Your question is not very clear. What is it you want to do? Duplicate the hard drive? It is unlikely that merely duplicating the disk will create a bootable QNX 2 hard drive. If the hard drives are identical, or if they have the same number of heads sectors/track it may work.
A DOS formatted disk is the same as a disk with no formatting to QNX. You can just write over the DOS formatting.
The process to make a bootable hard drive is not simple. Here is a brief summary.
- Mount the hard drive
- use fdisk to put a QNX partition on the drive
- mount the partition
- dinit the partition
- copy needed files to partition usually using “backup”
At this point, you need to have the new hard drive as the primary (not slave) drive on the primary controller. Since it probably wasn’t during the last 5 steps, you might need a bootable floppy disk. After booting the floppy you mount the hard drive.
- finally you run the boot command
If your system has serial ports or parallel ports in special locations, you might have to run osconfig before step 6.
