Re: ms-7957 ver 1.0 HP ProDesk 490 G3 bios
From the original BIOS I extracted the WindowsKey. But I couldn't find in the forum how to write it in the new BIOS.

Hi hoaca388!
I tried your BIOS and it works.
Only at startup I get a message:
"Product Information not valid. The following product information programmed into system boards is missing or invalid.
System Board (00A) - System Board CT Number
Press space bar to continue boot or 'Y' to enter missing information."
I have nowhere to get this CT Number.
What would you advise me to do?...Leave a comment:

This is the original BIOS.
But with it the computer stopped working (black screen)
So I had to program it.
Excuse me!

Re: ms-7957 ver 1.0 HP ProDesk 490 G3 bios
I can't find this tool. I see it is for specific laptops.
My system is as follows:
HP ProDesk 490 G3 MT Business PC
SN: CZC61498SM
Prod.N: P5K11EA#AKS
motherboard ms-7957 ver 1.0
I used a file
MX25L12805D@HP ProDesk 400 G3_ME_Cleared.rar
by "abdnassar" #3
The inscriptions
"WARNING Machine is not in committed state.
System is booting in manufacturing program mode 28"
I can't remove them.
Please help!Leave a comment:

Re: ms-7957 ver 1.0 HP ProDesk 490 G3
I programmed the BIOS with this file.
At startup I have inscriptions:
"WARNING Machine is not in committed state.
System is booting in manufacturing program mode 28"
Then it loads normally.
How can I fix this?...Leave a comment:
