Hi:

You need to install the microcode update by using a bootable flash drive with the common MS DOS Command files and the contents of the microcode flash file included on the bootable flash drive.

Then you type Flashbin.exe at the command prompt you get when you boot from the flash drive, and hit the enter key.

Follow the on screen instructions to update the microcode.

I have attached the tool to make a usb flash drive bootable and the MS DOS system files to copy onto the flash drive.

See the 3 files below under Attachments.

Unzip and copy the DOS  files without any folders to the flash drive after you run the HP tool to make it bootable.

I have also zipped up and attached the microcode update files.

Unzip them and put them on the flash drive too without any folders after you make the drive bootable.

Dear Paul,

I've tried to do so, but I can't seem to make it work. 

I downloaded all files and unzipped them all. 

Using the SP27608 file I created a bootable usb flash drive.

Then I copied the files (just the files after unzipping, no folders) to the usb drive.

However I'm not able to boot from the usb, the computer asks me to please restart the pc using ctrl +alt+del.

Can you help me?

I do have Dc7600 small form factor and I'm running windows 7 at the moment. 

Thanks in advance

Hi, Daan:

If the HP USB formatting tool worked, you should be able to boot from the USB Flash drive by doing the following...

Insert the flash drive in a USB port.

Restart the PC.

Tap the F9 key at the beginning of the HP welcome screen to get the boot options menu.

Select the USB flash drive from the list of bootable devices and hit the enter key.

If that doesn't work try the procedures with a different USB flash drive.

If nothing works, unfortunately, I won't be able to help you with the problem you are having.

I know the process works because I have done it for many HP dc5800, dc7xxx and Elite 8xxx models, and given this procedure to other forum members.
