Because I have an older system with the 8 GB barrier in the BIOS. All boot
sectors need to be located within the first 8 GB to boot with this AMI BIOS.
Linux use the BIOS only for booting. All you have to do is, to install the
boot-Partition within the BIOS limit and the rest of the disk is available
after their IDE-drivers have loaded.

Here are some limitations of the older system BIOS:

AMI-Barriers:

Until end of 97, beginning of 1998 the BIOS was limited to 8 GB.

(2 GB, 4 GB, 8 GB) on Phoenix equipped systems.

AWARD-Barriers:

      Date Barrier
      Until End of 1994 504 MB
      Until End of 1997/Begin of 1998 8 GB
      Until Mid of 1999 32 GB
