when your system boots... watch very carefully, all the boot up messages
that is flyig by ...
- you will see the ide chipset it found ...
- you will see the partition tables
- you will see the ethernet drivers
once you know what part number ( chipset ) it uses for the ide controller,

insmod /lib/modules/`uname -r`/drivers/block/that-ide-chipset.o

hdparm -d 1 /dev/hda
