Hi,
here's some interesting article where Linus comments on ongoing CPU changes
https://www.zdnet.com/article/linus-torvalds-on-ho...-changing-how-processor-interrupts-are-handled/
I'm not familiar with details and never programmed IDT so I'm just asking if it have some impact on our legacy DOS (and for someone Windows) systems that use pmode like JEMM, etc... If I understand well intel should have some control bit to switch between new and legacy behavior so there should not be problem until they remove that legacy mode...

DOS gives me freedom to unlimited HW access.
