System BIOS Setup
Due to frequent update of system BIOS, the actual options available in your system board BIOS setups may vary comparing with this manual. If technically necessary, we would provide a special insert for instruction of the difference in regard to any changes of the BIOS setup option.
Load Setup Defaults
There is a set of BIOS values stored in the ROM files: The "Setup" default values The "Setup" default values are those settings which should provide optimum performance for the system. They are the best case default values. This set of default values can be loaded by using the "Load Setup Defaults" option in the main BIOS menu when you first entered the setup utility.
Standard CMOS Setup Option
Primary Master & Slave, Secondary Master & Slave Drive Types
According to your actual equipment, you can select the type of hard disks for C, D, E, & F from 'Not Installed' to type 46 for standard hard disks. As for type 47, user may define by himself. If a ATAPI IDE CD-ROM is connected to any on-board IDE port, the HARD DISKS "Type" should be set to "None". The DOS CD-ROM driver or the Win95 built-in driver will handle the communication by themselves. You may also use the "IDE HDD Auto Detection" option in the Main Menu to allow the system to detect and enter these information for you.
BIOS Features Setup
Virus Warning
This function, If enabled, will detect boot sector viruses and warning will be given when a program attempted to change boot sector information.  
CPU Internal & External Cache
These options allows user to enable or disable the on-board (External) and the on-chip (CPU Internal) cache memories (SRAM) when special peripheral or software implemented indicate such requirement.
Security Option
This option allow a password be set up so that a password will be needed to enter the CMOS Setup or to boot the system including entering CMOS Setup. After this option is enabled, you must use the "Password Setting" option in the main menu to setup your password. If in any case the password is lost or forgotten, the jumper JP 5A - Clear CMOS can be used to clear the configuration.
Chipset Features Setup
Most of the options in this group have major influence to the system. If options are not set properly, it may not only greatly affect the performance, but also it may bring the system down unexpectedly in most cases. Therefore, it is only wise to leave the defaults alone unless there are specific reason to do any change.
Auto Configuration, and AT Bus Clock
The Auto Configuration option should be always enabled for the system to automatically configure the AT bus clock to AT standard by detecting the system clock rate.
RAS, & CAS Precharge Times
DRAM must continually refreshed or it will lose its data. This option allows you to determine the number of CPU clocks allocated for the Row Address Strobe, and Column Address Strobe to accumulate its electrical charge before the DRAM is refreshed. The defaults are "5" and "1" respectively.
L1, and L2 Cache Policies
These 2 options allow you to control the CPU internal cache and the secondary cache to use either "Write Back" or "Write Through" cache policies.
Cache Read Burst, Cache Write Burst
The defaults are "3-2-2-2", and "4-2-2-2" respectively.
Power Management Setup
Power Management
This option served as a master switch to turn-on the power management.
Doze, Standby, and Suspend Modes
Defined the length of time of continuous inactivity before the system enters into different PM modes. The Suspend Mode is not implemented.
PCI Configuration Setup
Unless otherwise required, do not change the PCI default settings.
Integrated Peripherals Setup
IDE HDD Block Mode
This option, if enabled, instruct the hard disk to read multiple blocks of data from the disk for one read request. You must refer to your hard disk information to be certain your drive support this feature.
IDE Primary & Secondary, Master & Slave PIO Modes
Rather than have the BIOS issue a series of commands to effect a transfer to or from the hard drive, PIO(Programmed Input/Output) allows the BIOS to tell the hard drive controller what it wants and lets the controller and the CPU to perform the complete task themselves. This method is simpler, more efficient, and so is faster. The BIOS supports five modes(0 through 4) and can be set to "Auto" for each individual hard drive.
FDD Controller, Serial Port 1 & 2
Use these options to enable or disable the respective on-board controllers.
On-Board Parallel Port, Parallel Mode, and ECP DMA Channel
LPT port address can be selected by using the first option. The second option allows the setting of the enhanced modes for the parallel port. If "ECP" or "EPP+ECP" is enabled in the "Parallel Mode" option, use the "ECP Mode Use DMA" to select DMA channel for the ECP Mode.
Exiting Setup Utility
At this point, you can either choose to confirm your setup entries and exit by using "ESC" key and taking the "Save & Exit Setup" or the "Exit Without Saving" option to restore the original setup parameters and exit. After you highlight the desired option and press <<ENTER>>, the system will reset itself. The new or original setup parameters, depend on the option which you have chosen, will become the current setting.
