DMBB.EXE: two programs in one. First a super sys-info. More than 250 tests : date, bios, dos, cpu (NEC V20, V30, Intel 8088, 8086, 80188, 80186, 80286, 80386, 80486, SX ou DX...), coprocessor, current and boot drive, floppies, printers, memory (conv, extented, EMS, XMS), TSR, SFT, ... Second an utility for batch programs. All the results of these 250 tests can be return onto ERRORLEVEL, and tested by the IF command of batch files. You can build very efficient batch programs.
