Arkady,
Look at cli / sti - assembly opcodes
These opcodes enable and disable interrupts on a given CPU on
"all-or-none" basis, and this is not what the OP wants. Furthermore,
they affect only the given CPU, and the OP wants to disable IRQ for all
CPUs. Therefore, tricks with IF flag is of no help here - instead, you
have to do it via IOAPIC (on APIC HAL).
However, as Don properly pointed out, doing so is unwise, at least in
commercial-grade product that is meant to run of different computers
and HALs...
