NOTE: Generally, the BIOS default settings have been carefully chosen by the system manufacturer to

provide the absolute maximum performance and reliability. It is very dangerous to change any setting without full understanding. We strongly suggest that

DO NOT update your BIOS if the system works perfect. DO NOT change any setting unless you fully understand what it means.

If the system does not work smoothly after changing the BIOS setting, follow the procedures that described before to enter setup program then load the default to back to the manufacturer default setting.

If the system is no longer able to boot after changing the setting, clear the data stored in RTC CMOS is the only way to recover it. To reset the RTC CMOS data, you need to change the jumper cap of JP1 from 1-2 close to 2-3 close, then set to default 1-2 close again. After that, you should get into BIOS setup program and choose LOAD SETUP DEFAULTS to get original manufacturer default setting in your CMOS.

VGA device's palette registers and the ISA VGA device palette registers, permitting the palette registers of both devices to be identical.

Offboard PCI IDE Card

This option specifies if an offboard PCI IDE controller adapter card is used in the computer. You must also specify the PCI expansion slot on the motherboard where the offboard PCI IDE controller card is installed. If an offboard PCI IDE controller is used, the motherboard onboard IDE controller is automatically disabled. The settings are Disabled, Auto, Slot1, Slot2, Slot3, Slot4, Slot5, or Slot6. If Auto is selected, AMIBIOS automatically determines the correct setting. This option forces IRQ 14 and 15 to a PCI slot on the PCI local bus. This is necessary to support non-compliant PCI IDE adapter cards.

Offboard PCI IDE Primary IRQ

This option specifies the PCI interrupt used by the primary IDE channel on the offboard PCI IDE controller. The settings are Disabled, Hardwired, INTA, INTB, INTC, or INTD.

Offboard PCI IDE Secondary IRQ

These options allow you to specify the bus type used by each DMA channel. The settings are PnP or ISA/EISA .

IRQ3 IRQ4 IRQ5 IRQ7 IRQ9 IRQ10 IRQ11 IRQ12 IRQ14 IRQ15

These options specify the bus that the specified IRQ line is used on. These options allow you to reserve IRQs for legacy ISA adapter cards. These options determine if AMIBIOS should remove an IRQ from the pool of available IRQs passed to devices that are configurable by the system BIOS. The available IRQ pool is determined by reading the ESCD NVRAM. If more IRQs must be removed from the pool, the end user can use these options to reserve the IRQ by assigning an ISA/EISA setting to it. Onboard I/O is configured by AMIBIOS. All IRQs used by onboard I/O are configured as PCI/PnP. IRQ12 only appears if the Mouse Support option in Advanced Setup is set to Disabled. IRQ14 and 15 will not be available if the onboard PCI IDE is enabled. If all IRQs are set to ISA/EISA and IRQ14 and 15 are allocated to the onboard PCI IDE, IRQ9 will still be available for PCI and PnP devices, because at least one IRQ must be available for PCI and PnP devices. The settings are ISA/EISA or PCI/PnP
