2.4. Microprocessor
The mainboard is designed to operate with the following processor:
Processor Type
FSB
Intel FC-PGA Celeron
Intel FC-PGA, FC-PGA2 Pentium III
66/100 MHz
100/133 MHz
VIA Cyrix C3
100/133 MHz
An onboard switching voltage regulator provides the required 1.3 to
3.5 volts for the processor. The processor sends five VID (Voltage
identification) signals to the switching voltage regulator. The
switching regulator generates the correct voltage for the processor.
2.5. CPU Packaging
PGA370 CPU are packaged in a FC-PGA, FC-PGA2 configuration.
2.6. AC 97 Codec
This mainboard features the AC 97 (ALC210A) codec. The AC 97
(ALC210A) Audio codec is compliant with the AC 97 2..2
specification, and supports 18-bit ADC (Analog Digital Converter)
and DAC (Digital Analog Converter) resolution as well as 18-bit
stereo full-duplex codec with independent and variable sampling
rates. Further features include support for four analog line-level
stereo inputs.
