Subject: [PATCH] Fix ghost devices under /sys/firmware/edd

Some BIOSes do not always set CF on error before return from int13.
The patch adds additional check for status being zero (AH == 0).


Do you have any evidence that there aren't any BIOSes which leave AH != 0 on legitimate success? If so, you have turned a nuisance bug into something that could cause install failures.
