[comp.unix.microport] microport SYS V/386 problems

henk@bebux.UUCP (Henk Dijkstra) (12/09/88)

Here are some questions about my microport system V/386:

I'm working with the uport software for about a year now and
generaly speaking i'm still very pleased with it.
However there are a few problems I still can't solve:

1) There seems to be no way to get printer control code's
   to the /dev/lp<whatever> device driver. Also the number
   of lines/page seems to be fixed at 66.
   (No lpset won't work - get : Attempting to enter debugger,
                                with no db module configured. )

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.

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.

Is there someone out there who experienced the same problems, and have
found a solution for it?
I would be very pleased to here from you. (Preferably by E-mail)

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.

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

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.
