Hi there, I am having a HUGE (yes, HUGE) problem using 4dos on my '386.
It all worked fine ..., until I installed OS/2 1.2 on my hard disk (with the
dual boot feature offcourse). The problem is that when I change a floppy
disk in one of the drives (A: = 1.44Mb, B: = 1.2Mb) 4dos doesn't recognise
this, ie. if I dir it, all I get is the directory of the previous disk. This
error goes even further : if I have NO disk inserted, I still get the same
directory (allthough it reads the drive). But this is not all! If a insert
a DD disk in the drive (and the previous was a HD disk) it reports a
general failure!. For this, there is no other solution, then to reboot and
to try again.
At first I thought that it was because of 4dos, but the problem still occurs
if I run COMMAND.COM as a secondary shell. Then I tried to start of from 
floppy (with 4dos installed), because I thought the boot sector of my HDD
could have been harmed by OS/2, but the problem still occured.

My configuration : 68Mb HDD one partition, with OS/2 and dos 4.01 installed.

My question : what has gone wrong, and what is the solution.

Note : I have had OS/2 and DOS 4.00 allready installed, and then the problem
didn't occur (this was IBM-DOS 4.00, now I am using MS-DOS 4.01).


Awaiting your responses,
