APIC Mode
The A PIC Mode BIOS feature is used to enable or disable t he motherboard’s A PIC (Advanced Program-
mable Interrupt Controller). If your single-processor motherboard supports APIC and you are using a Win32
operating system (Windows NT, 2000 and XP), it’s recommended that you enable this feature to allow faster
and bett er IRQ handling. If you are using a multiproces sor motherboard, you must enable this feat ure
because it’s required for IRQ handling in multiprocessor s ystems. Choose “E nable” when choosing Win-
dows 2000 or Windows XP as your operating system.
MPS Version Control for OS
This feature is only applicable to multiprocessor motherboards as it specifies the version of the Multi-
Processor Specification (MPS) that the motherboard will use. The MPS is a specification by which
PC manufacturers design and build Intel architecture systems with two or more processors.
Small Logo (EPA) Show
If enabled, the small logo of the EPA will show.
Spread Spectrum
This item allows you to enable/dis able the spread spectrum modulator to reduce E MI. The choices are
Enabled and Disabled.
After you have made your selections in the Advanced BIOS Features setup, press <ESC> to go back to the
main screen.
4.9 Advanced Chipset Features
Since the features in this section are related to the chipset in the CPU board and all are optimized, you are
not recommended to c hange t he default sett ings in the setup table, unless you understand the chipset
features.
This sect ion allows you to configure the sys tem based on the s pecific features of the installed chipset.
This chipset manage bus s peeds and acc ess t o sy stem memory resources, such as DRAM and the
external cache. It also c oordinates communications between the conventional ISA bus and the PCI bus.
The default settings have been chosen because they provide the best operating conditions for your system.
The only time you might consider making any changes would be if you discovered that data was being lost
while using your system.
The first chipset settings deal with CPU access to dynamic random access memory (DRAM). The default
timings have been carefully chosen and should only be altered if data is being lost. Such a scenario might
well occur if your system has mixed speed DRAM chips installed so that greater delays may be required to
preserve the integrity of the data held in the slower memory chips.
Selecting Advanced Chipset Features on the main program screen displays this menu:
