China DOS Union

Dear masters:

Recently I tried to boot with DOS, then opened a ramdisk, then put the image file into the ramdisk, and finally used grub to load this image, but it always said it couldn't find the file.

I'm a novice. I searched the articles and didn't see similar ones or I missed it. Please ask you masters if this is feasible?

In the readme_grub4dos.txt document of grub4dos, you can find information on this. The hmload command by John Cobb might be useful for you. You can also go to

http://sysdocs.stu.qmul.ac.uk/sysdocs/Comment/GrubForDOS/

to see information on this.

Note that the RAMdisk established directly with DOS won't work. Because after entering grub4dos, DOS disappears, so the DOS RAMdisk device can't be used either.

Therefore, you need to use hmload to place the image file directly in extended memory, so that after entering grub, there is a way to access this image file in extended memory.

This is a more advanced usage. You need to be prepared to study, experiment, and explore by yourself to succeed.

I tried hmload before, it can let me use the mirror in grub4dos.

It seems I need to work harder to try.

Thanks for not clicking, very grateful.

I tried this before. Before entering DOS, use memdisk to create a ramdisk virtual hard disk first, then enter DOS and copy the image file to this virtual hard disk. Then use grub.exe to enter grub, and in grub, you can access this memdisk and successfully load this image.
