Is there a way to update the bios's from windows so I can do use SCCM to update all the bios's to the latest version. (dos util dosen't seem to run under x64 dos window)
Any way to reliably get into Ctrl P to enable mbex as it only seems to work about 1 in 100 trys. Seems very poor design.
Unfortunately, you have not provided any information about the models you wish to update.
Even if there are 300 devices, it will probably be a manageable number of models.
So I can't tell you if a BIOS update is available for all models as a .msi file.
Currently I have two models of the NUC in use, for both a .msi file is available.
I recommend to take a look at the downloadcenter.
Unfortunately I can't give you an answer for reading the serial numbers.
But maybe another member of the forum can give you a tip.
