Hi all,
       I am using fedora core -3 with kernel 2.6.10. I want to 
read/write a sector from/to the HD with out kernel caching. Basically my 
aim is to communicate directly with the ide drivers so that I can bypass 
the kernel cache. Please give some idea regarding this.

Regards
Dipti Ranjan Tarai

man 2 open, then look for O_DIRECT.

Why wouldn't the (obsolete) RAW driver (CONFIG_RAW_DRIVER) or (better)
O_DIRECT work for you??
