[. . . ] However, it depends on CPU/chipset design. CPU L2 Cache ECC Checking: This item allows you enable/disable CPU L2 Cache ECC checking. The choice: Enabled, Disabled. Enabled Quick Power On Self Test: This category speeds up Power On Self Test (POST) after you power up the computer. If it is set to Enable, BIOS will shorten or skip some check items during POST. Enabled Enable quick POST Disabled Normal POST First/Second/Third/Other Boot Device: The BIOS attempts to load the operating system from the devices in the sequence selected in these items. The Choice: Floppy, LS/ZIP, HDD, SCSI, and CDROM. Other Boot Device: If this option is enable the Bios will attempt to load operating system from other boot device that is available if the other fails. Swap Floppy Drive: If the system has two floppy drives, you can swap the logical drive name assignments. The choice: Enabled/Disabled. Boot Up Floppy Seek: Seeks disk drives during boot up. Disabling speeds boot up. The choice: Enabled/Disabled. Boot Up NumLock Status: Select power on state for NumLock. The choice: Enabled/Disabled. Gate A20 Option: Select if chipset or keyboard controller should control GateA20. Normal A pin in the keyboard controller controls GateA20 Fast Lets chipset control GateA20 Typematic Rate Setting: Key strokes repeat at a rate determined by the keyboard controller. When enabled, the typematic rate and typematic delay can be selected. The choice: Enabled/Disabled. Typematic Rate (Chars/Sec): Sets the number of times a second to repeat a keystroke when you hold the key down. The choice: 6, 8, 10, 12, 15, 20, 24, 30. Typematic Delay (Msec): Sets the delay time after the key is held down before it begins to repeat the keystroke. The choice: 250, 500, 750, 1000. Security Option: Select whether the password is required every time the system boots or only when you enter setup. System The system will not boot and access to Setup will be denied if the correct password is not entered at the prompt. 20 Setup The system will boot, but access to Setup will be denied if the correct password is not entered at the prompt. Note: To disable security, select PASSWORD SETTING at Main Menu and then you will be asked to enter password. Do not type anything and just press <Enter>, it will disable security. Once the security is disabled, the system will boot and you can enter Setup freely. OS Select For DRAM > 64MB: Select the operating system that is running with greater than 64MB of RAM on the system. Report No FDD For Win 95: Whether report no FDD for Win 95 or not. The choice: Yes, No. 3-3 ADVANCED CHIPSET FEATURES This section allows you to configure the system based on the specific features of the installed chipset. This chipset manages bus speeds and access to system memory resources, such as DRAM and the external cache. It also coordinates communications between the conventional ISA bus and the PCI bus. It must be stated that these items should never need to be altered. The default settings have been chosen because they provide the best operating conditions for your system. The only time you might consider making any changes would be if you discovered that data was being lost while using your system.

The default timings have been carefully chosen and should only be altered if data is being lost. Such a scenario might occurs if your system had mixed speed DRAM chips installed so that greater delays may be required to preserve the integrity of the data held in the slower memory chips. AGP Mode Select: This function allows you choose suitable AGP mode. The Choice: 1X, 2X, 4X AGP mode. 21 Delay Transaction: The chipset has an embedded 32-bit posted write buffer to support delay transactions cycles. Select Enabled to support compliance with PCI specification version 2. 1. The Choice: Enabled, Disabled. 3-4 INTEGRATED PERIPHERALS The "INTEGRATED PERIPHERALS" section mainly deals with I/O function. These functions will be necessary only when the system I/O malfunctioned or the system is unable to detects your CD-ROM or hard disk.

[. . . ] The following is the hardware installation and the software setups: 1. The speaker installation. Connect the front pair speakers to the Line-out jack of the audio adapter, and then connect rear pair speakers to Line-in/Rear jack of the audio adapter. The original Line-in can be moved to Aux-in. 2. The positions of the speakers Put your speakers the way the following picture suggests, so as to avail yourself to the best audio result. [. . . ]
