BIOS Setup

Execute Disable Bit

Execute-Disable Bit capability is a robust hardware feature, detectable using the CPUID instruction, that protects against malicious software executing code on IA- 32 systems.

C1E Support

This item allows you to enable/disable the C1E power management feature which can also drop clock speed and voltage on the processor.

Hardware Prefetcher

This item allows you to to enable/disable the hardware prefetcher, or in other words – hardware prefetch mechanism.

Adjacent Cache Line Prefetch

This item allows you to enable/disable the adjacent cache line prefetch mode. W hen disabled, only one 64 byte line from the 128 byte sector is prefetched (which contains the requested data). When enabled – both lines are prefetched no matter whether they have or have not the requested data.

Full Screen LOGO Display

This item enables you to show the company logo on the bootup screen. Settings are:

[Enabled]

Shows a still image (logo) on the full screen at boot.

[Disabled]

Shows the POST messages at boot.

ACPI APIC support

This field is used to enable or disable the APIC (Advanced Programmable Interrupt Controller). Due to compliance with PC2001 design guide, the system is able to run in APIC mode. Enabling APIC mode will expand available IRQ resources for the system.

Boot Up Num-Lock LED

This setting is to set the Num Lock status when the system is powered on. Setting to [On] will turn on the Num Lock key when the system is powered on. Setting to [Off] will allow users to use the arrow keys on the numeric keypad.

MPS Configuration

This field allows you to select which MPS (Multi-Processor Specification) version to be used for the operating system. You need to select the MPS version supported by your operating system. To find out which version to use, consult the vendor of your operating system.

1st Boot Device

The original IBM PCs loaded the DOS operating system from drive A (floppy disk), so IBM PC-compatible systems are designed to search for an operating system first on drive A, and then on drive C (hard disk). However, modern computers usually load the operating system from the hard drive, and may even load it from a CD-ROM drive.
