PM Timers This section controls the time-out settings for the Power Management scheme. The fields included in this section are "HDD Power Down", which places the hard disk into its lowest power consumption mode, and the "Suspend Mode" which suspends the CPU. The system automatically "wakes up" from any power saving mode when there is system activity such as when a key is pressed from the keyboard, or when there is activity detected from the enabled IRQ channels. HDD Power Down (Disable) Shuts down any IDE hard disk drives in the system after a period of inactivity. This time period is user-configurable to 1­15 Min or Disable. This feature does not affect SCSI hard drives. Suspend Mode (Disable) Sets the period of time after which each of these modes activate: 30 sec, 1 Min, 2 Min, 4 Min, 8 Min, 20 Min, 30 Min, 40 Min, 1 Hour, and Disable. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Power Up Control This section determines the ways the system can be controlled when it is started or restarted, when modem activity is detected, or when power to the computer is interrupted and reapplied. The Soft-Off mode refers to powering off the system through a momentary button switch (ATX switch) or through the software as opposed to disconnecting the AC power by way of a rocker switch or other means. PWR Button < 4 Secs (Soft Off) When set to Soft Off, the ATX switch can be used as a normal system power-off button when pressed for less than 4 seconds. Suspend allows the button to have a dual function where pressing less than 4 seconds will place the system in sleep mode. Regardless of the setting, holding the ATX switch for more than 4 seconds will power off the system. 4. BIOS Power Management 56 ASUS P2B-N User's Manual 4. BIOS SETUP PWR Up On Modem Act (Enabled) This allows either settings of Enabled or Disabled for powering up the computer (turns the ATX power supply on) when the modem receives a call while the computer is Soft-off. NOTE: The computer cannot receive or transmit data until the computer and applications are fully running, thus connection cannot be made on the first try. Turning an external modem off and then back on while the computer is off causes an initialization string that will also cause the system to power on. AC PWR Loss Restart (Disabled) This allows you to set whether you want your system to boot up after the power has been interrupted. Disabled leaves your system off after reapplying power and Enabled boots up your system after reapplying power. Power Up By Keyboard (Disabled) Set this field to Enabled if you wish to use your PS2 keyboard (by pressing the spacebar) to power up your computer. This feature requires an ATX power supply that can supply at least 300mA on the +5VSB lead. [. . . ] APPENDIX MMX A set of 57 new instructions based on a technique called Single Instruction, Multiple Data (SIMD), which is built into the new Intel Pentium PP/MT (P55C) and Pentium II (Klamath) CPU as well as other x86-compatible microprocessors. The MMX instructions are designed to accelerate multimedia and communications applications, such as 3D video, 3D sound, video conference. PCI Bus (Peripheral Component Interconnect Local Bus) PCI bus is a specification that defines a 32-bit data bus interface. PCI is a standard widely used by expansion card manufacturers. [. . . ]
