Negate-Lock-Pin (registered version only!) =============== On machines equipped with Cyrix/TI/IBM CPUs the state of the Negate-Lock pin can be enabled. With this set, previously noncachable locked cycles are executed as unlocked cycles and therefore, may be cached. This results in higher performance. You may estimate a speed increase of up to 10% on machines without L2 cache as laptops and up to 5% with 256 PB cache. To enable this, start PC-CONFIG from command-line: config nolock To disable type: config nolockoff Testresults: ============ Below you find testresults made with the 3 popular windows-benchmarks Wintach V1.2, Speedy V1.1 and ZD Winbench 96. Larger values mean faster speed.
