Page 11: External Connectors
To simplify this process the motherboard has complied with the Plug and Play (PNP) specification which was developed to allow automatic system configuration whenever a PNP- compliant card is added to the system. For PNP cards, IRQs are assigned automatically from those available. - Page 12 The PS/2 Keyboard is a 6-pin miniature DIN connector. It is for a standard PS/2 style keyboard. May also be known as a 101 enhanced keyboard. The PS/2 Mouse connector is a similar 6-pin, miniature DIN connector. PS/2 Mouse PS/2 Keyboard 3.

Page 17: Award Bios Setup
AWARD BIOS SETUP Award's ROM BIOS provides a built-in Setup program which allows user modify the basic system configuration and hardware parameters. The modified data will be stored in a battery- backed CMOS RAM so data will be retained even when the power is turned off. In general, the information saved in the CMOS RAM stay unchanged unless here is configuration change in the system, such as hard drive replacement or new equipment is installed. -
