Instflop.dat

Hi,

I have downloaded the 91 mb ISO image of the QNX Realtime
Platform system and made a CD.

I have encountered a rather pathetic problem - I would like to
install QNX from a combination of floppy and CD and I followed
the instruction in the readme.txt file for copying the floppy
image, instflop.dat, onto the floppy.

However it doesn’t fit on an ordinary 1.44 floppy; I have tried
formatting the floppy with FAT 12, minix and ext2 but in
neither case can I get the instflop.dat to fit on the floppy.

I don’t have MS-Windows installed. Is that a prerequisite for
getting QNX to install?

Could someone please give me a hint on what to do here…?


Thanks,

Morten Bo Johansen

Sure it won’t fit, it is raw image of floppy. You should copy the raw
image to raw device on whatever OS you have. On Unix that could be ‘dd’
utility.

Oh, thanks! I’m blushing a little - but the readme.txt just
used “cp” so I thought I was meant to use that on Linux.

Thank you, I’ll try using dd!

Thank you, I’ll try using dd!

I’ve now used “dd” to create a QNX boot floppy and apparently
it was ok. but when booting with it things go wrong. I get the
following prompt followed by the dots and a lot of question
marks as the floppy drive itself starts to ßtutter". It looks
something like this:

press esc for alternate os…???.???..???


So I guess it wasn’t ok after all.

What I did was to format a floppy and then I used the command:

dd if=instflop.dat of=/dev/fd0 bs=1024 conv=sync ; sync

to create the floppy.


Could someone get me a little further?



Thanks,

I had tried with three floppies and none worked. On closer
scrutiny all proved to have bad sectors on them. So much for
floppy reliability.

Sorry for not checking better before posting. It works now.
