Hi everybody,

I did also write a couple of lines IDE-harddisk interaction code (which is not the hard part in harddisk interfacing). The hard part (IMHO) is to figure out which disks are present and which parameters apply to them. I ended up whith a simple read-sectors and write-sectors commmand (tested) and a init functions wich detect the presence of your disks. I wrote also a partition-table-reader and began to read some ext2fs specs.
The disk interface seems to be currently the most wanted improvement to movitz. We have now 3 attempts. I guess its time for ext2 :).
