How do I get more than 1.7V on my BH6?

[Slayer]

heya guys
I have just picked up a celly 566 and a asus slocket and have it running on my Abit BH6 rev 1.2 mobo with the sp bios. I can get the celly somewhat stable at around 893 (105fsb this is using 1.7V which is the maximum i can choose in the bios. My question is how can I get 1.75V or more. My Asus slocket allows voltage changes via jumpers but when i change them it has no affect as the voltage remains as the bios has set it. How do i get above the 1.7V?
thanks for your help

I'd like to hear about that too...
I've heard somehting about reflashing the bios...or something.. i hope somebody who know the procedure posts soon..

I flashed to the QN bios before installing my Celeron 566 and I'm able to set 1.75 no problem. I guess now there is a newer bios (SS) that supports Celerons >600 MHz.

I have a revision 1.0 BH6.

I'm running at 100 MHz (850 MHz) without a problem.

The newest bios revisions recognize the 566 correctly.

You should be able to adjust in bios up from 1.50V in 0.5V increments up to >2.0V (original Celeron was 2.0V).

Good luck.

The time-honored method of upping the available voltage on an Abit board equipped w/ SoftMenu is to set the voltage to the highest (reasonable) voltage you can, then flash the BIOS, using the /cc switch. When you get up and running after the flash you should have more available voltages.

THE ABIT BIOS TRICK; for Abit BX6 and BH6 era motherboards.
Before you do anything else, Enter your Bios (enter ?Del? key while the computer posts) and write down your existing Bios settings or use ?print screen? to print them out. Sometimes you have to exit and re-enter the Bios several times to ?Print screen? each page.
1: First of all, download the desired Bios ?*.bin? file and flash program ? ?awdflash.exe?.
2: Execute the downloaded ?*.exe? Bios file to expand it for use.
3: Format a diskette with the copy system files command or go to the Dos prompt and enter: format a:/s (Don?t take a chance on an old floppy that you formatted 5 years ago!)
4: Copy the ?*.bin? file you got after executing the ?*.exe? Bios file to the floppy.
Write down the name of the .bin file: example -- Bh6_kg.bin
5: Copy the ?awdflash.exe? program to the floppy.
6: Reboot the computer.
7: Now enter your Bios again.

Step 1: Set your CPU Bios settings to default. (Don?t run overclocked or out of spec.)
Step 2: Set voltage to ?user defined? and then set your voltage to the maximum you have available; usually 2.3 volts for CPUs with 2.0 volt defaults. (older celerons) or 1.7 volts for Celeron IIs for example.
Step 3: In the Bios Features Setup; set the boot sequence to: ?a,c,scsi?. if necessary,
and enable " Boot Up Floppy Seek" if necessary, to boot to your floppy.
Step 4: Save settings and restart.

Now the computer will start from the floppy.
When you are at the ?A: prompt? in Dos, you are ready to flash the Bios.

1: Type ?awdflash? and the flash program starts.
2: Type in the name of the .bin file (i.e. BH6_kg.bin) - or the one you wrote down previously; and press ?Enter?. The Bios flash screen comes up and provides you a blank to enter the ?*.bin ? file.
3: The flash program will ask you if you want to save the old Bios - answer ?yes?!
4: Save the old Bios to the floppy with any name you like - I use "old.bin" - and then press ?enter?.
5: After the flash program has saved the old Bios it will ask you if you want to program the Bios - answer ?NO?.
6: The flash program will now terminate and return to your floppy drive.
What you have done now is to save your old Bios - and you now have the opportunity to flash back to the previously Bios again. When you do the Bios trick as a single command line with all the switches, you don?t have the opportunity to save the Bios at that time.
Now you are ready to trick your Bios voltage settings!
7: The trick is NOT to start the flash program as you did previously: let?s say you have downloaded the ?kg? Bios and now you have a file called Bh6_kg.bin on your floppy - Right ?
8: Type exactly as follows for the BH6 ?kg? Bios: awdflash.exe bh6_kg.bin /py /sn /cc
9: Another example ? for the BH6 ?jj? Bios: awdflash.exe bh6_jj.bin /py /sn /cc
Now press ?enter? to begin. It takes about 30 seconds. Later press F10 to exit program when all activity on the screen stops.
10: Restart and go into your Bios settings - now you will see that the higher voltage is now the default. If the ?new default? is 1.7 volts, you will now be able to reach 1.9 volts!!! Don?t forget to reset your Bios settings before booting into Windows or you might find Windows installing ?Com ports?, etc. that you don?t want installed.

correct amundo.

I was gonna post the procedure, but others beat me to it
Anyway, make sure you get the latest SS BIOS. It worked a lot better than the QN for me(that's only my own personal experience).

 

[JasonG]

What problems did you have with QN?

Thanks,

Jason

Specifically, the screen colors were all weird and flashing when I entered BIOS. When I press a button, the flashing would stop at whatever color it was at, and the color isn't the standard blue/yellow/red scheme.

Also, SS just seems more stable. With QN, my C566 couldn't run at 850MHz stably at all at 1.7V, it would lockup immediately after reaching Windows. With SS, it still won't run stably at 1.7V, but it only locks up after a few minutes. I'm not runninmy C566it at 875.5MHz stably at 1.85V with SS. Of course, take what I say with a grain of salt since its only my personal experience, but then again, since SS is the newest version, there's no reason why you should choose QN over it.

QN messed w/ my com port settings, and I had to reinstall my internal ISA modem. I moved up to SS and the com port issues went away.

wowee you have got to love this messsage board. I post a message just before going to bed in Australia and come back to be greeted with the answers. thanks alot for your help guys esp Nick Stone. I'll go give that method a go now once again thanks

 

[JasonG]

Thanks for the info guys.

They must have come out with SS right after I flashed with QN. That figures!

Everything is running fine at this point so not sure I want to screw around with it.

I'm installing a new hard drive soon (IBM GXP75 30 GB with a promise ata100 controller) so maybe I'll flash to the new bios before that.

Thanks again.

Jason

Jason, when it comes to BIOS, if it works, don't mess with it.
