There is emulation code for the PIC (interrupt controller) and PIT (timer) + various other stuff. The intcall86() filters out and handles INT 10h/13h/etc but everything else is emulated "for real": ip/cs/flags are pushed, new cs:ip set, etc. There is an 8KB BIOS of some sort defined as a big array which should handle boot and hardware interrupts. > Probably many more subtle bugs with the flags as well. Sure. And lots of subtle bugs in general. Which is fine for someone's personal fun side project.
