I am fortunate to have found this website and hope to get help. I want to find a small program that can realize the timed shutdown of the ATX power supply in the DOS environment. Please help, teachers.

Shutting down under DOS is okay, but for timing the shutdown, I don't know if there is such a software. I haven't seen such a software.

Since it's not possible to directly achieve the timed shutdown of an ATX power supply, can we change our approach—indirectly achieving the timed shutdown of an ATX power supply. That is, Program A—can do timing to call some other programs; Shutdown program—achieves the shutdown of the ATX power supply. First run "Program A", and let it call "Shutdown program" at a certain moment. I would like to ask, is there such a "timed program caller"?

It seems that comrades raised such a question a long time ago. Is there a solution now?

I only know there is an AT command for timing, but it doesn't run under DOS

Since you know it's not under DOS, then what's the point of your reply like this?

Sure, first you can judge when to shut down by reading the time. Reading the time can be done by reading the CMOS value. As for shutting down under DOS, you can call the BIOS or some shutdown programs.

Only those supporting APM have the shutdown function call of INT 15H. MOV AX,5300H XOR BX,BX INT 15H JNB NEXT JMP NOAPM NEXT:MOV AX,5301H XOR BX,BX INT 15H MOV AX,530EH XOR BX,BX MOV CX,101H INT 15H MOV AX,530FH MOV BX,1 MOV CX,BX INT 15H MOV AX,5308H MOV BX,1 MOV CX,BX INT 15H MOV AX,5307H MOV BX,1 MOV CX,3 INT 15H NOAPM: ;Shutdown not supporting APM What is rather strange is that usually those supporting APM will use it. MOV AL,0BH OUT 0B2H,AL HLT For those only supporting ACPI shutdown, you can try the following program. Since it uses specific I/O ports, the compatibility is not very good. MOV AL,0EH MOV DX,0CF9H OUT DX,AL HLT As for the timing issue, improve it yourself [ Last edited by netwinxp on 2008-12-23 at 15:40 ]
