Ich verstehe zwar kein Imperial aber könnte in bezug auf HD Floppys interessant sein.

This document contains a listing of mainboards and floppy controllers that
have been tested with my TESTFDC program to determine their capabilities. I
am hoping to grow this list, so please contribute your TESTFDC results for
boards not already listed here.
Usual disclaimers apply - I can make no guarantee that the information is
correct, additions and corrections are welcome.
----------------------------- Useful Information --------------------------
All mainboards should pass the 'D' tests - these are required for standard
PC formats.
A mainboard that fails all 'S' tests will not be able to read or recreate
single-density disks, which account for a significant portion of older non-
PC formats.
A mainboard that passes the 250 and 500kpbs 'S' tests, but fails the 300kbps
'S' test will not be able to handle single-density with a 1.2M 5.25" HD drive
(the most common 5.25" drive types in AT and later machines), however it will
be able to do it if you install a DD drive. (Use of a DD drive is recommended
for SD/DD formats anyway, even if the HD setup supports it).
The 'X' test (Double-Density with 128 bytes sectors) checks a capability that
is used by very few disk formats, and for most people, not having it will not
be a significant drawback. (Which is good, because the original NEC-765 PC
controller, and most later chips based on this design don't support it).
