Confirmed, the problems are fixed. Thank you.
I think it is problematic that you can now generate invalid
boot menus with Boot Manager, because it allows you
to select partitions from different drivers (before your changes
only partitions from the first drive could be selected).
Booting from a partition on another than the boot drive won't
work until B_GET_BIOS_DRIVE_ID is implemented.
For a quick fix the list of partitions should show only
the partitions from the target drive selection on the first
Boot Manager page.
