Hello,
I have a copy of QNX v.4.24 which was purchased for use on a 66MHz 486
system, and ran on that system for a few years. I still have the manuals,
3 11/2 in. and 5 1/4 in floppies, and complete O/S, networking, C
compiler, QNX Windows and DOS emulator. I’d like to load them on a spare
PC, mainly for fun, and general hobby use.
My proiblem is that neither of the boot floppies will boot any of the
Pentium-class systems that I have. I have tried booting on a 166 MHz,
1966 vintage Pentium with 128MB of RAM, configured both as IDE and SCSI
system, with various card configurations right down top bare bones with
1MB SVGA card.
This system will boot and run anything else, from OpenDos 7.1 to Red Hat
Linux 7.3, as well as BeOS4.5 and 5.03 and Coherent without a bit of
trouble. But when I try to boot from the QNX 4.24 factory boot floppy, it
begins to boot, but invariably stops. Using the spinning boot arrow as
somew sort of guide to the boot’s progress, and hoping that its “stops”
mean completion of boot stages, I find that it always stops after
completing the twentieth or twenty-first “spin”. Both 3.5 inch and 5.25
inch floppies exhibit identical performance. Prior to now, the seal on
the factory 5.25 in. disks had never been broken;they were pristine,
My 266 MHz MMX box and 1900 MHZ Athlon-XP systems, both reliable, and
equally unfussy about booting anything short of the kitchen sink, behave
exactly the same. Can anyone make a suggestion about what’s going on here?
I’d really like to get this QNX4 setup going!
Oh, BTW, then I’ll start on another antique system with QNX2.13A…
Thanks in advance for any suggestions.
Best regards,
