ultra-violet (UV) light. If BIOS has to be upgraded, you need to remove EPROM from

EV6 Bus in the technology of Alpha processor from Digital Equipment Corporation. EV6 bus
uses both rising and falling clock edge to transfer data, similar as DDR SDRAM or ATA/66 IDE
bus.
EV6 Bus Speed = CPU external bus clock x 2.
For example, 200 MHz EV6 bus is actually using 100 MHz external bus clock, but the equivalent
speed is 200 MHz.
