M82 ThinkCentre - Type 3302. Model number: 3302F2U
This machine was originally purchased with the Windows 7 Pro operating system. I took advantage of the free Windows 10 upgrade when it was available over a year ago.
A few days ago I had to replace the motherboard. The computer is running fine. However, when it first boots there are 2 short beeps with an EEOC error. This error referenced the BIOS containing invalid Model Number and Serial Number. When I access the BIOS the following entries are seen:
1) Machine Type and Model INVALID
2) System Brand ID Lenovo Product
3) System Serial Number INVALID
4) Asset Tag
5) System UUID FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF
6) Ethernet MAC Address FC-4D-D4-DB-34-F7
7) BIOS Revision Level 9SKT75AUS
8) Boot Block Revision Level 9S75A
9) BIOS Date 09/17/2013
I see references to using WinPhlash to manually update the needed settings. However, I'm unsure (because of my upgraded from Windows 7 Pro to Windows 10 Pro) of which BIOS upgrade to use.
I'd like to get that info along with instructions of exactly "how to" complete this process.

At the start of the BIOS update process, it gives you option to enter or change those (use CD ISO update only.)

The Lenovo website has a section describing commands used to insert/edit the Model number and/or Serial number via the command line interface. As follows:
1) Insert Model #: flash2.exe /mtm:3302F2U
2) Insert Serial #: flash2.exe /sn:#######
I've burned the ISO image to a CD and inserted into the computer in question. Must I reboot in order to use the commands above or just go to a command prompt and enter the commands.?
I've just spent a lot of money for this new motherboard and don't want to make any mistakes.
Mod's Edit: Serial number removed from public view to protect owner from its unwanted use.

Boot from that CD, when the standalone installer loads (making it independent of the OS on the system, and any problems with it -- therefore the prefered update method), it will ask if you want to update the serial number, the model number after that. I reran the last update for my M73 system, here are the prompts:

Screenshots were perfect - those are the prompts I received.
After entering the Serial # and Machine Type, it looks as though the BIOS was getting upgraded. At least by the command line entries that were appearing onscreen.
I'm now at a prompt asking, "BIOS ROM file is older than (or same as) the current BIOS ROM image." Continue anyway? (Y,y) or (N,n)?
Which should I choose?

My fault for last post. It seems the BIOS did get updated during the steps used to enter new Serial # and Model #.
The machine rebooted and because I had left my bootable Cd in the drive, it prompted me again for BIOS update. I answered "No", rebooted again and all is well.
Thanks for your help!
