ok, after applying the "second take" search.c patch, I get:

So it's something triggered by a condition in the real bootloader.
sh:grub> search -l ""
Segmentation fault
This should be fixed in Subversion. My mistake. Please test it. The
patch for unifying search won't help solve this problem.
now I get:
sh:grub> search -l ""
hd0,7 hd0,1
sh:grub>
Good.
In real grub:
ls -l
hd0: Partition table
Partition hd0,1: Filesystem cannot be accessed
Device hd1: filesysetm cannot be accessed
Device hd2: filesystem cannot be accessed
Device fd0: Filesystem cannot be accessed
error: no such disk
With the second-take patch I get the same result.
It looks like there are several issues are at play here. There is an
issue with hd0,1, and then there is an issue with error handling. I
think we should deal with the error handling first, as it will stand in
the way.
With real grub and the first and second-take patch I get:
search -l ""
hd1,5 hd1,3
It looks like hd0 is ignored.
Yes.
I still get that with 'search -l ""' on real grub, but now (SVN 2402?)
grub-emu shows:
sh:grub> search -l ""
hd0,7 hd0,1 hd3,5 hd3,3
sh:grub> ls
