Update BIOS from DOS command line?

[VideoDadUS]

Hello,

I'd like to be able to flash the BIOS from the boot prompt or with a USB/CD/DVD based tool. I cannot open any OS even from live DVDs.

My Presario SR5507F came originally with Vista installed but over the years it was upgraded to Windows 8.1. It gave us years of reliable service but sometime last fall the PC started experiencing seemingly random reboots and powerdowns.

Things got pregressively worse until the PC was unusable. It would run for 15 or 20 minutes and then reboot. The problems started shortly after a Windows update, so I thought this was a patch or driver update issue. I tried reverting an removing patches to no avail. I also tried installing Ubuntu and Fedora, but they exhibit the same issues. Fedora is worse than Ubuntu, though. I tried to reinstall Windows 8.1, then 7 and finally the original Vista 32-bit OS but all Windows installations fail at some point during drivers installation. The computer just enters an endless reboot cyle and Windows cannot be installed.

I ran memory tests but they all pass and I can use a text based OS, such as DOS.

I have tried to reflash the BIOS, thinking it may have been corrupted during one of the reboots, but since I cannot install any version of Windows, the BIOS flash tools refuse to work. I need to be able to flash the BIOS from the DOS command prompt or at boot. Is there such a tool from Compaq/HP?

Thanks!

There may be a way to reflash from DOS but the DRIVERS PAGE for the Compaq Presario SR5507F Desktop PC shows two different motherboards. 

MCP61PM-HM Motherboard

and

M2N68-LA Motherboard

Please verify which one this PC has, then I can help you in the procedure to flash from DOS.

That would be great news!

My PC's mother board is the MCP61PM-HM Rev 1.0B.

Thanks for your quick reply!

sp40911.exe

Open the download after it is complete with 7-zip by right clicking on the sp40911.exe, then extract the Net5.24 to a known location.  AWDFlash download

Just rename the file to 524.bin and use awdflash from DOS.

Use  awdflash 524.bin /cc/cd/cp/py/R

The version posted should work for that.  Just remember you have to boot to DOS, not a DOS windows inside of Windows.
