IDE driver

[Cyber_Ghost]

Hi I'm writing an IDE driver and would like to get some pointers to info on doing it.

It should be a protected mode driver and should only be able to write and read a sector for starters.
Do I only need to write functions that read and write a sector or do I need something else too?
I've tried to write the functions but when I use them it makes VMware crash, so I guess I need to do something before I write a sector.
What is it?

Thanks,
Peleg

If you are looking for code samples, you will have to scour the available OSes which have matured to this level.

My OS is currently missing an IDE driver ... i'd be pretty interrested to see what your code looks like once you're done (especially if it's in C

I hope It'll be done sometime.
