iS-DOS "autoboot" trick: how?

Post by ketmar »

does anybody remember the trick iS-DOS used to "autoboot" on TR-DOS from non-standard disk format? i bet it is something with having a sector bigger than 256 bytes, which overwrites… something. of course, i can reverse it myself, but being old fat lazy fart i hope that somebody already did it, and wrote a guide (and maybe a demo). ;-)

btw, i know about "boot" file, that's not it. i need to create the disk which doesn't have TR-DOS on-disk structures at all, and it should automatically start my code. i know that it is not possible in TRD format, and i have to use UDI (or DSK), it's ok.

thank you! it is more than i had, but sadly, slightly less than i hoped. ;-) i totally forgot why TR-DOS has its buffer there, what memory map with TR-DOS is, what system vars will be corrupted, and so on. (not that i ever really wanted to know it, because i haet TR-DOS with a passion. ;-)

but it is a good starting point, so thank you a lot!
