Hi,

I am puzzled by the way Linux handles the EIDE interface. Can some one
please help me. I have the following questions.

1. How can I figure out the Cylinder/Head/Sector the block belongs to
inseide the device drive (src/linux/drivers/block/ide.c - do_rw_disk
function) if the disk is configured in LBA mode ?

2. How does the device driver do the mapping of block number ->
cylinder/head/sector if LBA mode is used ?

3. Where can I find some information about EIDE Register specifications?

Some help will be grately appreciated.

Thank you
Ravi
