That's quite odd... BTW, how did you find out this? In the definition
of the LBA interface, BIOS shouldn't write more than a specified size.

Version 4.8! Does anybody on this list know EDD 4.x? AFAIK, the
latest version is EDD 3.0, but is there another specification
published by other than Phoenix?

If you change this line to:

drp.size = sizeof (drp) - sizeof (drp.dummy);

does the output change?
