AR-B8172 User Manual 3 BIOS SETTING This chapter describes the BIOS menu displays and explains how to perform common tasks needed to get the system up. It also gives detailed explanation of the elements found in each of the BIOS menus.
AR-B8172 User Manual 3.1 Main Setup 3.1.1 AMI BIOS This is the interface of AMI BIOS: 3.1.2 Processor This part shows the auto-detected CPU specification. DM&P Semiconductor is the Vortex86SX 32-Bit Microprocessor, DDR2 128MB onboard, which is based on x86 structure. It is the x86 SoC (System on Chip) with 0.
AR-B8172 User Manual 3.2 Advanced Setup 3.2.1 IDE Configuration OnBoard PCI IDE Controller This can select the specification you wanted for the IDE device. This option specifies the channel used by IDE controller on the motherboard, Option Disabled Description Set this value to prevent the computer system from using the onboard IDE controller. Primary Set this value to allow the computer system to detect only the Primary IDE channel. This includes both the Primary Master and the Primary Slave.
AR-B8172 User Manual 3.2.3 SuperIO Configuration You can use this screen to select options for the Super I/O settings. Use the up and down keys to select an item. Use the and keys to change the value of the selected option. The settings are described on the following pages. The screen is shown below. Onboard Floppy Controller This item specifies the Floppy used by the onboard Floppy controller. The settings are Disabled or Enabled.
AR-B8172 User Manual 3.3 PCIPnP 3.3.1 Clear NVRAM Clear NVRAM during system boot. 3.3.2 PCI Latency Timer Allow you to select the value in units of PCI clocks for all of the PCI device latency timer register. Configuration option: 32, 64, 96, 128, 160, 192, 224, 248. Option 32 64 96 128 160 192 224 248 Description This option sets the PCI latency to 32 PCI clock cycles. This option sets the PCI latency to 64 PCI clock cycles. This is the default setting.
AR-B8172 User Manual IRQ This item can select the IRQ with Available or Reserved. And the default of IRQ3, 4 are Reserved and others are Available. When you set available, the specified IRQ is to be used by a PCI/PnP device; as you set reserved, the IRQ will reserved for legacy ISA devices. Interrupt Option Description IRQ3 IRQ4 IRQ5 This setting allows the specified IRQ to be used by a PCI/PnP Available device. This is the default setting.

AR-B8172 User Manual to disabled. Set this value to allow the serial port to use 3E8 as its I/O port address and IRQ 4 for 3E8/IRQ4 the interrupt address. If the system will not use a serial device, it is best to set this port to disabled. Set this value to allow the serial port to use 2E8 as its I/O port address and IRQ 3 for 2E8/IRQ3 the interrupt address. If the system will not use a serial device, it is best to set this port to disabled.
AR-B8172 User Manual 3.7 Exit 3.7.1 Save Changes and Exit Once you finished the selections, this option will allow you to determine whether to accept the modifications or not. Select the “OK” to save the change and exit, if you select “NO”, you will return to Setup utility. 3.7.2 Discard Change and Exit Select this option to exit the Setup without saving any change you have made in this session. Press “OK” will quit the Setup utility without saving any modifications.
AR-B8172 User Manual 4 BIOS REFRESHING, WATCHDOG AND GPIO PROGRAMMING 4.1 BIOS Refreshing The BIOS program instructions are contained within computer chips called FLASH ROMs that are located on your system board. The chips can be electronically reprogrammed, allowing you to update your BIOS firmware without removing and installing chips. The AR-B8172 provides the FLASH BIOS update function for you to easily to update BIOS.
