II. FEATURES The ASUS MEL-B Motherboard The ASUS MEL-B motherboard is carefully designed for the demanding PC user who wants many intelligent features in a small package. Specifications • Intel Processor Support: Supports Intel Celeron processors (300MHz and faster) designed for Socket 370 and packaged in a Plastic Pin Grid Array (PPGA).
Page 9
• ACPI Ready: ACPI (Advanced Configuration and Power Interface) is also imple- mented on all ASUS smart series motherboards. ACPI provides more Energy Saving Features for future operating systems (OS) supporting OS Direct Power Management (OSPM) functionality. With these features implemented in the OS, PCs can be ready around the clock, yet satisfy all the energy saving standards.
