OS9 Configuration

[UFO-OS9]

Hello,
I have been trying to create an image of an OS9 floppy for use on a Gotek with Flash floppy.
the Greaseweazle creates an image without errors & writes a floppy without errors, but the diskette & the image do not work in the OS9 unit. I assume this is due to my settings. ?

The working Gotek settings:
Microware OS-9 system requires jumper at S0 and the following lines in FF.CFG. Emulation will work with 1.6MB IMG files.
interface = ibmpc
host = akai
Hence I have been setting the GW format to Akai 1600 & 800 & others to no avail !

The manufacturers 1.6MB IMG file write parameters on their CMD line script, that writes OS9 images to floppy via a windows PC are:
diskrw A: W -t=80 -s=10 -b=1024 -f=E5 -n ... if this helps

But I cannot find a combination in GW that works.

Any help would be most appreciated, thanks for listening !

What command line are you using to generate the image using Greaseweazle? Can you zip the image file, and also a raw flux image file (eg. gw read my.scp), and attach to this ticket. Also include your FF.CFG file in the zip archive.

Hi Keirf,
I just reposted this in the discussions thinking this was the wrong place.. sorry.
I had no joy with the terminal , so I've been using the GUI which generates:
gw.exe read --format=akai.1600 --device=COM5 "C:\Users\User\Documents\GD-Service\Grease Weasel\Images\1.img"

Requested files attached:
Image-files.zip

Thanks for your help !

The scp file isn't really raw because --format akai.1600 is still on the command line. You need to get rid of that. Maybe there's a "no format" option somewhere in the GUI?

Another thing to consider: Is the Microware system and its cabling known good? Eg. Can you cross-check with a real floppy drive in the Microware system?

Thanks for the thought, but I checked the cabling & drive early on. Since then ...
I have successfully created an image file & used it on the Gotek. The parameters that I changed with reference to the manufacturers software CMD line (diskrw A: W -t=80 -s=10 -b=1024 -f=E5 -n) in the GUI were:
Cylinder sets 0-34, 35-80 (was 0-34, 35-79)
Bit rate : 1024
I still cannot write a floppy from the same image, but that's not a real problem as the whole purpose, was to create an image for use on the Gotek.
It would be nice to run it all in a terminal window but I cannot get gw.exe to start, it just flashes up a CMD window for a brief second & disappears.
Thanks for all your advice though !

I believe shift + right click in the greaseweazle folder, then select "Open command window here". Then that will open a command window where you can run gw.exe.
