Lpset is fixed in the latest version (3.0e). As a work around, make a raw devicenode for the printer like /dev/rlp with a major device number of 128 + the major
device number of /dev/lp.

->2) The 3 1/2 inch floppy drive (720 kB) is not working.
->   (It works fine when I boot msdos however).
->   With Unix: $ format /dev/rdsk/f0q9dt I get: Unkown minor dev. no 48 
->   (The f0d9dt (360 kB) driver works fine!)
->   So for the time being I've connected a 5 1/4 drive.

There was no support for 3.5" floppies in older releases. It's there and works
fine in 3.0e.

->3) With the dosmerge package I'm not able to create an EGA image
->   with the dosadmin command, on my TOP SEGA 800 (from TAXAN) card.
->   I get:  ega image build process failed.

That might never work. If the EGA BIOS is write protected or if it uses a banked
switching memory scheme then your stuck with CGA or MONO graphics under DOS.
