There is a lot of confusion available from articles on the Internet

In order to go that large, the disk must be labelled, via partd, as type
GPT.
Ok so far.
Now, is it possible to use fdisk to cut off 100MB or so for a normal
/boot partition?
It seems that labelling a disk as GPT does not stomp the MBR, but does
affect the partition table. Is this correct?
fdisk has issues with > 2TB.
If I create a 100MB partition using fdisk, and then label the disk as
GPT, can I start the large partition with the first cylinder > than what
I cut off for /boot and expect it to be seen?
Anaconda complains that GPT is not bootable. Is that system specific,
BIOS specific, anaconda error reading the BIOS, ???
Here is the specific scenario:
An intel based server, with 10 1TB drives attached to a SATA RAID
device. The RAID is level 5 with 9 drives and a hot spare.
If it is a hardware raid controller it is generally possible to "partition" it
in the hardware raid controller (either separate the big r5 into 2, or define 2
separate raid's over the same disks with one only taking up a small part of
everything) to setup the boot device <2TB. I have done this before with 3ware
and Areca controllers, and would bet almost all of the raid controllers have
this ability.
Check the manual for the raid controller, it may or may not be able to do it.
