We were able to work around our problem by cloning the existing system’s
hard drive using the qnx_drive_copy script from the QNX free site. It worked
great with just a minor mod to the script.
However, it would still be interesting to figure out why the installation
process failed. We tried your suggestion, but the floppies with the copied
images failed in the exact same manner. The floppy drive is new, so maybe it
is a timing or compatibility issue with the new drive vs. the 4.1 driver.
The failure mode appears to be that the driver does not seem to realize that
a new floppy has been inserted; when you insert the second disk, the script
tries to read from the cache only, and gets the boot floppy data, which it
then considers corrupted. The data from the second disk is never actually
read from the drive.
11 years; hard to believe.
Anyway, thanks for the suggestions.

The first thinh I’d try is another drive in teh machine. the floppy
driver
has alwsy been very sensitive to timing so if either the disk, or the
drive
iare suspect you could have problems. QNX 4.1 is about 11 years old now
so
teh floppy couldbe bad too, you might see if you can do a raw copy to a
hard
disk of the floppy that is failing, then copy the image you get to a new
floppy and try the install again.

We have been trying to install QNX 4.1 from floppy, and have run into a
snag. The boot floppy boots, and the install script runs, but when
inserting
the installation disks, the process stops with a message indicating that
an
install disk is corrupted. The funny thing is, the message occurs
apparently
without the floppy being accessed, at least according to the drive
light.
It seems to me that I’ve encountered this before in the dim dark past,
but
I
can’t for the life of me remember when, or what the resolution was. Any
hints would be appreciated.
Thanks,
Kevin
