- a 'imageheader' of 256 bytes, followed by 'n' sectors of 256 bytes.
With this I would just have to put the Jasmin boot in DSK+256, the MicrodiscBoot at DSK+512, and the fake directory at DSK+768.
Unfortunately, I just checked on one my DSK, it does not seem quite right, it seems that if the disc title is MFMDISC, then there are additional synchro stuff between sectors, in the following format:
Code: Select all
F7 F7 4E 4E 4E 4E 4E 4E 4E 4E 4E 4E 4E 4E 4E
4E 4E 4E 4E 4E 4E 4E 4E 4E 4E 4E 4E 4E 4E 4E
4E 4E 4E 4E 4E 4E 4E 4E 4E 4E 00 00 00 00 00
00 00 00 00 00 A1 A1 A1 FE 29 01 10 01 F7 F7
Have you the exact format described somewhere, and how to detect the various variants, or at least just the general formula I can use to locate in the file a particular sector/track ?
Thanks
