After qnx4 has been loaded by bios on x86 platform, when operating
low-level hardware,does qnx4 call bios interrupt? do bios’s System
Management Mode and VGA function still work?
thanks

I don’t know what you mean by VGA function, but system management mode

System Managment Mode is an evil concept. It can completely negate a systems
real time capabilities.
