The Intel® 815 chipset, codenamed “Solano,” was released in 2000 for Intel Pentium III and Celeron processors using the Socket 370 interface. It succeeded the popular 440BX chipset and introduced official support for a 133 MHz front-side bus and PC133 SDRAM. The 815 integrated Intel Extreme Graphics, enabling basic onboard video without a separate graphics card, though performance was modest. It also added Ultra ATA/100 storage support, USB connectivity, and AC’97 audio capabilities. Variants like the 815E and 815EP offered different graphics and expansion options. Widely used in business and consumer desktops, Solano helped transition PCs toward more integrated, cost-efficient motherboard designs.
