Page 13
III. INSTALLATION WARNING: Some pins are used for connectors or power sources. These are clearly separated from jumpers in "Map of the Motherboard" on page 4. Placing jumper caps over these will cause damage to your motherboard. WARNING: Computer motheboards and components contain very delicate Integrated Circuit (IC) chips.
III. INSTALLATION Jumper Settings 1. Onboard Multi-I/O Selection (JP4) You can selectively disable each onboard Multi-I/O item (floppy, serial, parallel, and IrDA) through BIOS (see page 35) or disable all Multi-I/O items at once with the following jumper in order to use your own Multi- I/O card.
Page 15
This jumper sets the total amount of L2 cache that is present. If you have two cache chips onboard (see "Map of Motherboard" for locations), then you have either 256KB or 512KB. An "ASUS" or "COAST" cache module can be used to upgrade the 256KB version to 512KB. If there is no onboard cache, you must install a cache module of either 256KB or 512KB.
Page 16
III. INSTALLATION 5. CPU External (BUS) Frequency Selection (JP26, 27, 28) These jumpers tells the clock generator what frequency to send to the CPU. These allow the selection of the CPU’s External frequency (or BUS Clock). The BUS Clock times the BUS Ratio equals the CPU's Internal frequency (the advertised CPU speed).
Page 17
III. INSTALLATION 7. PS/2 Mouse on IRQ12 Setting (JP7) This jumper enables or disables the onboard PS/2 mouse lead connector. When Enabled, the port becomes active and uses IRQ12. When Disabled, IRQ12 will be freed for use by a PCI or ISA expansion card. See Page 19 for the "PS/2 Mouse connector."...
III. INSTALLATION 2. System Memory (DRAM) This motherboard supports four 72-pin SIMMs of 4MB, 8MB, 16MB, or 32MB to form a memory size between 8MB to 128MB. For BUS frequen- cies of 50MHz or 60MHz, you can use either 60ns or 70ns modules. For BUS frequencies of 66MHz, you must use 60ns modules.
III. INSTALLATION DRAM Memory Installation Procedures: 1. The SIMM memory modules will only fit in one orientation as shown because of a "Plastic Safety Tab" on one end of the SIMM slots which requires the "Notched End" of the SIMM memory modules. Notched End 72 Pin SIMM DRAM Slots &...
COAST 2.1 COAST 3.0 NOTE: Motherboard PCB 1.0 can only use ASUS CM1 Rev. 1.6 to up- grade the 256KB version to 512KB. 0KB version can use all modules for upgrade to 256KB or 512KB except the ASUS CM1 Rev. 1.6.
III. INSTALLATION 3. Central Processing Unit (CPU) The motherboard provides a 321-pin ZIF Socket 7 that is backwards com- patible with ZIF Socket 5 processors. The CPU that came with the mother- board should have a fan attached to it to prevent overheating. If this is not the case then purchase a fan before you turn on your system.
III. INSTALLATION 4. Expansion Cards First read your expansion card documentation on any hardware and soft- ware settings that may be required to setup your specific card. NOTE: PCI Slot 4 has a MediaBus extension 2.0 (see page 18) which allows the installation of a PCI card or a MediaBus card (optional multi- functional card) but not both.
III. INSTALLATION Diagnostic (MSD.EXE) utility included in the Windows directory to see a map of your used and free IRQs. For Windows 95 users, the "Control Panel" icon in "My Computer," contains a "System" icon which gives you a "De- vice Manager"...
III. INSTALLATION ASUS MediaBus Card MediaBus allows a cost-efficient solution to a complete multimedia sys- tem. The advantages of using one add-on card is to reduce the slot require- ments and compatibility problems in order to maximize the Plug and Play advantages.
III. INSTALLATION 5. External Connectors IMPORTANT: Ribbon cables should always be connected with the red stripe on the Pin 1 side of the connector. The four corners of the con- nectors are labeled on the motherboard. Pin 1 is the side closest to the power connector on hard drives and floppy drives.

VI. PCI-SC200 SCSI Card NCR SCSI BIOS and Drivers Aside from the system BIOS, the Flash memory chip on the motherboard also contains the NCR SCSI BIOS. This SCSI BIOS works in conjunction with the optional PCI-SC200 SCSI controller card to provide a complete PCI Fast SCSI-2 interface.
VI. PCI-SC200 SCSI Card The PCI-SC200 SCSI Interface Card Your motherboard may have come with an optional SCSI (Small Computer System Interface) controller card, the PCI-SC200. The card is also avail- able separately. This card works with the SCSI BIOS on the motherboard. Together, they provide a complete PCI Fast SCSI-2 interface.
VI. PCI-SC200 SCSI Card Setting the INT Assignment You must use PCI INT A setting in order to properly assign the card's inter- rupt. On the PCI-SC200, you assign the INT by setting jumper JP1 or JP2. The default setting for the card already is INT A, so you do not need to change the setting to use the PCI-SC200 with this motherboard.
VI. PCI-SC200 SCSI Card Decide whether or not you need to terminate the PCI-SC200 based on its position in the SCSI chain. Only the devices at each end of the chain need to be terminated. If you have only internal or only external devices connected to the PCI-SC200, then you must terminate the PCI-SC200.
