If you speak about a "RAID controller" on the motherboard itself, then
it is "fake RAID / win-raid".




not all onboard RAID controllers are fake RAID. But in this instance the
Promise 20276 is in deed a "fake" RAID controller.



You should get to use that with dmraid,
but up to now (with FC4) it is not supported by the anaconda installer.
You should see 2 drives instead of a single one.
Or did you setup Linux software RAID with DiskDruid?



finish the installation and reboot the machine, I have this error:

Missing operating system



When you use Disk Druid what partitions are created? Even if the drives
are set as a RAID you should see both drives in Disk Druid. If you want
to RAID them you can do it there.

You can try putting /boot on a non-raided partition.

Now that I think about, lvm2 may not even support booting from a raided
partition.

In the event that you have concerns, remember that it's only accessed
while the machine is booting (and during kernel updates/updates) and you
can always create a backup of it on a raided partition if you'd like.

lvm2 does support booting from RAID ( under FC3 at least) am I am using it. Just make sure that you install grub on BOTH drives. see the ROOT-on-LVM-on-RAID HOWTO at http://www.midhgard.it/docs/lvm/html/index.html

Also Read All of the Howto's to do with Software RAID, LVM and GRUB at
    http://tldp.org/HOWTO/HOWTO-INDEX/howtos.html

As it may not be as easy as you think

 for information on getting GRUB on to RAID

oops! DP may be right you can not have /boot on lvm2, grub does not anything about lvm (I am too use to lvm on HP).

However you can have /boot on RAID so you need at least 2 partitions, one so that grub can find the kernel with the other (or more) for the rest of the file systems.

The /boot partition must be either an ext2 or ext3 filesystem and your kernel need to support an initial ram disk (initrd).

Also if you make a custom kernel, later that is, leave the raid software as loadable modules else the auto activation of the raid devices at boot will not happen.

Sorry about the multi-posts on this, had to search for the doc that I used.
