Virtual 86 Mode

[TheUbu]

Hey,

I set up a bios call mech using v86 however some things work such as vesa get mode info however if i try to set a video mode it fails horribly and I cant get information out of the system to see whats going on. In my v86 gpf handler i handle most things pushf popf int is there maybe a really good tutorial out there or am I missing something more then the basics?

Tim,

Yes most bios calls work I'm having issues with specific ones such as setting a video mode it starts to set mode you lose video signal and it sits there.
