China DOS Union

It's done quite well.. My BIOS space is just a bit small!

The method is good, but the problem is there's no floppy drive.

Floppy drives are a big problem now. A few years ago, USB floppy drives were still okay. I don't know how they are now.

Manufacturers of COMS chips should take a look at this post. Just add a DOS to all BIOS. At least I like DOS.

I have experimented according to your method. All ROMOS.BIN has been added. After flashing it in with @BIOS, there is no reaction at all, and no prompt message can be seen. Later, I experimented with ROMOS16K.BIN, still no good. My English is not good. I was afraid of not having enough space, so I also removed a PXE module. Now there should still be more than 90K left. Please help me see where I made a mistake.

It seems that the original poster is a DIY expert. I haven't dared to flash the BIOS yet. I'm behind.

Dude, you're really creative!

PXE should be the network boot module, it's okay to remove it.

Is your BIN file okay??
Have you tested it??

Thanks for your reply.

The problems are as follows: 1: I'm not very sure that the file is okay. All are the latest BIOS files downloaded from the website. And after flashing it in, it can start normally, but I can't see the DOS prompt information. 2: When flashing, I found that when the space is only more than 80KB, the prompt information of the flashed - in file is 93.3% (not sure). And after I removed several modules, the space is 120KB. When flashing the file, the prompt is 53.5%. I don't know what's different. (Tried many times) 3: I saw in your post that for integrated graphics card, the VGA module can be removed. As a result, after I removed it, there was a problem. 4: Finally, I made a fatal mistake. I was in a hurry to go to work last time, and as a result, I flashed the wrong file. After discharging, it seems that the computer can start normally. I estimate that I can't enter XP because the VGA module is gone. I can't see what the computer reflects when it starts. (The file I flashed wrong belongs to the same series as my original BIOS file. Maybe because of this, it can start normally to the minimum extent)

Note: I don't have a floppy drive. I took it to repair and it will take several days to get it well. The problem is not big, but it's very troublesome.

Do you have an on-board graphics card on your computer??

If so, it is not ruled out that the graphics card is VGA, so it is deleted. Of course, there is a problem,

Generally, the VGA module is deleted because there is an external non-VGA graphics card
