Hi,

I doubt that this is caused by int 13, as grub2 doesn't change it.
Besides, the boot sector is read properly in grub2, so int 13 should
be working.

I have thought of another possible reason for this. In grub2, %dh is
0, perhaps it should be set to the partition number. Please test if
the new patch works.

Hi,

To get more insight and see whether the values are proper,I dumped the structure members.

So for the commands:

set root=(hd0,1)
chainloader +1

This is disk and partition strucure member values.

disk->name=(hd0,1)
disk->has_partitions=1
disk->id=0x80

For the partition p,

p->offset=0
p->index=0
p->data=0
p->start=0x3f
p->len = 0x0
p->offset=0x4e1edec
p->partmap->name=(null)
part_addr=0x7be

And this is the dump from the mbr:

000001b0   00 00 00 00 00 00 00 00     81 eb 09 00 00 00 80 01  |................|
