Chapter 3 BIOS Configuration
Suspend Mode
When enabled, and after the set time of system inactivity, all devices except the CPU will be shut off.
PM Events
The VGA, LPT & COM, HDD & FDD, DMA/master, PWR-ON by Modem/LAN, RTC Alarm Resume, and Primary INTR sections are I/O events which 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. When set to ON, activity will neither prevent the system from going into a power management mode nor awaken it. The IRQ section sets the wake-up call of the system. If activity is detected from any enabled IRQ channels in the left-hand group, the system wakes up from Suspend Mode.
