If BIOS set to RAID (Intel Matrix) then you definitely can get in to
the RAID BIOS after the main BIOS does its thing, usually with ^I.
Just try tapping ^I a ton when any BIOS starts showing on the screen.
You can also try to set the BIOS-display delays longer in the main BIOS.

Also, check boot order and see if Intel RAID is set as the 1st boot
option.  If it is then for sure you have yourself a Intel RAID 1 there.

If you have no reason to suspect the working drive, and it passes diags
then I wouldn't worry too much, just put a replacement drive in and let
it rebuild.  If you're really concerned, do a dd image of the drive
using a linux boot CD or stick, preferably on a test bench system
without Matrix RAID (or with it off).  But that is more complicated
than just letting Matrix do its thing.

Booting with linux CD/stick will also show you if it's Matrix as it'll
build a dm-raid for it probably.  In fact, if you want to image the
drive, best to stop whatever RAID linux sets up for it (mdadm --stop)
before dd'ing the drive.

Again, all that is riskier IMHO than just replacing the drive, ^I'ing
and telling Matrix to rebuild and just rebooting into Windows (it'll be
dog slow, so be patient).
