diskstart: if no partition info is available, use bsHiddensyslinux-4.00-pre63
If we have no partition information available, use the bsHidden field (which is set by the extlinux installer in the case of non-FAT). This gives at least a hope of working correctly (for < 2 TiB disks, at least) with the stock Vista/Win7 MBR. Also, add a check for partition type != 0. This helps catch the case when DS:SI points into all-zero memory. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
