Cyrix/IBM 5x86/6x86 CPU configuration tool


Allows one to modify the internal configuration registers in the 5x86 and 6x86 CPU. These include specifying non-cacheable memory areas (important for e.g. graphics cards), I/O delays, cache write policy (WB/WT), write-gathering, and also enable an automatic standby mode where a CPU "halt" instruction cuts down power by a factor of 70 (from 20 Watts to 0.3 Watts for the 6x86 P133+) when the CPU is idle. Especially the CPU power reduction cuts down on most temperature-related problems on many motherboards.
