DOS ain't dead

disable IDE write cache (Miscellaneous)

There are some low-level DOS HDD tools like Hitachi HDF tool that can enable/disable cache. On most HDD I saw the write cache was disabled by default (let OS to enable it). I'm not sure if the setting is persistent or it will return back to default after drive reset/power cycle...

DOS gives me freedom to unlimited HW access.
