DC7800 SFF

Hello. After the processor replacement, cmos reset BIOS settings, now when booting you receive the error 2223-EIT Failure. VT must be enabled to launch VA. Enter F10 Setup and enable Intel Virtualization Technology. After you enable VTx and VTd, you receive the error 2224-EIT Failure Embedded Security must be available to launch VA. To help configure the BIOS so that the computer began to work. The menu is missing  "Embedded Security"

I read a lot of instructions, but nothing fits.
The error appeared after the processor replacement.
when the old processor was returned - the error remained.
"Embedded Security Device" in "Security -> Device security" is missing.

dc7800 now is not booting with HDD and USB. only CDD.
Please help in solving the problem.

BIOS v1.35

HP Recommended

I have one more motherboard vs7800 sff. May be I unsolder the BIOS chip, count the firmware of the programmer and flash the BIOS chip on MB that dont works?

HP Recommended

TPM should have been disabled before changing cpu, if possible reinstall original cpu and then disable TPM

install new cpu and renable TPM


note: most users do not require TPM functions, and as such should leave it disabled



the dc7800 has TPM hardware 1.2 on the motherboard     (latest win 10 requires TPM 2.0, for bitlocker to function)

this computer can not be upgraded to tpm 2.0, so bitlocker will not be available


to control/configure TPM, you must install HP protect Tools package v5.6





HP Recommended

unfortunately, I do not find in the BIOS menu TPM



reinstall original cpu - e2160 (processor was replaced by e6400)


 section "system security"  contains:

1. Data Execution Prevention (some models) (enable/disable) Helps prevent operating system security breaches.
2. Virtualization Technology (some models) (enable/disable) Controls the virtualization features of the processor. Changing this setting requires turning the computer off and then back on.
3. Virtualization Technology Directed I/O (some models) (enable/disable) Controls virtualization DMA
remapping features of the chipset. Changing this setting requires turning the computer off and then
back on.
BUT section "system security"  NO contains:
Trusted Execution Technology (some models) (enable/disable) 
HP Recommended

last time,  TPM on this model (dc7800) is not controled from the bios


you must install HP protect tools v5.6 in order to access TPM configuration settings


Last, some contries do not allow systems with TPM to be sold/used  (russia is one such country) as such there will not be a tpm module on the motherboard if you have one of thes systems then tpm is never going to work as it does not exist

we "walk in a circle"
that's what I wrote at the very beginning:

 my dts7800 sff can not boot.

Booting stops with error 2224.

Therefore, I can not install and apply the HP protect tools v5.6


maybe I understand you incorrectly?

but how then can I install a the HP protect tools?



HP Recommended

reinstall the e2160, then remove power from system (disconnect power plug)


now do a cmos reset, locate the small cmos battery on the motherboard and remove it


wait 20min,  power up system,   Press "F10" during the boot process before the operating system logo appears on-screen.


Enter the administrative password (if enabled)  Press "F9" to reset the password and restore the BIOS to its default configuration now power the system off and back on


now power off and reinstall cmos battery and boot again




do you still get any errors on bootup?


again what country are you from?

HP Recommended

I do not know how, but it worked out!


strange, but f9 did not have a response. I chose the default settings and turned off the computer with the power button.
after that, 7800 has booted! Hooray!

Thank you very much for your help!


I'm from Russia

HP Recommended

thought so, ...russian federation is a country that does not allow computers with TPM 2.0 to be sold or used.


as such HP systems sold legally in russa lack the TPM chip



Encryption products (not just TPM) implementing encryption with a certain strength level or higher, are subject to review and approval by Russian authorities. but i think you allready know this


HP Recommended

changed the processor and again the error returned.

now error:



But! now I can not reset it in the way that worked before.

now processor e2160 , VT -- enable/disable -- not result  ((


"VA Configuration" option in the MEBx -- not present ((



what am I to do now?


may try to remove protection using vista/win7 live-cd?

what programs should be on a live-cd?
