Suggestions for i386-PC mode

Open rdragonz opened this issue 4 years ago • 10 comments

I believe that porting all commands from the EFI mode to the i386-PC mode. This would allow all computers to use all the features available in this port.

"all commands"? that's impossible.

All commands that are not UEFI specific, sorry I made a mistake in the original post.

rdragonz avatar Dec 30 '19 10:12 rdragonz

Could you please list these commands?

a1ive avatar Dec 30 '19 10:12 a1ive

Specifically map and wimboot, these commands are the best features of this port.

I could port 'wimboot' to i386-pc. However we can't port 'map' to i386-pc. Instead, we need to completely rewrite this module, but I'm not good at assembly.

wimboot would be a good addition, considering there is already a BIOS version of it, but it has nowhere near the ease of use as the version in this fork of grub2. Regarding map, there is already a version of the map command in grub4dos. (See https://sourceforge.net/projects/grub4dos/files/GRUB4DOS/)

I'm not good at assembly languages (BIOS int13h call).

Doesn't loop work OK instead of map for most ISOs? I thought grub2 already had wimboot for i386 in your version as well as UEFI?

Loop does not work for raw isos such as FreeDOS, and no this build does not have wimboot in i386 mode currently

I don't understand? grubfm has wimboot support and I thought it was also in a1ive's grub2? See /boot/grub/open.lua image Also distro/windows.sh image

Does it matter that it is not built-in to the grub2 kernel?

Most people either use memdisk for DOS payloads, or call grub.exe (grub4dos executable). Can you give a specific example of a DOS ISO that works in grub4dos but does not work in grub2?
