Description of problem:
In a system with 3ware IDE RAID controller cards and onboard SCSI, the 
RAID controllers are enumerated first in the device files, i.e. /dev/sda, 
sdb, then the onboard SCSI, /dev/sdc.  Anaconda will only allow you to 
create /boot on /dev/sda, even if the BIOS is set to boot only 
from /dev/sdc.  This creates a situation where everything must be 
repartitioned after anaconda finishes using a rescue disk, manually 
creating /boot on /dev/hdc and rewriting lilo.conf.  Anaconda should 
either allow you to create /boot wherever you want, or detect which disk 
the bios is seeing as 0x80 correctly.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Install 3ware IDE controllers
2. begin install of RH7.1 with linux expert option to allow the loading of 
3ware drivers from floppy at beginning of install
3. Attempt to create a bootable configuration within anaconda.
	

Actual Results:  LILO will hang with LI if anaconda is allowed to 
create /boot on /dev/sda (the 3ware RAID), and the BIOS is set to boot 
from /dev/sdc, Anaconda will not allow user to create /boot on anything 
but /dev/sda

Expected Results:  sucessful boot

Additional info:

Motherboard in test configuration was Supermicro P3TDE6 with serverworks 
HE chipset.  3ware controllers were two escalade 7800 cards.  On board 
SCSI is adaptec.
