Bruce: If what you say is true, the only place I can be sure to save time (this is on a 486DX4/100) is at the ICU by setting those AUTO_EOI flags. But how safe are these? I was getting missed IDE completion interrupts with a kernel that had AUTO_EOI_1 on, but don't know if that was the only source of the problem. (I've changed a LOT of options in more recent kernels.) --Brett
