expansionoff 1.0 disable Zorro-II/III Expansions by software (C) 2019 Henryk Richter This tool can either mark expansions as invalid (Shutup flag) or remove them from the active expansion board list. Please note that this is in software only and won't help if the hidden (presumably broken) devices interfere with the operation of other boards. A more reliable way to disable Zorro devices would need to patch expansion.library, which is beyond the scope of this tool. compilation: m68k-amigaos-gcc expansionoff.c -o expansionoff -noixemul -Wall -s or sc expansionoff.c link
