A computer's motherboard houses the processor and connects to input and output devices.
The Intel D815EEA motherboard, named "Easton," is part of a line of computer motherboards that uses the Intel 815 chipset. The board is no longer manufactured by Intel as of October 2010, and it is not compatible with any processors more recent than the Intel Pentium III. A motherboard is designed to work with a certain range of processors, in this case the Pentium III and certain Celeron processors, none of which is produced any longer.
Compatible Processors
Intel's "Easton" motherboard supports Pentium III processors with a 133 MHz or 100 MHz system bus or Celeron processors with a 66 MHz system bus. The processor must be in an FC-PGA package, or a PPGA for Celeron processors. FC-PGA and PPGA are different microprocessor package specifications. A microprocessor can have different package designs, the same way as a transistor or other component. FC-PGA means "Flip Chip-Pin Grid Array," a design that allows the chip to fit easily in a motherboard CPU socket while keeping the hottest parts of the chip away from the motherboard. PPGA stands for "Plastic Pin Grid Array," a similar package design used in Celeron processors.
The motherboard uses an Intel/AMI BIOS (basic input/output system), and the chipset includes an Intel 82815 graphics and memory controller hub, 82801BA input/output controller hub and an 82802AB firmware hub. There is no cache memory on the motherboard, as it is built into the processor.
Memory
The motherboard has three 168-pin DIMM memory sockets, and can support from 32 MB to 512 MB of SDRAM memory. Memory used must be the PC100 or PC133 type.
Connectivity
The D815EEA motherboard has one floppy drive port, two serial ports, one parallel port, four USB ports and PS/2 connectors for a mouse and a keyboard. It has two PCI bus master IDE ports, so four IDE hard drives can be connected in two master/slave configurations. It has line-level audio in and audio out jacks, a microphone input and a "Game Port" connector for sound.
Graphics
The graphics card is an integrated Intel 815 graphics accelerator. It supports adding a graphics card to the AGP slot.
Expansion Slots
The motherboard includes one AGP slot for a graphics card, five PCI slots and one CNR slot that is shared with one of the PCI slots.
