THE AUTOBOOT TOOL..THE BOOT SECTOR IS A FEATURE WHICH IS SUPPOSED TO LAUNCH SOFT WARE OFF THE DISK AS SOON AS THE COMPUTE R IS POWERED UP OR RESET. HOWEVER, USIN G THIS HANDY FEATURE FOR YOUR OWN PURPOS ES HAS BEEN VERY DIFFICULT. THE AUTOBOO T TOOL CONSISTS OF SEVERAL MODULES WHICH MAKES CREATION AND MANIPULATION OF BOOT SECTORS QUICK AND EASY. PLEASE NOTE TH AT USING THE SERVANT, A BOOT SECTOR MAY BE CREATED AND EXECUTED ON A DISK DRIVE OF ANY DEVICE NUMBER...SPECIAL NOTE TO 1 581 USERS: USING THE AUTOBOOT TOOL, THE ROOT DIRECTORY WILL BE AUTOMATICALLY SE LECTED. A BOOT SECTOR CANNOT EXIST UNDE R A SUBDIRECTORY...ANALYZE BOOT SECTOR:. THIS FEATURE WILL DECODE THE BOOT SECTOR AND DISPLAY ITS RESULTS ON THE SCREEN. FIRST, IT INDICATES IF A BOOT SECTOR IS PRESENT, IF THE BOOT SECTOR IS OCCUPIED BY A FILE, OR IF A "KILLED" BOOT SECTOR IS PRESENT. IF A BOOT SECTOR EXIST, YO U'LL BE WARNED IF IT IS NOT PROTECTED FR OM OVERWRITING (NOT PROTECTED BY BAM). IN THAT CASE USE THE PROTECT SECTOR(S) F EATURE TO PROTECT IT IF DESIRED. IF A B OOT SECTOR OR KILLED BOOT SECTOR EXISTS, THE FOLLOWING INFORMATION IS PROVIDED:. .1) ADDITIONAL BOOT SECTORS INFO. THE C 128 BOOT SYSTEM INCLUDES AN OPTION TO RE AD ADDITIONAL BLOCKS OFF THE DISK AS PAR T OF THE BOOT AREA. THESE EXTRA SECTORS STARTS AT TRACK 1, SECTOR 1, AND CONTIN UE ONWARD FROM THERE. A TOTAL OF 255 EX TRA BOOT SECTORS CAN BE SPECIFIED, MAKIN G THE BOOT AREA USE SEVERAL WHOLE TRACKS . THE C128 BOOT FEATURE MAKES IT POSSIB LE TO PLACE THESE EXTRA BLOCKS ANYWHERE IN THE COMPUTER'S MEMORY. HOW MANY EXTR A BLOCKS TO BE LOADED, THE ADDRESS AND M EMORY BANK WHERE THEY ARE PLACED ARE DIS PLAYED..2) LOAD PRG FILE: A FILE NAME C AN BE SPECIFIED IN THE BOOT SECTOR, AND IF PRESENT, A PRG FILE OF THAT NAME IS L OADED INTO BANK 0 RAM. THE LOAD ADDRESS IS DETERMINED BY THE LOAD ADDRESS OF TH E PROGRAM ITSELF. THE FILE NAME (IF ANY ) WILL BE DISPLAYED ALONG WITH THE LOAD ADDRESS. THE LOAD ADDRESS MUST BE SOUGH T IN THE FILE ITSELF, AND IF THE FILE CA N'T BE READ, A DOS ERROR MESSAGE IS DISP LAYED INSTEAD OF THE LOAD ADDRESS..3) ML CODE START: THE BOOT SECTOR MUST CONTA IN SOME ML CODE TO DETERMINE WHAT THE BO OT SECTOR IS SUPPOSED TO DO. IT MAY BE A SIMPLE JMP INSTRUCTION (SIMILAR TO BAS IC SYS), OR AN ELABORATE ML PROGRAM. TH E START ADDRESS OF THE ML CODE IS NOT FI XED; IT IS DETERMINED BY THE LENGTH OF T HE BOOT MESSAGE (SEE BELOW) AND FILE NAM E (ABOVE). THE START ADDRESS IS DISPLAY ED AS AN OFFSET FROM THE START OF THE BO OT BUFFER IN THE COMPUTER'S MEMORY. THE BOOT BUFFER IS AT ADDRESS 2816 ($0B00) IN BANK 0. TO CALCULATE THE REAL START ADDRESS OF THE ML CODE, ADD THIS NUMBER TO THE OFFSET VALUE..4) BOOT MESSAGE: A N OPTIONAL MESSAGE CAN BE DISPLAYED WHEN A BOOT IS PERFORMED (BOOT XXXX ...). O FTEN, THE NAME OF THE PROGRAM TO BE BOOT ED IS DISPLAYED, BUT THE MESSAGE MAY CON TAIN JUST ABOUT ANYTHING. THE MESSAGE M AY CONTAIN CONTROL CODES WHICH IS (BY TH E BOOT SECTOR ANALYZER) DISPLAYED AS RVS CHARACTERS..5) COMMAND LINE: UNLIKE TH E OTHER INFORMATION ON THE ANALYZER SCRE EN, THIS IS NOT AN INHERENT FEATURE OF C 128 BOOT SECTORS. RATHER, BY USING A SMA LL PIECE OF ML CODE, IT IS POSSIBLE TO E XECUTE A BASIC COMMAND LINE. THE SERVAN TS AUTOBOOT TOOL CONTAINS A PROVISION FO R CREATING A COMMAND LINE OF YOUR OWN FA NCY. SINCE THIS IS THE KIND OF BOOT SEC TORS YOU ARE PROBABLY MOST OFTEN GOING T O CREATE YOURSELF, THE BASIC COMMAND LIN E (IF FOUND) IS INCLUDED HERE. INCIDENT ALLY, THE SAME METHOD IS USED BY THE "AU TOBOOT MAKER" INCLUDED ON THE TEST/DEMO DISK SUPPLIED WITH COMMODORE DISK DRIVES ...HIT ANY KEY TO RETURN TO THE AUTOBOOT TOOL MENU...DUMP SECTOR:.DISPLAYS THE C ONTENTS OF TRACK 1 SECTOR 0 AS ASCII CHA RACTERS, REGARDLESS IF IT CONTAINS A BOO T SECTOR OR NOT. CONTROL CHARACTERS ARE DISPLAYED AS RVS CODES. A BOOT SECTOR HAS THE LETTERS "CBM" AS THE THREE FIRST CHARACTERS. THE DUMP FEATURE MIGHT BE USEFUL FOR REVEALING THINGS ABOUT A BOOT SECTOR THAT WOULD OTHERWISE BE DIFFICUL T TO DISCLOSE. ALSO, IF THE BOOT SECTOR IS BLOCKED BY A PROGRAM, YOU MIGHT BE A BLE TO IDENTIFY THE PROGRAM WHICH CAUSES THE INTERFERENCE...HIT ANY KEY TO RETUR N TO THE AUTOBOOT TOOL MENU...MAKE BOOT SECTOR:.THE OBJECTIVE HERE IS TO CREATE A DIRECT MODE BASIC PROGRAM LINE TO BE E XECUTED UPON BOOTING. ALL IMMEDIATE MOD E BASIC COMMANDS CAN BE USED, AND THE PO SSIBILITIES ARE LIMITED BY IMAGINATION A ND THE SIZE OF THE BOOT SECTOR...UPON SE LECTION OF CREATE FROM THE AUTOBOOT TOOL MENU, YOU'RE WARNED IF A BOOT SECTOR IS ALREADY PRESENT ON THE DISK, OR IF THE BOOT SECTOR IS TAKEN BY A PROGRAM OR OTH ER DATA. IF YOU WISH TO PRESERVE AN ORI GINAL BOOT SECTOR, PLEASE USE THE BOOT T O FILE FEATURE FIRST...ENTERING THE BOOT MESSAGE:.OPTIONALLY, YOU CAN ENTER A ME SSAGE TO BE DISPLAYED UPON BOOT (BOOTING XXXX ...). THERE ARE A TOTAL OF 239 C HARACTERS AVAILABLE FOR THE BOOT MESSAGE AND COMMAND LINE. EVERY CHARACTER OF T HE BOOT MESSAGE WILL STEAL SPACE FROM TH E COMMAND LINE. JUST PRESS RETURN WITHO UT ENTERING ANYTHING IF YOU DON'T WANT A BOOT MESSAGE...PLEASE NOTE THAT YOU ARE NOT LIMITED TO PLAIN TEXT; CONTROL CHAR ACTERS MAY ALSO BE USED. PLEASE REFER T O APPENDIX F FOR AN OVERVIEW OF THE CONT ROL CHARACTERS AND HOW THEY ARE ENTERED. ALSO PLEASE NOTE THAT YOUR COMPUTER IN MOST CASES WILL BE IN UPPERCASE/GRAPHIC S MODE (ALIAS "CURSOR UP" MODE) WHEN THE BOOT MESSAGE IS DISPLAYED. TEXT ENTERE D AS LOWERCASE WILL APPEAR AS UPPERCASE, AND UPPERCASE CHARACTERS WILL APPEAR AS GRAPHIC SYMBOLS. YOU MAY CIRCUMVENT TH IS BY ENTERING A RVS N AS THE FIRST CHAR ACTER. THIS WILL PUT THE COMPUTER INTO LOWERCASE MODE (ALSO CALLED "CURSOR DOWN " MODE) WHEN THE BOOT SECTOR IS EXECUTED ...PLEASE NOTE: NEVER USE A RVS @ IN YO UR BOOT SECTORS. A RVS @ WILL YIELD AN ASCII CODE OF ZERO WHICH WILL EFFECTIVEL Y TERMINATE THE STRING OR COMMAND LINE. MALFUNCTION WILL BE INEVITABLE...ENTERI NG THE COMMAND LINE:.THIS IS JUST LIKE E NTERING A COMMAND LINE IN THE BASIC IMME DIATE MODE. SEVERAL COMMANDS CAN BE USE D, SEPARATED BY COLONS. LOOPS CAN BE CO NSTRUCTED USING FOR-NEXT OR DO-LOOP/EXIT . DECISIONS CAN ME MADE USING IF/THEN/E LSE. PLEASE NOTE THAT YOU ARE NOT RESTR ICTED TO THE 160 CHARACTER LIMIT ALLOWED BY THE BASIC SCREEN EDITOR. 239 CHARAC TERS IS AVAILABLE, MINUS THE LENGTH OF T HE BOOT MESSAGE (IF ANY). YOU MAY USE A BBREVIATED BASIC COMMANDS IF NECESSARY. OF COURSE, THE BASIC COMMANDS YOU ARE G OING TO USE MOST OFTEN IS BOOT "FILENAME " BLOAD "FILENAME", SYS AND RUN "FILENAM E"...IT IS IMPORTANT TO USE GOOD SENSE W HEN CONSTRUCTING A COMMAND LINE. REMEMB ER THAT YOU ARE LIMITED TO BASIC COMMAND S LEGAL IN IMMEDIATE MODE. THIS MEANS T HAT INPUT, INPUT#, GET AND GET# ARE OUT. READ/DATA, GOTO AND GOSUB WON'T WORK B ECAUSE THE COMMAND LINE DON'T CONTAIN LI NE NUMBERS...ALSO BE CAREFUL WHEN USING IF-THEN. THE COMMAND LINE AFTER THE THE N STATEMENT WILL BE EXECUTED ONLY IF THE CRITERIA SET IN THE IF STATEMENT IS TRU E. LET'S SAY THAT YOU WANT TO SET FAST MODE IF THE COMPUTER IS BOOTED WITH THE 80 COLUMN SCREEN ACTIVE AND THEN RUN A P ROGRAM. YOU MIGHT TRY THIS:..IF RGR (0) =5 THEN FAST:RUN "PROGRAM"..THIS WILL SE EM TO WORK PERFECTLY IN 80 COLUMNS, BUT THE PROGRAM WON'T BE RUN IN 40 COLUMNS, WHY? THE COMMANDS AFTER THEN WILL BE EX ECUTED ONLY IF THE CONDITIONS IN THE IF STATEMENTS IS TRUE. THE LINE BELOW WILL CURE THE PROBLEM:..IF RGR (0)=5 THEN FA ST:RUN "PROGRAM":ELSE RUN "PROGRAM"..YOU MUST TELL THE COMPUTER THAT YOU WANT TO RUN THE PROGRAM WHETHER OR NOT THE 80 C OLUMN SCREEN IS ACTIVE. AGAIN, PLEASE N OTE THAT ANY COMMANDS FOLLOWING A ELSE S TATEMENT WILL BE EXECUTED ONLY OF THE CO NDITIONS IN THE IF STATEMENT IS FALSE. THIS MEANS THAT IF SEVERAL COMMANDS IS T O BE EXECUTED IN EITHER CASE AFTER AN IF -THEN COMMAND, THEY MUST ALL BE INCLUDED TWICE; ONCE AFTER THE THEN COMMAND, AND ONCE AFTER THE ELSE COMMAND. OF COURSE , YOU MAY CONSIDER WRITING A NORMAL BASI C PROGRAM WHICH IS RUN BY A SIMPLE RUN " FILENAME" COMMAND IN THE BOOT SECTOR...C ONTROL CODES MAY BE ENTERED AS PART OF T HE COMMAND LINE, BUT ONLY INSIDE QUOTES. CONTROL CHARACTERS OUTSIDE QUOTES WILL INVOKE A SYNTAX ERROR. YOU MAY NOTICE THAT TYPING A QUOTE CHARACTER WON'T INV OKE "QUOTE MODE". RATHER, IF YOU WANT T O INCLUDE CURSOR CONTROL, INSERT, DELETE , HOME, CLEAR OR RETURN CODES, HOLD DOWN ALT AND PRESS THE APPROPRIATE KEY. ALS O PLEASE READ APPENDIX E...WHEN THE COMM AND LINE IS ENTERED, PRESS RETURN TO WRI TE YOUR BOOT SECTOR TO DISK. BEFORE DOI NG SO HOWEVER, THE COMPUTER WILL ASK YOU IF ITS OK TO PROCEED...TRICKS AND TIPS: .YOU MAY FIND IT VERY USEFUL TO BE ABLE TO BOOT A PROGRAM FROM ANY DISK DRIVE. PEEKING ADDRESS 186 WILL ENABLE YOU TO D O SO. WHEN THE BOOT SECTOR IS EXECUTED, THIS LOCATION WILL HOLD THE DEVICE NUMB ER USED. FOR EXAMPLE RUNNING A BASIC PR OGRAM FROM ANY DISK DRIVE IS DONE LIKE T HIS:..RUN "PROGRAM",U(PEEK(186))..PLEASE NOTE THE USE OF PARENTHESES. THE PEEK COMMAND MUST BE ENCLOSED IN PARENTHESES FOR THE U SPECIFIER TO WORK...ALL SOFTWA RE MIGHT NOT BE ABLE TO RUN OFF ANY OTHE R DISK DRIVE THAN DEVICE 8. TO CIRCUMVE NT THIS SLOPPY PROGRAMMING PRACTICE, YOU MAY SIMPLY CHANGE OR SWAP DEVICE NUMBER S. PLEASE REFER TO YOUR DISK DRIVE MANU AL FOR THE COMMAND SEQUENCE NEEDED. SWA PPING DEVICE NUMBERS, SAY BETWEEN DEVICE NUMBERS 8 AND 9 IS DONE BY TEMPORARILY SETTING DEVICE 9 TO, SAY, 30, CHANGING D EVICE 8 TO 9, AND THEN CHANGING THE DISK DRIVE NOW USING DEVICE NUMBER 30 TO 8.. .EDIT COMMAND LINE:.YOU MAY WANT TO EDIT A COMMAND LINE BOOT SECTOR FOR DEBUGGIN G PURPOSES OR OTHER REASONS. THE BOOT S ECTOR WILL BE READ OFF THE DISK AND A CH ECK IS MADE TO ESTABLISH IF A VALID BOOT SECTOR REALLY EXIST AND THAT IT CONTAIN S A COMMAND LINE. IF EVERYTHING IS FOUN D TO BE OK, EDITING THE COMMAND LINE IS JUST LIKE CREATING IT FOR THE FIST TIME. PLEASE REFER TO THE SECTION ABOUT CREA TION OF A BOOT SECTOR ABOVE. THE BOOT M ESSAGE CANNOT BE EDITED...RUN/64 BOOT SE CTOR:.THIS SELECTION WILL CREATE A BOOT SECTOR WHICH WILL LOAD A 64 MODE PROGRAM INTO COMPUTER MEMORY, SWITCH TO 64 MODE , AND RUN IT. IF YOU HAVE A 1571 OR 158 1 DISK DRIVE, THE 128 BURST LOAD WILL BE ACTIVE, AND WILL LOAD YOUR PROGRAM MANY TIMES FASTER THAN IN 64 MODE. THE PROG RAM TO BE LOADED MUST BE A BASIC PROGRAM OR A ML PROGRAM WHICH IS STARTED WITH A RUN COMMAND...THE BOOT SECTOR WILL WORK WITH DRIVES OF ANY DEVICE NUMBER. HOWE VER, THE PROGRAM YOU LOAD MIGHT NOT ME A BLE TO DO THIS...PLEASE NOTE THAT THE BO OT SECTOR CAN'T SAFELY HANDLE PROGRAMS B IGGER THAN 153 BLOCKS. HOWEVER, IT IS W ORTH TRYING BIGGER PROGRAMS, AS THEY MAY VERY WELL WORK, ESPECIALLY PROGRAMS OF UP TO 201 BLOCKS. THE BOOT SECTOR CAN'T HANDLE LARGE PROGRAM AS WELL AS THE MAI N MENU C64 OPTIONS BECAUSE OF MEMORY CON STRAINTS. SOME RAM UNDER THE 64 MODE RO MS AND I/O IS CORRUPTED DURING SETUP OF THE 64 MODE...YOU WILL BE WARNED IF A BO OT SECTOR IS ALREADY PRESENT ON THE DISK , OR IF THE BOOT SECTOR IS TAKEN BY A PR OGRAM OR OTHER DATA...BESIDES ENTERING T HE FILE NAME TO BE LOADED, YOU ARE ASKED IF YOU WANT TO RESET THE 1571 DRIVE. R ESETTING THE 1571 WILL SWITCH IT TO 1541 MODE WHICH MAY ME NECESSARY TO RETAIN C OMPATIBILITY WITH THE SOFTWARE YOU ARE U SING. IF YOU WANT TO ENJOY THE DOUBLE S IDED MODE ON THE 1571 IN 64 MODE, SELECT NOT TO RESET THE DRIVE. IF YOU HAVE JI FFYDOS INSTALLED IN YOUR SYSTEM, YOU SHO ULD RESET THE DRIVE IN ANY CASE, SINCE J IFFYDOS WILL BE ACTIVE ONLY IF THE DRIVE IS OPERATING IN 1541 MODE, WHILE STILL BEING ABLE TO USE DOUBLE SIDED DISKS. I F YOU ELECT TO RESET THE 1571 AND THE DI SK IS LATER BOOTED FROM ANOTHER DRIVE TY PE, THE ERROR LIGHT WILL FLASH. HOWEVER , THIS IS WITHOUT HARMFUL SIDE-EFFECTS.. .YOU WILL BE ASKED IF IT IS OK TO PROCEE D, AND THE BOOT SECTOR WILL THEN BE WRIT TEN TO DISK...LOAD "",X,1/64 BOOT:.THIS SELECTION WILL CREATE A BOOT SECTOR THAT SWITCHES THE COMPUTER TO 64 MODE, AND T HEN PERFORMS A LOAD COMMAND SIMILAR TO L OAD "PROGRAM",8,1. YOU ARE NOT REQUIRED TO USE DEVICE 8 HOWEVER, THE BOOT SECTO R WILL WORK WITH ALL DEVICE NUMBERS. TH E SOFTWARE YOU ARE USING MIGHT NOT BE AB LE TO WORK WITH SUCH VARIETY OF DEVICE N UMBERS THOUGH. THE BOOT SECTOR CAN HAND LE PROGRAMS OF UP TO 201 BLOCKS...YOU WI LL BE WARNED IF A BOOT SECTOR IS ALREADY PRESENT ON THE DISK, OR IF THE BOOT SEC TOR IS TAKEN BY A PROGRAM OR OTHER DATA. ..YOU WILL BE ASKED TO ENTER A FILE NAME TO BE LOADED BY THE BOOT SECTOR CODE. OPTIONALLY, YOU MAY ALSO ENTER A COMMAND LINE OF UP TO 12 CHARACTERS TO BE EXECU TED AFTER THE PROGRAM HAS BEEN LOADED. TYPICALLY, YOU WOULD USE RUN OR SYS TO S TART THE PROGRAM. PLEASE NOTE THAT YOU DON'T HAVE TO ADD A RETURN CHARACTER TO THE COMMAND, THE BOOT SECTOR WILL EXECUT E THE COMMAND LINE AUTOMATICALLY. IF TH E PROGRAM IS AUTO-RUNNING, MEANING THAT IT RUNS BY ITSELF WITHOUT THE NEED FOR A RUN OR SYS CALL, PRESS RETURN WITHOUT E NTERING ANYTHING...YOU'LL ALSO BE ASKED IF YOU WANT TO RESET THE 1571 DRIVE. RE SETTING THE 1571 WILL SWITCH IT TO 1541 MODE WHICH MAY ME NECESSARY TO RETAIN CO MPATIBILITY WITH THE SOFTWARE YOU ARE US ING. IF YOU WANT TO ENJOY THE DOUBLE SI DED MODE ON THE 1571 IN 64 MODE, SELECT NOT TO RESET THE DRIVE. IF YOU HAVE JIF FYDOS INSTALLED IN YOUR SYSTEM, YOU SHOU LD RESET THE DRIVE IN ANY CASE, SINCE JI FFYDOS WILL BE ACTIVE ONLY IF THE DRIVE IS OPERATING IN 1541 MODE, WHILE STILL B EING ABLE TO USE DOUBLE SIDED DISKS. IF YOU ELECT TO RESET THE 1571 AND THE DIS K IS LATER BOOTED FROM ANOTHER DRIVE TYP E, IT WON'T PRODUCE ANY SIDE-EFFECTS...Y OU WILL BE ASKED IF IT IS OK TO PROCEED, AND THE BOOT SECTOR WILL THEN BE WRITTE N TO DISK...BOOT TO FILE:.THIS FEATURE R EADS THE BOOT SECTOR OFF A DISK AND SAVE S IT AS A PRG FILE. IT MIGHT BE USEFUL TO USE THE PRG FILE AS A BACKUP COPY OF THE BOOT SECTOR, ESPECIALLY IF YOU WANT TO REPLACE THE ORIGINAL BOOT SECTOR. PL EASE NOTE THAT ONLY TRACK 0, SECTOR 1 WI LL BE SAVED. MULTISECTOR BOOT AREAS CAN 'T BE SAVED BY THIS UTILITY. IF IN DOUB T, PLEASE USE THE ANALYZE BOOT SECTOR OP TION TO SEE IF ADDITIONAL BOOT SECTORS A RE PRESENT...THE FILE CREATED BY THIS UT ILITY WILL BE FULLY EXECUTABLE. THAT IS , RATHER THAN BOOTING THE DISK, YOU MAY NOW BOOT THE PRG FILE:..BANK 15:BOOT "BO OTFILE"..SOMETIMES, THIS APPROACH WON'T WORK. PLEASE ANALYZE THE BOOT SECTOR YO U ARE GOING TO CONVERT AND SEE IF A PRG FILE IS LOADED BY THE BOOT SECTOR. TO M AKE THE BOOTFILE WORK IS SUCH CASES, USE THE FOLLOWING COMMAND SYNTAX:..BLOAD "P RGFILE",B0:BANK 15:BOOT"BOOTFILE"..THE A BOVE COMMANDS MAY EASILY BE USED AS PART OF THE COMMAND LINE IN A CUSTOM BOOT SE CTOR CREATED BY THE CREATE UTILITY. FOR EXAMPLE, YOU MAY WANT TO SEND COMMANDS TO A PRINTER INTERFACE OR CHANGE DISK DE VICE NUMBERS BEFORE BOOTING YOUR SOFTWAR E. PLEASE NOTE THAT A BOOTFILE WILL OVE RWRITE THE BOOT SECTOR IN THE COMPUTER'S MEMORY WHEN EXECUTED. IT IS THEREFORE NOT POSSIBLE FOR A CUSTOM BOOT SECTOR TO LOAD OR BOOT A BOOTFILE AND THEN RETURN FOR FURTHER BASIC COMMANDS. THIS CONDI TION WILL INVOKE A SYNTAX ERROR, OR COUL D EVEN CRASH THE SYSTEM. THE EXECUTION OF THE BOOTFILE SHOULD BE EXECUTED LAST IN A CUSTOM BOOT SECTOR COMMAND LINE...T HE TRANSFER PROCESS BEGINS BY READING TH E BOOT SECTOR OFF THE DISK IN THE DRIVE. YOU'LL THEN BE PROMPTED FOR A FILE NAM E, THEN THE TARGET DISK, A DISK WHERE TO STORE THE RESULTING FILE. THE TARGET D ISK MUST BE PUT INTO THE SAME DRIVE THAT WAS USED TO READ THE BOOT SECTOR...FILE TO BOOT:.TO DO THE REVERSE OF THE ABOVE , USE THIS UTILITY. A PRG FILE IS READ FROM DISK AND ITS CONTENTS IS PLACED IN THE BOOT SECTOR. THE COMBINATION OF THE BOOT TRANSFER UTILITIES MAY BE USED FOR ARCHIVAL PURPOSES OR FOR TRANSFERRING B OOT SECTORS BETWEEN DISSIMILAR DRIVE TYP ES. THE UTILITY CAN'T HANDLE MULTISECTO R BOOT AREAS, FILES LARGER THAN 256 BYTE S IS TRUNCATED...THIS UTILITY MAY EQUALL Y WELL BE USED TO ENABLE A BOOT SECTOR E NTIRELY OF YOUR OWN DESIGN, WHERE YOU YO URSELF HAVE WRITTEN THE ML CODE. A PRG FILE TO BECOME A BOOT SECTOR MUST HAVE T HE FOLLOWING STRUCTURE:..1) 7 ZERO BYTES . ACTUALLY, THE THREE FIRST BYTES SHOUL D CONTAIN THE ASCII CHARACTERS "CBM", BU T THESE ARE AUTOMATICALLY PROVIDED BY TH E TRANSFER UTILITY. YOU MAY SUBSTITUTE THE THREE FIRST BYTES WITH A JMP INSTRUC TION TO THE START OF THE ML CODE FOR DEB UGGING PURPOSES. INCIDENTALLY, THIS IS WHAT THE TRANSFER BOOT TO FILE UTILITY D OES..2) OPTIONAL BOOT MESSAGE (BOOT XXXX ....). ALL CBM ASCII CHARACTERS CAN BE USED AND THE LENGTH OF THE STRING IS LI MITED ONLY BY THE SIZE OF THE BOOT SECTO R..3) ONE ZERO BYTE (REGARDLESS IF YOU I NCLUDE A BOOT MESSAGE OR NOT)..4) OPTION AL PRG FILE TO LOAD. IF YOU PROVIDE A F ILE NAME AT THIS POINT IT WILL BE LOADED INTO BANK 0 MEMORY (SIMILAR TO BLOAD "F ILE",B0), BUT IT WILL NOT BE CALLED. AN Y CALL ADDRESS MUST BE PROVIDED IN THE M L CODE (SEE BELOW)..5) ONE ZERO BYTE (RE GARDLESS IF YOU PROVIDE A FILE NAME OR N OT)..6) ML CODE. THIS IS NORMAL 6502 ML CODE...THE EXACT START OF THE ML CODE W ILL BE DETERMINED BY THE LENGTH OF THE B OOT MESSAGE AND/OR FILE NAME, IF ANY. I N ITS SIMPLEST FORM, A BOOT SECTOR MAY C ONTAIN 9 ZERO BYTES (NO BOOT MESSAGE OR FILE NAME) AND THE ML CODE MUST THEN STA RT AT THE 10TH BYTE. ANY USE OF BOOT ME SSAGE AND/OR FILE NAME WILL FORCE THE ST ART OF THE ML CODE UPWARDS. AS THE COMP UTER'S BOOT BUFFER STARTS AT 2816 ($0B00 ), THE ACTUAL ENTRY POINT OF THE ML CODE CAN BE CALCULATED USING THE FOLLOWING F ORMULA:..2816+9+LENGTH OF BOOT MESSAGE+L ENGTH OF FILE NAME..THE TRANSFER PROCESS IS INITIATED BY A PROMPT FOR A FILE NAM E AND THE FILE WILL BE READ OFF THE DISK . YOU'LL THE BE ASKED FOR THE TARGET DI SK, THE DISK WHERE TO PUT THE BOOT SECTO R. YOU'LL BE WARNED IF THE TARGET DISK ALREADY HAS A VALID BOOT SECTOR OR IF TH E BOOT SECTOR IS OCCUPIED BY A FILE. TH EN, THE BOOT SECTOR IS SAVED TO DISK...C OPY BOOT SECTOR:.YOU MAY EASILY COPY A B OOT SECTOR FROM ONE DISK TO ANOTHER. PL EASE NOTE THAT ONLY TRACK 1, SECTOR 0 WI LL BE TRANSFERRED. MULTISECTOR BOOT ARE AS CANNOT BE TRANSFERRED BY THIS ROUTINE ...THE ORIGINAL BOOT SECTOR IS READ OFF THE DISK AND YOU'LL BE PROMPTED FOR THE TARGET DISK, THE DISK WHERE TO SAVE THE BOOT SECTOR. YOU'LL BE WARNED IF THE TA RGET DISK ALREADY HAS A VALID BOOT SECTO R OR IF THE BOOT SECTOR IS OCCUPIED BY A FILE. THEN, THE BOOT SECTOR IS SAVED T O DISK...KILL AUTOBOOT:.YOU MAY WANT TO REMOVE THE BOOT FEATURE FROM A DISK, AND THIS SELECTION WILL ENABLE YOU TO DO SO . ACTUALLY, THIS UTILITY ISN'T VERY RAD ICAL, THE "CBM" BOOT SECTOR IDENTIFIER I S CHANGED TO "KBM", AND THE BOOT SECTOR IS MARKED AS FREE IN THE BAM. IT MAY BE A GOOD IDEA TO TRANSFER THE BOOT SECTOR TO A FILE BEFORE KILLING IT...YOU'LL BE ASKED IF IT IS OK TO COMMENCE THE ACTIO N TO BE PERFORMED. THEN, THE BOOT SECTO R WILL BE DISABLED. YOU'LL BE NOTIFIED IF A BOOT SECTOR DON'T EXIST ON THE DISK , AND NO CHANGES WILL THEN BE MADE...UN- KILL AUTOBOOT:.IF YOU HAVE KILLED A BOOT SECTOR, EITHER DELIBERATELY OR BY ACCID ENT, IT MAY BE RE-ENABLED WITH THIS FEAT URE. SINCE THE KILL FEATURE MARKS THE B OOT SECTOR AS FREE IN THE BAM, THE BOOT SECTOR MIGHT EASILY BE OVERWRITTEN BY A FILE SAVED TO DISK. IT IS THEREFORE FEA SIBLE TO UN-KILL A BOOT SECTOR AS SOON A S POSSIBLE...THE DISK IS CHECKED TO SEE IF IT CONTAINS A RECOVERABLE BOOT SECTOR , AND YOU'RE ASKED IF IT IS OK TO PROCEE D. THE BOOT SECTOR IS THEN RESURRECTED. ..PROTECT SECTOR(S).FOR A BOOT SECTOR TO BE SAFE, IT MUST BE PROTECTED BY THE BL OCK AVAILABILITY MAP (BAM). ALTHOUGH TH E DOS COMMANDS VALIDATE WILL PROTECT THE BOOT SECTOR, THE BASIC COLLECT COMMAND AND OTHER WAYS OF VALIDATING THE DISK WI LL DE-PROTECT IT AGAIN. TO MAKE THINGS RIGHT, THE AUTOBOOT TOOL PROTECT COMMAND WILL RE-PROTECT THE BOOT SECTOR(S) WITH OUT VALIDATING THE WHOLE DISK. PLEASE N OTE THAT MULTISECTOR BOOT AREAS WILL BE PROTECTED BY THIS UTILITY..
