dollars for the floppy drive. If you are uninclined or unable to get a floppy drive then you can give this a whirl.
