JSI Tip 4870. Your Windows 2000 Professional stops responding, your cursor is erratic, and performance is slow?

The subject behavior can be caused by having the BIOS processor cache setting set to write-through instead of write-back.

"Write-back is a cache architecture in which data is written to main memory only when the data is forced out of the cache. Write-through is a cache architecture in which data is written to main memory at the same time that the data is cached. Write-back caching yields somewhat better performance than write-through caching because write-back caching reduces the number of write operations to main memory."
