Serial Number

[efray]

The problem from the start is that in error messages appear to update the BIOS and firmware and after updating the BIOS this error occurred and change the input UUID FFFFFFFF-FFFF-FFFF-FFFFFFFFFFFF 

I'm all in need if I go back to the original number until the device returns to the Internet

These images show the error in changing ID uuid

Does the back-panel of your computer look like the following?

Is there a similar white-coloured label on it?

Does the text on the label show the UUID?

There are no white stickers behind or from a special front uuid

My ID DA8E56C7-D2A7-11DE-BBDA-DE5F131C1CC1

What I need is no way to rewrite

In the field uuid

Are you saying that you want to prevent the changing of the UUID of a computer that is "in the field" ?

If so, then define a BIOS SETUP password, to prevent any person from changing the value in that field.

My friend problem from the beginning was in error messages to appear in the start of the device to update the BIOS and firmware and after updating the BIOS disappeared the global unique identifier and turned to

FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF

And also your Internet integrated mac TO FFFFFFFFFFFF

What I need is a tool to fix these IDs

That is weird.  Can you enter BIOS SETUP, and "disable" the integrated network adapter, and then add-in a PCI network adapter (with a "reasonable" MAC-address) ?

The picture does not show, until a moderator views the picture, and "approves" it, to allow it to be displayed.  This may take a few hours (today is "Good Friday", when many moderators are taking a day off).
