devb-fdc problem in August RTP version

Hello all,

If I have an FAT floppy in drive and devb-fdc is up and running I can’t
mount the floppy anyway …

mount /dev/fd0 /fd -t dos
Guessing type [qnx4], use -t if incorrect
FSTAB: :No such file or directory


there is a bug in the first august version ?

I believe that should be

mount -t dos /dev/fd0 /fd

Docs say -t is optional and default is ‘qnx4’. That does not work - -t
is mandatory.

eh? I’ve mounted hard disk partitions successfully without the -t. Are
you saying that -t is required for floppies or in all cases?

I never was able to mount anything without explicitly setting -t.
Sometimes is even appears to work, but then it says fs is corrupted when
you try to access it.

Ok it is working, but when is mounting there are : led on and led off like
this:

mount -t dos /dev/fd0 /fd
then led on-off-on again … and 2 small sounds …

Is it normal ?
Otherwise eveything is fine mounted …

The driver is actually reading from the floppy to see if there is media
in the drive, and if so, whether it matches the file system type it
is expecting.

This causes the led to come on, and the heads to move back and forth causing
the noise.

Thanks for explanation.
BTW where could I find a list what laptops QNx is supporting with RTP ?

This would be difficult to do. Laptop makers change the
internal chips in a laptop on a frequent basis even though
the model number doesn’t change. The best thing to do is
find out what video, audio, etc. chipsets are used in the
laptop and compare them to our HW support list.

As Steve commented, this would be very difficult for us to do alone. The
number of laptop models is large, and many laptops available in North
America are not available worldwide, etc.

There is a new QNX friend however who is in the process of trying to
put a web page together with such a list on it. I hope he will read this
and comment here so you can contribute your experiences.

I can tell you however that I have heard many succes stories with DELL
DIMENSION 5000 series, and Toshiba Satellite series laptops.

If you wait a few days, I’m sure that many of our users will jump
in here with their own advice. Listen to them… they are better equipped
than I to make a suggestion. I’m just the team lead for graphics drivers…
they have actually purchased laptops.

I am using the Acer TravelMate 737TL and it works VERY well. Right now
there is a small issue with the PCCard (but since it has built in
ethernet I don’t even use it). The video support is great, so is audio.
I have not tried out the USB.
