Hi,

I wanted to install grml on a live stick with logical partitions, but got the 
error:

Fatal: installation on partition number >4 not supported. (BIOS won't support 
it.)

But as I bootet from an logical partition 5mins before I couldn't believe thats 
true, so I simple commented out these lines:

1808         if not os.path.isdir(device):
1809             if device[-1:].isdigit():
1810                 if int(device[-1:]) > 4 or device[-2:].isdigit():
1811                     logging.critical("Fatal: installation on partition 
number >4 not supported. (BIOS won't support it.)")
1812                     sys.exit(1)

and tried, and it worked! I don't know if it works on all modern Boards or only 
on some, or whatever. I have an Asrock Z77 Pro4 with P1.80...

So it's definitely not always right!
