Setting jumpers You can configure your card to match the needs of your application by setting jumpers. A jumper is the simplest kind of electric switch. It consists of two metal pins and a small metal clip (often protected by a plastic cover) that slides over the pins to connect them. To “close” a jumper you connect the pins with the clip. To “open” a jumper you remove the clip. Sometimes a jumper will have three pins, labeled 1, 2, and 3. In this case you would connect either pins 1 and 2 or 2 and 3.
Installing SDRAM (SODIMM) System Memory The reverse side of the Gene-4310 contains a socket for 144-pin dual inline memory module (SODIMM). The socket uses 3.3 V unbuffered synchronous SDRAM and is available in capacities of 16, 32, 64, or 128 MB. The socket can be filled in the SODIMM of any size, giving your GENE-4310 single board computer between 16 and 128 MB of memory. Supplementary information about DIMM Your Gene-4310 can accept regular PC-100 SDRAM SODIMM Module(with or without parity).
Clear CMOS (JP2 1~3) You can use JP2 pin 1~3 to clear the CMOS data if necessary. To reset the CMOS data, set JP2 to 2-3 closed for just a few seconds, and then move the jumper back to 1-2 closed.
IrDA connector (JP3) The IrDA connector (JP3) can be configured to support wireless infrared module, with this module and application software such as laplink or Win95 Direct Cable connection, user can transfer files to or from laptops, notebooks, PDA and printers. This connector supports HPSIR (115.2Kbps, 2 meters), ASK-IR (56Kbps) and Fast IR (4Mbps, 2 meters). Install infrared module onto IrDA connector and enable infrared function from BIOS setup.

CHAPTER 3 Award BIOS Setup This chapter describes how to configure the BIOS for the Gene-4310.
Starting setup The Award BIOS is immediately activated when you first turn on the computer. The BIOS reads system configuration information in CMOS RAM and begins the process of checking out the system and configuring it through the power-on self test (POST). When these preliminaries are finished, the BIOS seeks an operating system on one of the data storage devices (hard drive, floppy drive, etc.). The BIOS launches the operating system and hands control of system operations to it.

Power Advanced Power Management (APM) Management options. PnP/PCI Plug and Play standard and PCI Local Bus Configuration configuration options. Integrated I/O subsystems that depend on the intePeripherals grated peripherals controller in your system. Supervisor/User Change, set, or disable a password.
Load BIOS Defaults Load Setup Defaults Save & Exit Setup Exit Without Save 40 BIOS defaults are factory settings for the most stable, minimal-performance system operations. Setup defaults are factory settings for optimal-performance system operations. Save settings in nonvolatile CMOS RAM and exit Setup. Abandon all changes and exit Setup.
Standard CMOS setup When you choose the STANDARD CMOS SETUP option from the INITIAL SETUP SCREEN menu, the screen below is displayed.
This standard setup menu allows users to configure system components such as the date, time, hard disk drive, floppy drive, display, and memory. Online help for each field can be accessed by pressing F1. Date and Time Configuration The BIOS determines the day of the week from the other date information. This field is for information only. Press the left or right arrow key to move to the desired field (date, month, year).
If you do not want to select drive type AUTO, other methods of selecting the drive type are available: 1.Match the specifications of your installed IDE hard drive(s) with the preprogrammed values for drive types 1 through 45. 2.Select USER and enter values into each drive parameter field. 3.Use the IDE HDD AUTO DECTECTION function in Setup. Here is a brief explanation of drive specifications: •Type: The BIOS contains a table of pre-defined drive types.
- LBA (Logical Block Addressing): During drive accesses, the IDE controller transforms the data address described by sector, head, and cylinder number into a physical block address, significantly improving data transfer rates. For drives with greater than 1024 cylinders. Drive A Drive B Select the correct specifications for the diskette drive(s) installed in the computer. None 360K, 5.25 in 1.2M, 5.25 in 720K, 3.5 in 1.44M, 3.5 in 2.88M, 3.
Halt On During the power-on-self-test (POST), the computer stops if the BIOS detects a hardware error. You can tell the BIOS to ignore certain errors during POST and continue the boot-up process. These are the selections: • No errors: POST does not stop for any errors. • All errors If: the BIOS detects any non-fatal error, POST stops and prompts you to take corrective action.
BIOS features setup By choosing the BIOS FEATURES SETUP option from the INITIAL SETUP SCREEN menu, the screen below is displayed.
The displayed configuration is based on the manufacturer's SETUP DEFAULTS settings. Virus Warning When enabled, you receive a warning message if a program (specifically, a virus) attempts to write to the boot sector or the partition table of the hard disk drive. You should then run an antivirus program. Keep in mind that this feature protects only the boot sector, not the entire hard drive. NOTE: Many disk diagnostic programs that access the boot sector table can trigger the virus warning message.
Swap Floppy Drive This field is effective only in systems with two floppy drives. Selecting enabled assigns physical drive B to logical drive A, and physical drive A to logical drive B. Boot Up Floppy Seek When Enabled, the BIOS tests (seeks) floppy drives to determine whether they have 40 or 80 tracks. Only 360-KB floppy drives have 40 tracks; drives with 720 KB, 1.2 MB, and 1.44 MB capacity all have 80 tracks.
Shadow Software that resides in a read-only memory (ROM) chip on a device is called firmware. The AwardBIOS permits shadowing of firmware such as the system BIOS, video BIOS, and similar operating instructions that come with some expansion peripherals, such as, for example, a SCSI adaptor. Shadowing copies firmware from ROM into system RAM, where the CPU can read it through the 16-bit or 32-bit DRAM bus. Firmware not shadowed must be read by the system through the 8bit X-bus.
CHIPSET features setup By choosing the CHIPSET FEATURES SETUP option from the INITIAL SETUP SCREEN menu, the screen below is displayed.
The displayed configuration is based on the manufacturer's SETUP DEFAULTS settings. 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 SDRAM. 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.
USB legacy support When you set the USB controller to be Enable, then the item will be appear. It is in order to support applications and drivers in nonUSB-aware environments (e.g., DOS), the Host controller needs to provide some amount of hardware support for the emulation of PS/ 2 KB or PS/2 Mouse by their USB equivalents. Hardware monitoring support The Gene-4310 support onboard monitoring as CPU temperature, Fan speed, and Voltages for user reference.
Power management setup By choosing the POWER MANAGEMENT option from the INITIAL SETUP SCREEN menu, the screen below is displayed.
Power Management This option allows you to select the type (or degree) of power saving for Doze, Standby, and Suspend modes. This table describes each power management mode: Max Saving User Define Min Saving Maximum power savings. Only Available for SL CPUs. Inactivity period is 1 minute in each mode. Set each mode individually. Select time-out periods in the section for each mode, below. Minimum power savings. Inactivity period is 1 hour in each mode (except the hard drive).
MODEM Use IRQ Name the interrupt request (IRQ) line assigned to the modem (if any) on your system. Activity of the selected IRQ always awakens the system. Throttle Duty Cycle When the system enters Doze mode, the CPU clock runs only part of the time. You may select the percent of time that the clock runs.
PNP/PCI configuration setup By choosing the PNP/PCI CONFIGURATION SETUP option from the initial SETUP SCREEN menu, the screen below is displayed.
PNP OS Installed Select Yes if the system operating environment is Plug-and-Play aware (e.g., Windows 95). Resources Controlled By The Plug and Play AwardBIOS can automatically configure all the boot and Plug and Play-compatible devices. If you select Auto, all the interrupt request (IRQ) and DMA assignment fields disappear, as the BIOS automatically assigns them. Reset Configuration Data Normally, you leave this field Disabled.
Load BIOS defaults/Load setup defaults LOAD BIOS DEFAULTS loads the default system values directly from ROM. The BIOS DEFAULTS provides the most stable settings, though they do not provide optimal performance. LOAD SETUP DEFAULTS, on the other hand, provides for maximum system performance. If the stored record created by the setup utility becomes corrupted (and therefore unusable), BIOS defaults will load automatically when you turn the Gene-4310 on.
Integrated peripherals setup By choosing the INTEGRATD PERIPHERALS option from the initial SETUP SCREEN menu, the screen below is displayed.
IDE HDD Block Mode Select Enabled only if your hard drives support block mode. IDE PIO Modes (Primary Master/Slave) The four IDE PIO (Programmed Input/Output) fields let you set a PIO mode (0-4) for each of up to four IDE devices that the internal PCI IDE interface supports. Modes 0 through 4 provide successively increased performance. In Auto mode, the system automatically determines the best mode for each device.
ECP Mode Use DMA Select a DMA channel for the port. Onboard IR controller Enable or Disable the onboard IR controller, as default is Disable. When you set it to Enable. There are several item will be appear as below. IR Address select: Set IR address as (2F8H, 3E8H, 2E8H, 3E0H, 2E0H, 3F8H) IR Mode: Setup IR mode as (IrDA, ASKIR, FIR, CIR) When you set it to FIR mode. You also have to setting the FIR DMA. IR Transmittion delay: enable or Disable IR transmittion delay.
