For starters, use a media descriptor byte value of 0xFA in the BPB...
This may be a good

Der experts,
may I ask another question:
Is there a way to make FreeDos ignore that there is a floppy present upon
boot, i.e. force a boot from the harddrive? Again only a problem when running

On REAL (old) PC hardware, the existence of floppy disk changelines
is not guaranteed; even if the line is present AND properly connected

When DOS detects an unreliable floppy change line hardware,
it should use the floppy label / serial / similar to detect
changes in software ...
How does DOS ever detect that any hardware is unreliable??
I agree that it is nice to disable floppy caches, but maybe

I've never looked at UIDE closely, but there's always room for space

Maybe you should look again at the UIDE.ASM source file! I have
boiled down its logic
