How to read disk with QNX3.21 format under QNX6.x OS

Postby Xibei » Fri Nov 07, 2003 6:27 am

I have a data disk with QNX3.21 format, it can be mounted in QNX3.21 OS.

I want to copy the files in the QNX3.21 format disk to a DOS format disk, however, I can not mount a DOS disk in QNX3.21 OS.

So, I try to mount the QNX3.21 format disk on a QNX6.1 OS machine, I try "mount -t qnx4 fd0 /mnt/floppy" and "mount -t qnx2 fd0 /mnt/floppy" , but failed.

My Question:

1 How to mount a QNX3.21 format disk on QNX6.1 OS?

2 How to mount a DOS format disk on QNX3.21 OS?

QNX4 is NOT free. You have to buy it.

QNX 2 (even it is called 3.21, it is actually QNX2) has some DOS supports.

As far as supporting DOS, this is handled two ways. The DFS (DOS File
System) allows access to DOS disks and files as if they were QNX disks and files. Also, on selected compatibles, QDOS allows MS-DOS 3.20 and PC-DOS 3.1, 3.2 and 3.3 to be run as a single task under QNX.


so looks like DFS will work for you.

How to use dfs correctly?

Postby Xibei » Fri Nov 14, 2003 9:39 am

I run dfs under QNX3.21 OS , the command line is :

$ dfs start a=1

the system prompt: "Unable to create DFS administrator task--Administraor Program not found"

pls kindly tell me whether I must have the root administrator right to run the utility dfs.

And how to get the administrator right?

dfs is a licensed product. maybe you don't have the license installed?

there is a free mtools that people use to read/write DOS floppies in other Unix. see this for details: http://mtools.linux.lu/

JC has ported mtools to QNX2 and you can download it from quics:
