2-5-3 Interrupt Request Table For This Motherboard Interrupt request are shared as shown the table below: Slot 1 Slot 2 Slot 3 Onboard USB 1 Onboard USB 2 AC97/MC97 INT A √ INT B INT C INT D INT E INT F INT G INT H √ √ √ √ √ IMPORTANT! If using PCI cards on shared slots, make sure that the drivers support “Shared IRQ” or that the cards don’t need IRQ assignments. Conflicts will arise between the two PCI groups that will make the system unstable or cards inoperable.
** We recommend that you use an ATX 12V Specification 2.0-compliant power supply unit (PSU) with a minimum of 350W power rating. This type has 24-pin and 4-pin power plugs. ** If you intend to use a PSU with 20-pin and 4-pin power plugs, make sure that the 20-pin power plug can provide at least 15A on +12V and the power supply unit has a minimum power rating of 350W. The system may become unstable or may not boot up if the power is inadequate.
(6) Parallel Port Connector (25-pin female): PARALLEL Parallel Port connector is a 25-pin D-Subminiature Receptacle connector. The Onboard Parallel Port can be disabled through the BIOS SETUP. Please refer to Chapter 3 “INTEGRATED PERIPHERALS SETUP” section for more detail information.
IDE2 IDE1 Pin 1 Primary IDE Connector (11) Secondary IDE Connector (40-pin block): IDE2 This connector connects to the next set of Master and Slave hard disks. Follow the same procedure described for the primary IDE connector. You may also configure two hard disks to be both Masters using one ribbon cable on the primary IDE connector and another ribbon cable on the secondary IDE connector. IDE2 IDE1 Pin 1 Secondary IDE Connector • • Two hard disks can be connected to each connector.

Chapter 3 Introducing BIOS The BIOS is a program located on a Flash Memory on the motherboard. This program is a bridge between motherboard and operating system. When you start the computer, the BIOS program gain control. The BIOS first operates an auto-diagnostic test called POST (power on self test) for all the necessary hardware, it detects the entire hardware device and configures the parameters of the hardware synchronization.

Time The time format is . Primary Master/Primary Slave Secondary Master/Secondary Slave Press PgUp/<+> or PgDn/<–> to select Manual, None, Auto type. Note that the specifications of your drive must match with the drive table. The hard disk will not work properly if you enter improper information for this category. If your hard disk drive type is not matched or listed, you can use Manual to define your own drive type manually.
Virus Warning Allows you to choose the VIRUS Warning feature for IDE Hard Disk boot sector protection. If this function is enabled and someone attempt to write data into this area, BIOS will show a warning message on screen and alarm beep. Disabled (default) No warning message to appear when anything attempts to access the boot sector or hard disk partition table.
Typematic Delay (Msec) Sets the delay time after the key is held down before is begins to repeat the keystroke. The settings are 250, 500, 750, and 1000. Security Option This category allows you to limit access to the system and Setup, or just to Setup. The system will not boot and access to Setup will be denied if the System correct password is not entered at the prompt. Setup (default) The system will boot, but access to Setup will be denied if the correct password is not entered prompt.
