Zida Tomato BIOSes for Socket 370
Socket 370 (also known as the PGA370 socket) is a CPU socket first used by Intel for Pentium III and Celeron processors to first complement and later replace the older Slot 1 CPU interface on personal computers. The "370" refers to the number of pin holes in the socket for CPU pins. Socket 370 was replaced by Socket 423 in 2000.
