China DOS Union

Which friend can send me a reboot command, thank you!

Is RESTART a DOS command to restart the machine?

You can create one with DEBUG.

Which codes do you not understand? Can you give some pointers?

Why is there no -g=100?

Is there a direct restart that can skip the power-on self-test, like the restart in DiskGen? How is that done? It's very fast!

Thanks bushrestart, the Win98 boot disk (virtual disk) has it. JonePeng's method is more complicated.

I still suggest you find materials to understand JonePeng's program, which is good for you. I can explain: (HEX is used in DEBUG)
MOV AX,40
MOV DS,AX
MOV AX,1234
MOV ,AX
;These few lines write the word content at memory 0040:0072H as 1234H,
;This is a flag bit, prompting the BIOS to skip the memory self-test when restarting (warm boot)
JMP FFFF:0000
;This makes the CPU jump to the BIOS startup program entry, starting initialization, restarting.
When the power is just turned on, the program at this address will be automatically found by the CPU to start. The following RCX 10 is to set the length to 16 bytes for the W (write) instruction,
N REBOOT.COM is used to set the file name, so that a COM executable program is made. If you still don't understand, just read the book by yourself.

Here is the statement from sunbinjin on 2004-8-27 18:27:01:

I've also seen this kind of super - fast boot. I've checked relevant materials. As long as you simply call DOS interrupts 19H and 20H, you can achieve super - fast warm boot. You can do it with DEBUG by typing a few lines:
a100
int 19
int 20
rcx
4
n fastboot.com
w
q
This FastBoot.com program is only 4 bytes! When you run it, you can skip the system POST and directly boot the operating system. After repeated tests, I found that it has a shortcoming. Once EMM386 is loaded in Config.sys, this FastBoot will perform a normal warm boot. Unless EMM386 is disabled, FastBoot will be FAST.

Please clarify the specific content you want to translate. You just provided a sentence "给个fastboot.com下载吧？？", which is in Chinese. The translation is "Can you give a download link for fastboot.com??"

This FastBoot.com is a small program I made by myself, and it's not available for download online. It's also very simple to make with DEBUG, but considering that some friends don't know how to use DEBUG, I've uploaded this FastBoot.com. Open the attachment

good,thank you

DEBUG
a100
int 19
int 20
rcx//What does this mean?
4//>??????
n fastboot.com
w
q

Take a close look at the instructions in floor 8. Still, you need to study carefully by yourself.

Oh, thanks. The key is that it didn't work on my lousy machine, so I asked. Why did my machine just make a beep from the floppy drive and then nothing happened, it died. Had to reset.
