Installer and disk druid

[Bruno Costacurta]

Hello,

my PC has three disks. 
Two of them where previously configured as RAID1+LVM but this configuration 
was removed since : using fdisk I created other partitions and already 
installed other distros like Debian and Gentoo (via a single /boot partition 
shared by all distros via GRUB loader).

-- my problem :
I'm trying to install Fedora-9 on a specific partition but the Fedora 
installer (and disk druid) continues to see previous RAID1+LVM and not the 
specific disks !?!

-- my questions :
Where does Fedora grab its partition tables ?
How to modify / correct partitions if fdisk is not enough for Fedora ?

Thanks,
Bruno
