DPROTECT.ARC - the old DPROTECT.LBR (circa 1985).
Protects all hard disks and all or a single floppy drive
against writes.
Because of a report that a virus-infected version of
DPROTECT.COM was floating around, I disassembled this
program to be sure.
Files:
DPROTECT.COM Original program
DPROTECT.DOC Original program documentation,
with my comments appended.
READ.ME Original note on net use.
DPROTECT.ASM Documented disassembly source code.
DPROTECT.SEQ ASMGEN instruction file for disassembly.
DPROTEC1.COM Compilation of the tweaked disassembly.
