Thanks for the screen shots. It appears the raw copy went fine in terms of FDisk identifying the partitions and the boot partition (I have no idea if the data is correct but I suspect it is if you did a raw copy).
I notice your new drive is 1 terabyte in size. How old is your original machine? Some older machines could not handle drives that large. Perhaps that’s the problem? Do you have another newer machine to try in just in case (unless you have the motherboard specs for your old machine and can confirm it can handle drives that large)
@maschoen I can confirm there is no way to set the geometry. It’s a PC/104 embedded CPU with custom optimized BIOS.
@Tim the new drive is 1GB not 1TB. But I also try with a 128MB and 512MB CF.
I was thinking maybe I have to install directly QNX4 from the machine. I have a boot install floppy disk of QNX4. I tried to connect an old floppy reader and boot from it from the embedded machine. Even like this it doesn’t detect the CF… :
I see what the others have to say. But just because and old floppy install doesn’t work, may not mean anything if that version of QNX4 is older than the one you have on the CF.
What is curious is that it doesn’t even see an EDIE controller at all. It’s not missing the CF, it’s missing the entire controller. And this is the machine your original CF boots on? (if so, you are using a much newer version of QNX 4 on the CF than on the floppy).
What does the BIOS of that machine show (screen shot) when the CF is installed.
I’m not sure what you do with your QNX 4 system, however I thought I’d give myself a plug. As recently as two years ago I helped a customer convert a QNX 4 system so it would run on a VM. The original system ran with a dot matrix printer which was not available. I built them a spooler with a filter program that converted the dot matrix output into PCL for their laser printer. The point being, I’m a constractor and still am willing to program with QNX 4 if needed.
