Z210 SFF (XM857AV) BIOS boot problem

[GKre]

since some days my workstation is waiting a very long and unusual time in the black BIOS boot screen.

If i still wait the system is booting and working fine. But i wonder if there's any problem with the bios ore something else.

To troubleshoot i wanted to update the BIOS but all i could find was HP Workstations ME Firmware Update and Utilities. This did something out of a cmd-windows but i don't think that the BIOS was updated.

It is still Hewlett-Packard J51 v01.09, 17.05.2011
Heres some mory System Info:

Is there any help with this problem regarding

- the long wait time in BIOS screen

- maybe a link to latest BIOS

Thx in advance.

well - unfortunately i did not get any help or hint in this forum. But doing my own investigations i found out , that there's something in common with "bitlocker / TPM / Config Password".
I removed the Bitlocker Encryption from my HDD, disabled the config password and the TPM.
The machine did some strange things directly after that by booting / rebooting ....

But at the end the system is like it was before.

So i guess the problem could be in the context of the tpm.

Maybe this can help someone else in the same situation.
