IDT: %100 guaranteed reboot

I have tested lots ( and I mean more than lots ) of v86, IDT, and everything else you can use to get BIOS int's in PMode code.

And I have a %100 guarante that it'll reboot my computer if I compile it! ( and I don't even change the sources! ).
John Fines work ( the only one ), but I need to compile it in DOS & Windows, when I like programming in Linux.

ANYONE who has a pre-compiled bin format file that does a BIOS int I would VERY much like to see if it's my computer.

Thank you,

Hm, do you make a BIOS interrupt while in Protected Mode? If yes, it's no surprise that your CPU reboots, because this is not possible...

Hi, if you can't get the v86 to work, you could try manually switching back to real mode with suitable selectors, execute the BIOS interrupt you are interested in and then switch back to Protected mode! This will enable you try out the ideas you have without getting distracted by implementing a v86 mode system,especially if you are rarely going to use v86 . ;D
