MemTest USB was not detected on old desktop

[PeterK2]

Hi

I was working today with desktop from 2009 and it was not able to detect MemTest USB, even if there was option Boot from USB. Later I updated BIOS and USB was detected. Only thing I think it was problem that USB was FAT16. With the old BIOS for example NTFS USB with Windows was detected. Can be MemTest USB created as FAT32?

thanks

Technically it would be possible to use any files system. But we picked FAT as during testing it proved to be the most compatible with old and new systems.
