China DOS Union

Novice question

Downloaded GNU GRUB Greater China Localized Version 0.95

Want to make a maintenance system 2.88 standard floppy image is too small
Downloaded WinImage 8.0 to generate a 6M floppy image that can't boot.
Added C/H/S parameters can't boot
Ask for advice from all you big guys

It is suggested to download grub4dos and refer to the official usage instructions.

Adding the CHS parameter should allow it to start. I guess the parameter was added incorrectly. Hehe.

Used the built-in MAP
Still cannot boot

title Run Floppy Image
map (hd0,0)/boot/grub/win99.img　(fd0)
map --hook
chainloader (fd0)+1
rootnoverify (fd0)

Of course, first of all, make sure your img is bootable. Hehe. The map method has no limit on the size of the floppy image, but it requires continuous storage.

The img is bootable. I put the file into the standard 2.88 one and it can boot. But when it comes to a large floppy disk image, it can't boot. Which big shot can help analyze it? Also, what should be noted or what are the skills in making floppy disk images?

It has been solved. It was because the floppy disk image I made was not working. I found a 20-size floppy disk image in the GRUB4DOS area that can successfully boot the floppy disk image.

And I am very grateful to lianjiang2004 for the enthusiastic help.

Is there anyone who knows how to make a floppy disk image? (The self-made disk image is made with WINIMAGE 8.0) Give a detailed tutorial or explanation

There is no problem with using WinImage. I made a 7-8MB img just like this, and it boots without issues.
