if UIDE would check INT13/15 if change line is supported, and not
cache the floppy if it's not supported everything would be fine (and
/N5 not needed)
I can't locate any documentation about 0:448

I prefer software that works without switches. at least if it can
handle the situation itself.

wrong. VirtualBox tells you 'change line is not supported'
which part of this is difficult to understand ?

exactly. hands off these floppies.

neither BASELESS nor WRONG.
and neither accusations. just stating that they behave suboptimal.
