I made a boot 'disk' with the Thinkpad Hardware Maintenance Diskette version 1.74. There are a whole bunch of utilities on it with the latest date being 3/30/2005. I'm guessing the SERUPDT.EXE (and not the older SERUPDT2.EXE) is the one to update the serial number. ATUUIDAL.EXE, UUIDCALL.EXE, AUTOUUID.EXE must deal with UUID. I needed to replace the Motherboard of a Lenovo Edge E531 laptop. We ordered a new motherboard (not from Lenovo) and i have it placed in the laptop.

Hi there. I got a problem with my Thinkpad.
It gives me these annoying (beeping) error messages for missing Serial Numbers (UUID) on the motherboard and I cannot figure out how to get rid of them.
It does not affect the performance of the system but is still a pain in the booty.
I figured out that one can insert a new serial number by using the Lenovo Hardware Maintenance Disk but the problem is that I do not have a Floppy Drive.
Is there a way to create a USB drive to boot with the HMD? So far I was able to get a HMD file version 1.72.
Unfortunately, I cannot find the solution in this link.

Any help is appreciated.
