There are such files for the normal IDE drive, but not for the SATA disks.

The two disks are 100% identical, I do not see no difference in both 
folders, except some "mbr_signature" in int13_dev80. Also the contents of 
all the data is the same. Even the BIOS does not make it easy to 
distinguish between both channels - you see what you've selected by what 
is booted ;-)

I'm trying to find someone, who has another SATA drive laying around or 
some IDE-to-SATA adaptor, so the information is not identical.
