chainload grub4dos from grub2 to boot cdrom/dvr?

Been doing some research, and found out that grub4dos will
boot a cdrom/dvr.

So how does one chainload the grub4dos from grub2?

Would you give me an example that shows how to
do boot a cdrom/dvr indirectly from grub2.

I believe this should solve your problem: https://ubuntuforums.org/showthread.php?t=1668939
What it does is keep grub2, places grub4dos and then creates a menu entry to boot grub4dos.

Will grub4dos still work on modern computers?

Grub4dos Is a 16 bit program, is it not?

If I am right, then modern bios don't support 16 bit programs.

Unless you can use QEMU emulator to use grub4dos.

Grub4dos works just fine on my notebook before I changed to grub2. In fact it works just fine on all 64bit computers that I know of.

I had a similar question for reverse, i.e., I want to boot Xenial and later splash screens from G4D: viewtopic.php?p=41519#p41519
