Unprotect BLAST Rev 7.2.1 (MS-DOS) Your PC or compatible must be running MS-DOS 2.1 or later and have at least 256k to run FIXBLAST.BAT. You must have the following files on one diskette (or in one directory) to unprotect BLAST: BLAST.EXE -- copy from your original BLAST diskette FIXBLAST.BAT FIXBLAST.IN1 FIXBLAST.IN2 DEBUG.COM -- copy from your MS-DOS system diskette (You may set a PATH to DEBUG instead of copying) Type FIXBLAST from your MS-DOS system prompt. FIXBLAST.BAT uses DEBUG with input from FIXBLAST.IN1 and FIXBLAST.IN2 to unprotect BLAST.EXE.
