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

Please give some idea regarding this. man 2 open, then look for O_DIRECT. -- tejun ^ permalink raw reply [flat|nested] 3+ messages in thread
