HP Compaq dc7900 Desktop PC series - Update the BIOS Without Accessing the Operating System Information The following technique will allow the BIOS to be updated before starting the OS.

Hi guys I'm having an issue with a HP Compaq dc7800 Convertible Minitower PC where it doesn't post or start an install of any windows Vista/7/8 apart from Windows XP. I've also tried to test it with Ubuntu but it crashes aswell. I've pin pointed the issue to be with the NVidia Quadro VS 440 card that's installed in the machine as once removed and using the onboard graphics then all works fine.

But I would like to keep the card as the plan would be to use 4 monitors, This is the BSOD that gets generated with the card in.

I've also gone in a search for the NVidia NVS 440 bios update but no luck with finding any.

Any help or tips? I've used Windows XP, Vista & Windows 7 on an array of different DC7800 SFF which I believe share the same motherboard as the mini-tower without issue.

Hi: Here is all the info you need to update the microcode for your dc7800's. Files are the same for the SFF's and CMT's. You have to copy the DOS flash files in the microcode update folder to a bootable usb flash drive, with DOS command files on it. Put the flash drive in the PC, turn it on and the PC should boot to the usb flash drive.

At the command prompt, type Flashbin.exe and hit the enter key. Follow the on screen instructions to update the microcode. I zipped up and attached the utility to make a bootable flash drive below, the DOS command files you need, as well as the dc7800 microcode update files.

You make the bootable flash drive first by running sp27608. After the utility has formatted the drive and made it bootable, copy the dos files to it, then copy the Microcode update files to it. Copy just the files in the folders, not the folders. After you update the microcodes, I will give you the instructions to update the BIOS.

I don't want to confuse the attached microcode files with the BIOS files. So, you can let me know when you have completed that process. Updating the BIOS will be easier. I have a dc7800 CMT, and used those same files and methods to update the microcode. I didn't even bother to format the flash drive.

I let sp27608 do that for me, and it made the flash drive bootable. Then I copied the file contents of those other 2 folders to the flash drive, and when I put it in the PC, tapped the F9 key at the beginning of the HP welcome screen, selected the flash drive from the bootable device menu, it booted just fine to a command prompt, and then I typed flashbin.exe hit the return key, and off went the microcode update. Did the above to flash a 7800p and I know where the directions falter. Use the files that Paul linked 1. Open the SP27608 zip and install it. Now when you run this select Create a DOS startup disk and check 'using DOS system files located at' 3. Next unzip the file titled DOS System Files you dl'ed from up top 4.
