So from what i understand, the IDE on MBX board is done by the W83C553F 
chip which i suppose it's not present on other boards, am i right? 
If nobody minds, i'd like to give it a shot at making it work, even if it's
MBX specific... i could really use a hard drive on my board

So, any hints about where to begin?
Right now i'm using 2.2.13. It seems to initialize the IDE interface, but the
drive is not detected.
I'm thinking about using 2.3.28, it seems to have more support for this kind of
stuff, but it's a mess when it comes to building the kernel...
