-! well, that went ok, I hope. Now we have to reprogram the interrupts :-(
-! we put them right after the intel-reserved hardware interrupts, at
-! int 0x20-0x2F. There they won't mess up anything. Sadly IBM really
-! messed this up with the original PC, and they haven't been able to
-! rectify it afterwards. Thus the bios puts interrupts at 0x08-0x0f,
-! which is used for the internal hardware interrupts as well. We just
-! have to reprogram the 8259's, and it isn't fun.
+! well, that went ok, I hope. Now we mask all interrupts - the rest
+! is done in init_IRQ().
