disable IDE write cache (Miscellaneous)

The Linux hdparm(1) command has an option to disable the on-disk IDE write cache.

-W     Get/set the IDE/SATA drive´s write-caching feature.

Does DOS have a way to accomplish the same thing?

Note that i mean the onboard cache built-in to the disk (ATA-1 and above), not OS-level caches such as LBACACHE.
