Resume by Alarm

When enabled, the user is allowed to set the Date and Time.
Reload Global Timer Events
The HDD, FDD, COM, LPT Ports, and PCI PIRQ are I/O events that can
prevent the system from entering a power saving mode or can awaken
the system from such a mode. When an I/O device wants to gain the
attention of the operating system, it signals this by causing an IRQ to
occur. When the operating system is ready to respond to the request, it
interrupts itself and performs the service.
Notes:
HPET (High Precision Event Timer) is meant to supplement and replace
the 8254 Programmable Interval Timer (PIT) and the Real-time clock's
(RTC) periodic interrupt function. Compared to these older timer
circuits, the HPET has higher frequency (at least 10 MHz) and wider
64-bit counters (although they can be driven in 32-bit mode).
