Does anyone know how to set the FDC cookie to enable HD format option in GEM ? There's a hint there was a FDC.PRG to do it but Google doesn't find much at all relating to it :(

Search for HDCOOKIE.PRG + ATARI via Google. Documentation for the _FDC content can be found here: http://toshyp.atari.org/en/003007.html

@Icky http://www.wrsonline.de/software/HDCOOKIE.LZH. ?

Thanks - I also found a few other PRGs on the Floppy Shop 5592 disk that allows me to play around with other cookies :)

Their version is HD_FDC.PRG - https://www.planetemu.net/rom/atari-st- ... floppyshop

Do any of them give you the HD format option in 206 tho ?

They create the _FDC cookie and as "_" is used for OS cookies, the OS uses this and adds the HD option in the format dialog, if the _FDC content is set properly. Check with a debugger/monitor program, if necessary ...

H4 with the 1.44HD GAL running Flashy Clock V3 to get TOS206 and HD_FDC.PRG to set the _FDC cookie.

That's something else to cross off the list then, nice one

:bravo:

@Icky Tried his flashy board with the same register patches and it does not work for him either, so I guess the good news is my board seems to be working correctly.

So it seems just accessing that register is just not enough for some reason :( it could be that TOS206 is at some point checking for a STE machine before it starts checking other things :shrug:

EDIT:
I tried scoping out that register to see if it was even being accessed, and it does not look like it , so anyone's guess to why this doesn't work then..
