Sorry, my confusion. I have used an Adaptec '1542B' (no F) bios copyright is
1988 (checksum BB00) with mcode copyright 1990 (checksum F3F7). I have read
and written mixed density images using the floppy portion of this
controller. This is a 16-bit ISA SCSI controller with a big 50 pin
centronics type connector on the bracket.
It might be more useful to know what kind of floppy chip it uses, rather
than what BIOS/uCode it has installed..

This may
or may not help, but I have used a 1542c with
imagedisk to create mixed density floppies. Others have
then used these to successfully create new images.
Interesting - I have a 1542 which does not work with
ImageDisk or TeleDisk/TESTSD
at single-density - the user reporting the problems also has
a 1542 which does not
work with any of the three programs ... Mine is a '1542CF' -
I assumed the 'F' ment
"with floppy" ... Is this the same as yours?
