INT 16 - PC-Cache v6+ - FLUSH CACHE AND DISABLE DELAYED WRITES AX = FFA5h CX = CCCCh Return: AX = ??? (apparently either 0000h or sectors_in_cache - 5) Note: delayed writes are automatically disabled on EXECing (see INT 21/AH=4Bh) a program named either WIN.CO? or DV.E??; however, delayed writes are not automatically reenabled upon the program's termination in v6.
