This command does not force an MSDOS MBR partition type. It just forces 
fdisk to use the MSDOS partition table in the protective MBR. It does 
not touch the GPT header and table. This trick has worked for me on a 
number of machines with non-compliant BIOSes.

A friend told me he observed that a GPT disk label created by fdisk has 
a wrong value in its header (I do not remember which one) which may 
cause some firmwares to consider the GPT disk label as invalid. However 
a BIOS should not care about the partition table whatever format it has 
(unfortunately some wrongly do, and we have to deal with it). Note that 
the Debian installer uses libparted to create new disk labels.
