Formatting a FAT12 floppy
Posted: Wed Jul 13, 2016 1:51 am
Hello!
I have a floppy emulated using a VFD.
Then I have a bootloader with OEM parameter block:
I assume, that if the floppy has a FAT12 file system it should be recognized by windows. But when i try to access it using windows explorer it says, that the floppy is not formatted. Am I missing something or is this normal?
Thanks for all the answers,
cyan
