My ASUS EZ Flash 3 BIOS utility lists internal storage (SSD/HDD) devices as well as USBs, and it gives me the option to read BIOS flash files from the internal storage as well. But when I confirm that I want to read it, it fails. Why must it only work from a USB?

1It fails how? – gronostaj – 2019-12-01T14:59:59.713
Doesn't really give me any details, just says "reading failed" or something like that – utaker – 2019-12-01T15:43:15.733
2What file system are these internal disk? In most cases the firmware can only read FAT32 in a case like this. While Linux can read NTFS it’s not a perfect implementation, likewise, FAT32 more or less is an fully documented standard. – Ramhound – 2019-12-01T19:39:13.970
I use my ESP on my UEFI system for the Asus update files. Since Ubuntu, I do have to change permissions to allow me to write to ESP. I have not used USB flash drive, but it would also have to be FAT32 to work with UEFI. – oldfred – 2019-12-02T00:14:57.430
