i’m searching for a QNX 1.01 Boot Image. This image should be able to formate my harddisk with QNX 1 filesystem. Otherwise i need some program that can format my hdd with the QNX 1 filesystem.
Do you know any solution?
Please help!


QNX 1 huh? I don’t think it ever was commercialised? Mitchell?

There absolutely was a QNX 1. My first version was a pre-release .43. It was not multi-tasking. It strangely used 256 byte sectors on the floppy. This was quickly changed to 512 in later versions. I think there might have been a .9 or .99 version, and then eventually a 1.0 version. This was the first multi-tasking version. At that point the major revisions were 1.1 and 1.2. These all ran in real mode, there being no protected mode on the Intel 8088. Then IBM came out with the AT (80286) computer. QNX came out with a 2.0 version that had two nice features, support for protected mode, and the Network. I’m sure my details are a little sketchy here. I once wrote up a history, which QSSL helped to correct, and I think it is around somewhere in a FAQ.

There are only two likely places someone would find a QNX 1 boot diskette. Me and QSSL. I really doubt QSSL will give you one. I don’t think I have one other than the .43 version I kept for curiosity. As far as I know it only works on an IBM PC (8088) and only supports single sided floppy disks 180K (although it might work on dual sided drives). There is no hard drive support of course. The system is curious, but almost useless. If I did have such a version it would probably be 1.2x. I’d need a really strong argument to even go look for it, and I’d have to ask QSSL what they thought first.

A note on hard drives. Version 1.01 most definitely did not have any hard drive support of interest. There were two early disks that were supported. The more economical one was from Davong with 5MB and later a 10MB disks. The 5MB drive cost $2000, a bargain. I bought one and used it for many years. Davong provided a custom controller (the only standard at the time was SCSI 1.0 and it wasn’t all that standard). There was no mount command, this came later. The driver had to be melded into the boot image with a special program. I can’t recall the name of the other drive, maybe Corvus? but it came in 5/10/20 MB versions. The 5MB version was $3000. Support for the IBM AT hard drive only came with version 2.0. This standard later evolved into IDE and then EIDE. I think we called it an AT controller and hard drive.
The next disk that was available was with a driver I wrote. It was for an Iomega Bernoulli Box. This was a dual 10MB cartridge drive. The cartridges held 8 inch floppy disks. The controller was called a PC0. There was no way to boot off of this disk. It was a SCSI 1.0 drive/controller, but as I mentioned, this was not much of a standard.

I highly doubt that there are any remaining functioning hard drives from this era.

So it sounds like the author of this thread is at least a little confused.

Hello and thanks for this information.
I think, it must an error be present here. It is fact that I have software for an engine controller, which was provided still with neutrino 1.01. Possibly it can be that the QNX version is not correct completely, but it is like that this program runs as test version on a hdd under QNX. There in neutrinos 1.01 unfortunately still different methods were used to use FlashDeviceDriver I think, that I need also the correct operating system to replace the old HDD. If this is wrong, I can be instructed gladly a better, however are that the things, which I know about the system.
Thanks for help!

I don’t really recall Neutrino having a version 1.01, but it is possible.
I’m not the best authority on this. What I do remember is that the first
version of Neutrino I worked with was hosted only from QNX 4.
The compiler was the Watcom 10.6 compiler.

Ouch that will be very tricky to find. I have worked on neutrino 1 before but that was a long time ago 6-7 years. Doubt any one around here has an image. Even if we would it would be illegal to provide it to you. Your best bet is to contact QSS.
