AOpen i865 Family Motherboards

Serial ATA Supported

The traditional parallel ATA specification has defined the standard storage interface for PCs with its original speed of just 3 Mbytes/second since the protocol was introduced in the 1980s. And the latest generation of the interface, Ultra ATA-133,has been developed further with a burst data transfer rate of 133 Mbytes/second. However, while ATA has enjoyed an illustrious track record, the specification is now showing its age and imposes some serious design issues on today’s developers, including a5-voltsignaling requirement, high pin count, and serious cabling headaches.

The Serial ATA specification is designed to overcome these design limitations while enabling the storage interface to scale with the growing media rate demands of PC platforms. Serial ATA is to replace parallel ATA with the compatibility with existing operating systems and drivers, adding performance headroom for years to come. It reduces voltage and pins count requirements and can be implemented with thin and easy to route cables.

Connecting Serial ATA Disk

You will find the claret serial ATA connectors in motherboard easily. To connect a Serial ATA disk, you have to have a 7-pinserial ATA cable. Connect two ends of the serial ATA cable to the serial ATA header on the motherboard and the disk. Like every other traditional disk, you also have to connect a power cable. Please be noted that it is a jumper free implement; you don’t need to set jumpers to define a master or slave disk. When serial ATA hard disks are installed on serial ATA ports, the one connected on Port 0(SATA 1) will be set as the first boot device automatically. Please be noted that it doesn’t supportHot-Plugin function.

Adjusting Your Hard Disk

Except its original 2 sets of parallel IDE, this motherboard does come with the support for the latest Serial ATA hard disk. If you are unable to find your newly installed Serial ATA hard disks on your operating system after you have had installed them on, the problem mainly lies in the BIOS setting. You may simply adjust BIOS settings to have them work properly.

After having properly installed your hard disks, you may directly get into the BIOS setting screen for adjustment. You may simply press “Integrated Peripherals Æ On-ChipIDE DeviceÆ On-ChipSerial ATA” to choose your preferable mode. If you have no intention of changing its setting, the default would be Auto.

AOpen i865 Family Motherboards OOnnlliinnee MMaannuuaall

If you intend to change the default setting, simply press Enter for a list of selection:

1.Disabled: You may choose this item if you’re sure that only traditional IDE hard disks had been installed on your system. Disabling this item may also cancel the detection to Serial ATA hard disk during POST, which theoretically, could speed up yourboot-uptiming for a little bit; however, please remember tore-adjustthe settings here if you intend to use Serial ATA hard disk later.

2.Auto: This is the default setting upon receipt of the motherboard. Basically, if your system functions properly, it’s not necessary to change it. The system will automatically recognize the first hard disk on IDE1 as the first boot device.

Note: Please be informed that when you are using Windows98/ME with six hard disks fully installed, Auto mode is not able to function properly, it’s just because Windows98/Me is not able to energize Enhanced Mode to detect all hard disks.

3.Combined Mode: If you have had installed traditional IDE hard disks and Serial ATA hard disks at the same time, then you may choose this Combined Mode. Under this mode, you may randomly choose either IDE hard disks or Serial ATA had disk as your first boot device. But please be aware that Serial ATA will exist with IDE in a mapping way, which also means it will occupy one of the IDE Channel and left you with one IDE Channel only.

4.Enhanced Mode: If you are using the latest operating system (say, Windows XP, Windows.NET Server), it is highly recommended to select Enhanced Mode. The system would be able to detect all six devices (traditional IDE x4, Serial ATA x 2) completely and functions perfectly under this mode. But please be noted that it is defaulted with using traditional IDE as the first boot device.

Note: From our practical lab tests, we found no obvious problem or mistakes happened under Windows2000 operating system, but, however, it is not within the regulation recommended by Intel.

5.SATA Only: You may select this SATA Only mode if you have had installed Serial ATA hard disks only. It also allows you to select booting sequence from Port0 (SerialATA1) or Port1 (SerialATA2).

Front Panel Connector

The pins of Front Panel Connector are painted in different colors with their respective functions. Please attach the power LED, speaker, power and reset switch connectors to the corresponding pins matched in same colors. If you enable “Suspend Mode” item in BIOS Setup, the ACPI & Power LED will keep flashing or high light while the system is in suspend mode.

Locate the power switch cable from your ATX housing. It is 2-pinfemale connector from the housing front panel. Plug this connector to thesoft-powerswitch connector markedSPWR.

AGP (Accelerated Graphic Port) 8X Expansionn SSlloott

AOpen i865 Family Motherboards provides an AGP 8X slot, a sky blue slot which has the latest AGP specification in motherboard. The AGP 8X is a bus interface targeted forhigh-performance3D graphic. AGP uses both rising and falling edge of the 66MHz clock, for 4X AGP, the data transfer rate is 66MHz x 4bytes x 4 = 1056MB/s. AGP is now moving to AGP 8X mode, which is 66MHz x 4bytes x 8 =2.1GB/s. You can also adjust AGP voltage in BIOS within a range from 1.5V to 1.6V. For AX4SG series, this AGP slot could automatically become an AGP slot or a Multiplexed Intel DVO Output depending on what kind of cards inserted, like AGP, or ADD (AGP Digital Display) cards. With ADD card cabled to this slot, Multiplexed Intel DVO output could providehigh-speeddigital connection for digital displays orTV-OUTfunctionality.

Warning: It is strongly recommended not to adjust voltage/clock of AGP/PCI when connecting any SATA service. It is because when the voltage/clock for AGP/PCI is adjusted, the clock for SATA couldn’t keep 100MHz, and the system will be unstable.

Warning: It is strongly recommended not to install a 3.3V AGP card, which is not supported by Intel 865G / 865PE / 848P chipset.

AGP Protection Technology and AGP LED

With the outstanding R&D ability of AOpen and its specially developed circuit, this motherboard implements a blend new technology to protect your motherboard from being damaged by over voltage of AGP card. When AGP Protection Technology is implemented, this motherboard will automatically detect the voltage of AGP card and prevent your chipsets from being burnt out. Please note that if you install a AGP card with 3.3V, which is not supported by Intel 865 chipset, the AGP LED on the motherboard will light up to warn you the possible damage of the exceeding voltage. You may contact your AGP card vendor for further support.

Support 10/100/1000 Mbps LAN onboard

On the strength of Gigabit LAN controller (-ULseries) or Realtek 10/100Mbps LAN controller(-UNseries) on board, this motherboard provides 10/100 Mbps (for Gigabit LAN, it is 10/100/1000 Mbps) Ethernet for office and home use. To–Useries motherboards, they do not support LAN onboard. The Ethernet RJ45 connector is located on top of USB connectors. The right hand side LED indicates link mode, it lights in orange whenever linking to network. The left hand side LED indicates the transfer mode and it lights in green when data is transferring in 100Mbps (never lights while in 10Mbps), but lights in orange when transferring in Gigabit’s mode. To enable or disable this function, you may simply adjust it through BIOS. To enable LAN wakeup function, you have to set the “Wake on PCI Card” enable in the BIOS “Power Management Setup” section.

Support USB 2.0 Ports

This motherboard provides eight USB 2.0 ports to connect USB devices such as mouse, keyboard, modem, printer, etc. There are two USB headers on the board for you to connect two USB devices and four other ports on the back panel. You can use proper cables to connect USB devices from back panel or connect the front USB connector to the front panel of chassis.

Compared to traditional USB 1.0/1.1 with the speed of 12Mbps, USB 2.0 has a fancy speed up to 480Mbps that is 40 times faster than the traditional one. Except for the speed increase, USB 2.0 supports old USB 1.0/1.1 software and peripherals, offering impressive and even better compatibility to customers. On this motherboard, all eight ports support USB 2.0 function.
