SUMMARY
When initializing certain Cyrix processors, Windows NT 4.0 will disable the CPU write-back cache to prevent serious system problems.
MORE INFORMATION
Certain Cyrix processors are known to cause serious problems with Windows NT 4.0.
If Windows NT detects certain Cyrix processor steppings, it will disable the L1 w/b (write-back) cache.
This will reduce performance but will guard against systemwide problems caused by the write-back cache, thus preventing data-loss.
The Cyrix products discussed here are manufactured by Cyrix Corporation, a vendor independent of Microsoft; we make no warranty, implied or otherwise, regarding these products' performance or reliability.
