I eventually figured out how to install Fedora 18 using the MBR-style
My Fedora 18 install media was a thumbdrive; what I discovered was that
if I did *not* instruct my motherboard firmware's UEFI menu to boot from
this USB device, then it seemed to pick it up as an old-style MBR boot
instead. From that point on, Anaconda seemed to assume the computer
had a BIOS, not UEFI.
It appears the Fedora 18 install image supports both BIOS/MBR and UEFI,
and the motherboard's firmware picks up the MBR if not explicitly asked
to boot the device as UEFI.
After picking through Anaconda and finding no option (i.e., a way to
install using an MBR boot instead of a UEIF boot), I suspect I could
achieve the same effect by manually creating an msdos partition table
on the target hard drive instead of a GPT partition table.
