Note in the illustration that the CPU and the terminator have marks (usually a notch or a gold mark on one corner) to help you identify the proper orientation and enable you to correctly install them. It is important that you match the marked corner of the CPU and terminator with the corresponding corner on the socket so as not to damage the CPU pins.

WARNING! If you are installing this motherboard into a 1U system,you must

use a specially designed heatsink qualified for critical environments. Failure to do so will cause the CPU to overheat and may damage both the CPU and the motherboard.

3.7.2 Assigning IRQs for Expansion Cards

Some expansion cards need an IRQ to operate. Generally , an IRQ must be exclusively assigned to one use. In a standard design, there are 16 IRQs available but most of them are already in use, leaving 6 IRQs free for expansion cards. If the motherboard has PCI audio onboard, an additional IRQ will be used. If the motherboard also has MIDI enabled, another IRQ will be used, leaving 4 IRQs free.

The following table lists the default IRQ assignments for standard PC devices. Use this table when configuring your system and for resolving IRQ conflicts.

ISA Interrupt (IRQ) Assignments

ISA INT Priority Standard Function

ISA 00 1 System Timer ISA 01 2 Keyboard Controller

ISA 02 N/A Programmable Interrupt ISA 03* 11 Communications Port (COM2) ISA 04* 12 Communications Port (COM1) ISA 05* 13 Sound Card (sometimes LPT2)

ISA 06 14 Floppy Disk Controller ISA 07* 15 Printer Port (LPT1)

ISA 08 3 System CMOS/Real Time Clock ISA 09* 4 ACPI Mode when used ISA 10* 5 IRQ Holder for PCI Steering ISA 11* 6 IRQ Holder for PCI Steering ISA 12* 7 PS/2 Compatible Mouse Port

3.8.2 Internal Connectors

WARNING! Some pins are used for connectors or power sources. These are

clearly distinguished from jumpers in the Motherboard Layout. Placing jumper caps over these connector pins will cause damage to your motherboard.

IMPORTANT: Ribbon cables should always be connected with the red stripe to

Pin 1 on the connectors. Pin 1 is usually on the side closest to the power connector on hard drives and CD-ROM drives, but may be on the opposite side on floppy disk drives. Check the connectors before installation because there may be exceptions. IDE ribbon cable must be less than 46 cm (18 in.), with the second drive connector no more than 15 cm (6 in.) from the first connector.

1) Floppy Disk Drive Connector (34-1 pin FLOPPY)

This connector supports the provided floppy drive ribbon cable. After connecting the single end to the board, connect the two plugs on the other end to the floppy drives. (Pin 5 is removed to prevent inserting in the wr ong orientation when

using ribbon cables with pin 5 plugged).

2) Primary/Secondary IDE Connectors (40-1 pin IDE1/IDE2)

These connectors support UltraDMA/33 IDE hard disks. Use IDE ribbon cables to connect the master and slave devices to these connectors. If you install two hard disks, you must configure the second drive as a slave device by setting its jumper accordingly . Refer to the hard disk documentation for the jumper settings. BIOS supports specific device bootup (see 4.6. Boot Menu).

NOTE: Pin 20 on each IDE connector is removed to match the covered hole on the UltraDMA cable connector . This prevents incorrect orientation when you connect the cables.

TIP: You may configure two hard disks to be both Masters with two ribbon cables – one for the primary IDE connector and another for the secondary IDE connector.
