Accessing Compact flash ???????

Environment in which system works:

Microblaze softcore processor on spartan 3 fpga board
compact flash, acting as a mass storage.

How to access the compact flash in embedded applications

CHS  or LBA??

I got no clue how to access, it would be great help if i could
understand in and out of doing tht becoz i need to write a code in C

Google for compact flash, or have a
look at the sandisk site.
