I did an update installation of 4.25 on top of 4.24. When completed I went
through the various ‘*.425’, comparing them to the 4.24 counterparts, and
resolved any differences. I set up a ‘/.boot’ with the identical content of
what was used for 4.24, and a ‘/etc/con fig/sysinit.1’. The only difference
between the 4.25 version of ‘sysinit.1’ and its 4.24 counterpart, is that I
set up this system as a single, non-networked node. This means that I
commented out the network lines.
After all was setup, I attempted a reboot off of the hard drive (HD), but it
hung up following the “Press ESC to select an alternate OS…” line. When I
boot off of the floppy boot disk, I was able to startup the ‘Fsys.eide’
utility, and mount the QNX partition. I even did a ‘chkfsys’ on the mounted
partition, but now I can’t seem to do anything.
I seem to be in a situation where the disk contains the information that I
need, but it’s not accessible either because the filesystem is setup
incorrectly, or because the controller is incorrect, etc. I’m at a loss: I
can’t execute any commands (chkfsys, ls, vi, etc.) because I can’t see the
‘/bin’ directory, and I can’t seem to get these commands from the boot
floppy. I’ve tried running through an update installation again, only to be
locked up where it tries to start ‘Fsys.eide’, that’s when I get repeated
“Waiting for /dev/hd0 to initialize.” messages until it times out.

After you have mounted the hard disk as:
mount -p /dev/hd0 /dev/hd0t77 /hd (or t78 if appropriate)
do:
prefix -R /=/hd/
This changes the root (/) to be the hard drive’s root. If the
disk is not fried, ls, vedit, etc. should work.
