I do not install anything. I just boot up from diskette and use your sequence that you proposed to “warta”. I’ll copy it here.
If you boot off of a floppy, you must mount a driver. If the disk is an IDE drive, you might do the following:
$ mount disk 3 /drivers/disk.atc pa=qnx +v
This would use the AT (Cache) driver, and mount a QNX (Type 7) partition if it is found in the partition table. If this does not work, you can do things in two steps.
$ mount disk 3 /drivers/disk.atc +v
$ fdisk 3
Fdisk will show you what the partition table looks like. You could then mount a partition this way:
$ mount disk 3 d=3 pa=7 +v
There are other parameters in case you have two physical disks on the same controller.
There are other complications. QNX 2 never supported LBA mode, but I have a disk.ata driver that does. QNX 2 never (properly) supported 2 IDE controllers, but I have a way to do this also. QNX 2 did not support CD-ROM’s, so don’t even try. They use a different interface on top of the IDE interface called ATAPI which is not supported.
Once you think you have access to the disk you can check as follows:
$ ls 3:/
So with fdisk and ls I see correct partitition table and directory structure.
If i try to boot from HD i get
Boot Partition 1
And after it hangs.
