Boot Warning Requiring me to press spacebar: Product information not valid. N/A Feature Byte etc.

[mlw19mlw91]

I bought this PC used.  The MOBO may have been replaced but it is still be an HP Motherboard.  I cannot get the relevant info from anywhere!  The bios warning is:

Product information not valid.  The following product infonrmation programmed into the system board is missing or invalid.

System Board (00A) - Feature Byte
System Board (00A) - Build ID
System Board (00A) - Serial Number

Press space bar to continue boot or 'Y' to enter missing information.

The stickers all over the board have numbers on them but none of them match what I need.  The relevant stickers may have been removed.  The information I do have from stickers and running the HP Bios tool is:

From Stickers:

PJDFA0ECYDJ1L3 (most likely serial but does not show up in HP part surfer or anywhere)
SP# L13216-001
SP# L13216-601 WIN
AS# L04857-003
REV 0E
L22948-003
CT: LJDHP0A8YDK08V

Now, from the HP Bios tool I get:

Product Number :  2YW27AV
UUID: 59E9FA39-4EA8-C4E6-46F8-BA4277937B46
System Board CT Number: PJDFA0ECYDJ1L3
System Board ID: 8455
SKU Number: 2YW27AV
Product Family: 103C_53335X HP Workstation
Exact Model: HP Z2 Tower G4 Workstation
BIOS Version: Q50 Ver. 01.08.11
Description :   HP Z2 Tower G4 Base Model Workstation

 There are no other visible stickers anywhere on the PC.

Help!

Ok guys it was a very scary problem to solve, since according to searches setting the wrong feature byte could break the system.

But, I just went on ebay and found a seller with the identical PC and a BIOS menu picture saying the feature byte.
I got all of his info and put it into my bios.  Before doing so, I confirmed the boards matched.

The error messages are now gone!
