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:

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.
