address is stored at SDLSTL($230) and the high byte at› SDLSTL+1($231) for an example.› The next promt is - Scr drive [1-8]. Enter just the number of› the source drive.› Density [1-2] is the next promt. Enter 1 for single density› disks and 2 for true double density disks. DOS 2.5's enhanced› density calls for single density(1). Boot sector 1 is always› single density even on true double density disks.› Sector [1-411] This asks for the starting sector number to› disassemble, the number system is hexadecimal and $410 is equal to› 1040 decimal. › # of Sectors This prompt wants to know how many sectors to› disassemble. For our example, 1 is all that is necessary.› Offset [0-7F] This prompt wants to know the offset required.› It offsets the byte position by the number entered here. I have no› use for this so I always enter "0". If I ever need it I'll be glad› it's here. If you entered 3 here, then the third byte in the› sector would be listed as the first, and the first two would never› be seen.› Origin [0-FFFF] This prompt wants to know where to begin› counting address numbers. For sector 1, that is always $700.› Byt/Sec [7D/80] This prompt wants to know how many bytes per› sector you want to disassemble. For bootable disks and the boot› sectors 1-3 this is $80. For standard files it is $7D. Our› example will be 80.› Press the space bar before the text reaches the top of the› screen. Location $701 will contain the number of sectors to enter› into the diskmaster disassembler to disassemble your bootable disk.› Locations $702 and $703 contain the load address you will use as› the origin when you disassemble your disk. Almost all address› bytes are written in low byte, high byte reversed order. $00,$07› would be equal to $700 not $7. Location $711 will contain the› bytes/sec info. The sector# to disassemble your disk will be 1.›› FILE DISASSEMBLY›› There are only four prompts for file disassembly as most of› the pertinent data for disassembly is contained in the file› itself.› Disa Type [F/D] Enter (F) for File› Dest'N [E/P/Dn] E is for screen, P for printer, and Dn is for› COMPLETE filespec. (ie. D1:FILENAME.EXT). See tips for more on› disassembly to disk.› Labels [Y/N] See Labels above in the sector disassembly› section.› Source File The file you want to disassemble goes here.› Again FULL filespec (ie D1:FILENAME.EXT).›› TIPS ON DISASSEMBLY›› All input numbers are in hexadecimal›› If you would like to disassemble memory which Disk Master does› not do, you can always try to (K) Save Binary File using DOS, and› then disassemble that file.››› 5››
