Socket 7 microprocessors. This mainboard utilizes the VIA MVP3 100MHz

(http://www.tyan.com/support/html/socket_7_compatibility.html). The Trinity

ATX also has 100MHz Front Side Bus support, which allows you to take full

advantage of 100MHz SDRAM memory modules.

expandability have been designed into the Trinity ATX. With I/O and drive

controller support built onboard, the one AGP slot, five PCI and two ISA slots

(one shared, seven usable) are free for numerous add-on expansion cards.
