DISASM OS9 Module Disassembler disasm -m module name filename options Disasm was written to hack apart OS9 system modules,command modules, file managers and device drivers/descriptors either from memory or disk. Unlike most other disassemblers, disasm is a two pass disassembler, creating output using only referenced labels. This output can be redirected to a file and (after modifications if desired) then re-assembled. Disasm provides completely commented disassembly of Device Descriptors... very useful for building a customized boot file. disasm -m module name will link to module in memory - if not found,will load module from exec directory and then link to it...after disassembly,it will attempt to unlink the module. disasm pathlist/module name will 'read' the module from the specified path without loading. other options: o = display line number,address,object code & source code... useful for hard to crack modules with data embedded in the middle. x = look for module in execution directory. ANY combination of options is allowed (upper or lower case) but they *must* immediately follow the '-' and there must be no spaces separating the options. by changing relative address $17 from $64 to $30 will cause the output source to reference /d0/defs instead of /dd/defs also,if you are not using a driver which supports level II display codes, you *MUST* change relative address $15 from 01 to 00 to avoid problems in the event of an error message being printed out.
