How do I flash my BIOS?

Specs: Windows 7

how do i go about flashing my BIOS? I've bought a new processor, and it cannot load b/c i need to flash my bios and replace them with a newer set. I have an HP a4302f. The processor I am attempting to install is a AMD Phenom II 955 Black edition quad core. It is compatible, my problem is that I cannot find the proper boot files. The ones provided on HP's site are in the form of "exe" and that cannot be used in any form to boot and upgrade my bios that i know of.

This is what HP shows with your number and Windows 7 64bit (readjust as needed). Please note that there are now programs that can flash a BIOS from within Windows on motherboards that support it. You will need to do this while the old working processor is in. After you shut down, you will need to clear CMOS (unplugged) when you change out the CPU before starting up again. Your online manual may give you more details.

You have to be a little bit crazy to keep you from going insane.

Black Edition CPUs are a "gift" from AMD to enthusiasts. The multiplier is fully unlocked allowing for numerous different clock setting options for maximum overclockability. HP systems are not overclockable so the potential of your CPU is going to go to waste.

I can't seem to find a program that would work this with my motherboard. Not to mention, the update for my BIOS on the HP site is "exe", so there are no boot files (and all of the programs to flash BIOS seem to require other forms of files, when all I am given is a "exe" update file from HP). HP told me to send it in, but they'd simply flash it to factory default, which is redundant because I need the more recent set of BIOS flashed.
What I'd need is a program to flash my BIOS and replace them with and "exe" update for the BIOS provided from HP.

You flash the BIOS version 5.61 from within Windows Vista or 7, what is so difficult ?

As above said it will be recognised as a standard CPU as the BIOS on these boards are locked to stop tweaking.

What is difficult is I do not know a program capable of doing so or what to use to safely Flash the 5.16 BIOS from within Windows. I have no disks or anything that came with my computer (as only a recovery disk for Win 7 was there), and there is no Flash BIOS programs available on either HPs sight, or the motherboard site.

The link in my last post IS the BIOS Execution file just run it and it will falsh the BIOS, providing you are running Vista or 7. If you do not have an O/S installed you can not flash the BIOS simple !

The link you provided is a link to the Update for my BIOS. It is not a flash program. It simply updates the BIOS and that will not do the job. I need the BIOS flashed, not updated. I need to use that Update but find a way to Flash it to my BIOS, as opposed to using it's "run" to update.

It is the same thing a BIOS Update does Flash the BIOS....

Maybe stop argueing and run that .EXE file in Windows 7....

I did run it. 3 times. There's no change. The processor will not load unless the new BIOS are flashed. I've spoken to HP on this and they've told me the same thing - it needs to be Flashed to the BIOS. Flashing the BIOS is completely erasing the older ones and replacing them. That is simply an update. It is not the same. To Flash the BIOS, a special program is needed for the motherboard, or you need to boot load the BIOS files to the computer in DOS.
I spent over 15 hours yesterday trying to find a program to do so, and couldn't find one.

There is a difference between updating and upgrading. To upgrade, is to flash them. Updating is simply an attempt to over-write. The BIOS are still giving the same commands as the original, b/c they're still there. Thus you cannot use newer compatible hardware.

I give up, I have used this method many many times on OEM PC/Laptops, but always prior to changing the CPU..

Craigyyuna, you're preaching to the choir. We know what flashing a BIOS is, how it's done & what it does. You have an HP system, not a custom system based on a "normal" motherboard, therefore you have to use the HP BIOS & perform the update the way HP describes. That means running the .EXE file from within Windows. If you attempt to do it any other way or with any other BIOS file, you risk trashing the board. Considering what it is, that may not be such a bad thing - lol.

Just so we're all on the same page, this is what you should be doing:

- you MUST have the old CPU installed
- boot into Windows
- download sp46428.exe from the HP site
- double click on it & follow the instructions
- after the BIOS update is completed, reboot & make sure you can still access Windows
- assuming all is well, shutdown & install your new CPU
- if it still doesn't work, buy a non-Black Edition CPU for your HP system or scrap the HP motherboard altogether & install a decent board based on a decent chipset. For example:

I understand what you're saying, and that was the first thing I did - update my BIOS. But before and after, I got the same message when inserting the CPU, "CPU unsupported, now shutting down." Upon further research and talking to HP's service people, they told me to send it in to get the BIOS flashed. Unfortunately, they'd simply flash it back to factory defaults.
I really honestly wish this was as easy as an update, but it's not it seems. Despite HP saying it's a compatible processor, I have to go through hell to make it work.
I posted here hoping someone knew an easier method of Flashing the BIOS, so I wouldn't have to take it to a computer store.

A "computer store" isn't going to be able to help you. Like I said, you have an HP board & MUST use the HP BIOS. If you want to use the Black Edition CPU, buy a decent board. That CPU is totally wasted on the sh!tty HP system anyway. If you insist on keeping the HP board, buy a different CPU.

Then which CPUs "would" be compatible?

On the same note, is it the "Black Edition" that is causing this processor it be incompatible?

It would be much cheaper to replace the motherboard with one based on one of the AMD 800 series chipsets, then overclock the heck out of the Black Edition CPU. Afterall, that's what the "Black Edition" is all about.

All I can tell you about upgrading the CPU is what's posted at the HP website:

"Processor upgrade information

•This motherboard supports only AM3 processors
•Memory support is limited to DDR3 modules only.
•HyperTransport 3.0
•Split power planes allow separate power management for CPU and integrated memory controller for improved power savings.
•Supports the following processors:
◦AMD Phenom II X4 9xx/9xxe/8xx Quad-Core (Deneb)
◦AMD Phenom II X3 7xx/7xxe Triple-Core (Heka)
◦AMD Phenom II X2 5xx (Callisto)
◦AMD Athlon II X4 6xx/6xxe (Propus)
◦AMD Athlon II X3 4xx/4xxe (Rana)
◦AMD Athlon II X2 2xx/2xxe (Regor)"

BTW, when you called HP tech support, did you make it clear to them that you have the Black Edition? Also, did you update the power supply in your system? Your new CPU is rated at 125W, the stock HP power supply is only 250W. The Athlon II x2 240e is an energy efficient CPU that only requires 45W, that's why they installed such a low wattage PSU.

I have already replaced the power supply to a 680W, I have also added in a different graphic card falling under the specifications.

The CPU I purchased falls under the listings given on the site.
AMD Phenom II 955 Black Edition Deneb falls under (◦AMD Phenom II X4 9xx/9xxe/8xx Quad-Core (Deneb)) And thus supported.

I have a proper power supply for the load, and that would not make the CPU incompatible with the motherboard. It would simply burn out the Power Supply if the wattage was too great.

I need to know what processors I may use. Would 95w be a limit? Is it the Black Edition that's making it incompatible? Etc etc.

Replacing the motherboard Is tough since I'd need to find a very similar board to what I have for the tower configuration. Switching the Graphic card, etc.

Ok, perhaps I am missing something or something isn't being said...
my CPU is under the specifications and part of the list of compatible CPUs for this motherboard. Forgive me if I don't know what Black edition does that makes a CPU incompatible, but if there is something, please do tell.
I do not wish to install a new motherboard, if I can simply upgrade my processor to one fitting the parameters

•Supports the following processors:
◦AMD Phenom II X4 9xx/9xxe/8xx Quad-Core (Deneb)
◦AMD Phenom II X3 7xx/7xxe Triple-Core (Heka)
◦AMD Phenom II X2 5xx (Callisto)
◦AMD Athlon II X4 6xx/6xxe (Propus)
◦AMD Athlon II X3 4xx/4xxe (Rana)
◦AMD Athlon II X2 2xx/2xxe (Regor)

The processor I purchased does fall under this unless the "Black Edition" somehow makes things incompatible (if so I didn't know) nor was it mentioned.

Would something like a
Phenom II X4 925 AM3 45NM 95-Watt 2800 Mhz
be compatible as opposed to the one I have.

The Black Edition is for computer enthusiasts who want to be able to increase their CPU speed to the optimal level that that particular ONE can be pushed and are willing to experiment to find the optimal settings to get there. Saying that the Black edition is a 'Gift' in because the multiplier is 'unlocked' which is another way of saying that the factory did not limit the number you can enter (at least not the same way a stock CPU is limited) so you can easily experiment with higher speeds until you find the best for you and for your particular CPU. This need to be able to adjust the multiplier against the HP BIOS' need to only use the preset locked number on a normal CPU makes it not compatible. Changing a motherboard is not as difficult as you are making it out to be, as is finding ATX, mATX, sizes to fit. The benefits of changing your MB to a much better one for not too much money vs getting an inferior CPU to fit your board should be a 'no-brainer'.

You have to be a little bit crazy to keep you from going insane.

Thanks. I really do appreciate the input. I may have sounded a bit naive, however I am simply trying to find a simple solution. I've learned a significant amount from these responses to assist in the next purchase. I will likely purchase another motherboard (despite how much I was dreading installing it into my tower it's clearly a better option).
I have a friend with one of the processors listed in the link provided by X86 above that I'll use in the mean time.
Once again, thanks for the help =)

You can't use a Phenom II X4 955 Black Edition on that motherboard, because the motherboard only supports up to 95w cpu's and the Phenom II X4 955 Black Edition is 125w cpu. That's the problem and it took me oh but 2 seconds to figure out just by looking at that link. Just because it says Phenom II X4 9 series doesn't mean it will support all Phenom II X4 9 series, because A) the BIOS has to be micoded to read that type of cpu and B) the motherboard watts has to support that cpu. And the latest BIOS frimware only fixes hanging issue there is nothing that states it will support a Phenom X4 II 955, because it simply can't the watts on the Phenom II X4 955 are too high for that motherboard to support.
