- 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
