Hi Everyone, 
 I'm having some trouble getting an IDT loaded into the processor.
I though 
that the lidt instruction took a pointer (e.g. 32-bits), but dmd only
compiles 
my code if I pass it a 64-bit argument. What is this argument supposed
to be? 
 
 Thanks a lot.

See the example at: http://osdev.neopages.net/tutorials/interrupts.3.php
(Scroll down to the bottom). Here, NASM takes a pointer to a 6-byte
structure for its lidt instruction. I don't see why D asks for an 8 byte
parameter.

I'll check it out. In the meantime, you can just use db's to put in the
right bits for the instruction you want.

 Any updates on this?  If not, how do db's using D inline assembler?
