Re: Help with dump QNX 1.2

That worked well, thanks :) It would be interesting to see the differences between this and the PCE converted images. Are your tool available to us mere mortals? BTW: If anyone is interested. Here are QNX version 0.4 and other versions of 2.x even on 360k. Unfortunately dumped by the same person / c...

Some bad tracks/sectors on dosfsys_ but they were unused.

But some of the disks show really bad issues of not spinning properly.
What tool would that be? 😱

Re: Help with dump QNX 1.2

S Anyway, I compared conversions using the SCP files as well, and it matches up enough to confirm it converted properly. So in my opinion, it is complete. BTW, anyone get that to run in PCE? When I tried it I just get a debugger error: "undefined operation [FE a0]" Thanks for that. I've s...

Re: Help with dump QNX 1.2

I used the tools included with the PCE emulator (PRI.EXE, PSI.EXE, and PFI.EXE) Here is an example of decoding a low density 360k image read with a 1.2mb drive: pfi track00.0.raw disk1.pfi pfi disk1.pfi -p double-step -R 1 -r 600000 -p decode pri disk1.pri pri disk1.pri -p decode mfm disk1.psi -f -...

Are you using HxC to convert to IMD or the psi tools?

Re: Help with dump QNX 1.2

The strange thing these original KF dumps where used to create a working boot image under PCE and 86Box. If there were damaged via the USB buffer problems how could they be used as working images under these emulation programs? Here is the zip with all the files. Copy protection was removed on these...

Re: Help with dump QNX 1.2

Here are the SCP dumps. Can anything be done with those? I've tried converting in HxC to KF raw and writing back to disk but seems to hang on boot up. disks cant be read in MSDOS this could be because of the file system type?

Re: Help with dump QNX 1.2

I was able to decode these mostly OK with the PCE emulator tools. There were some bad sectors in "qnx12_dosfsys_" but they were all in the blank area. Did you manage to write back to floppy and test if it works? Unfortunately I don't hold the originals so I can't re-dump this. It was hard...

Re: Help with dump QNX 1.2

Best use the first compressed file I sent you originally: qnx12-kryoflux-raw.rar This has the original raw files in it. I might have messed with the second image I sent you.
