Specs: Windows XP, pentium
i have a few of the dc7800`s. this same issue started when i upgraded to 1.32 bios version hp business bios version.

Today i was finally able to bring one of these computers back to life. I will try another one and document what steps i took. i will do my best to explain what i did.

First i tried to flash the bios back to a previous version. no luck
i downloaded the bios version 1.32 from hp and placed it on a flash drive. i reflashed the bios and went into the bios and turned on mxe or mbe prompt. (its enables the control P)
when computer booted i hit the control P and entered the setup. I turned of AMT. 3 OPTIONS available. off amt and something else. I had to enable something at the first screen to get to this screen. i saved and exited and the computer booted up ok.

sorry for the vague instructions. I will attempt this on another one of my dc7800s and try to post some clearer instructions.

What was the reason you updated BIOS? These are not done on a routine basis, only for some specific reason such as a change or processor. If they go wrong they can brick your motherboard.

"I had to enable something at the first screen"
Let us know exactly what you enabled please.

Always pop back and let us know the outcome - thanks

Here's what BIOS v1.32 does: "Improves security of the BIOS flashing process under certain circumstances by adding a stronger flash process verification algorithm."

Also, nothing is mentioned about using a USB flash drive to update the BIOS. Here are the instructions from the HP/Compaq site:

"Several methods for changing the BIOS version may be chosen. Included in this
package are the following methods:

- Use the DOS utility with a preboot execution environment (PXE) management
application to locally update or restore the system BIOS.
- Use HPQFlash to upgrade the BIOS directly in a Microsoft Windows or Microsoft
Windows Vista environment.
- Create a CD image to upgrade/restore system BIOS."
