Well, that was standard intel RAID controler (onboard) I used to set up RAIDs on two 7200.12s.
I got Ubuntu live CD and may have any other distro - knoppix is no problem.
Under ubuntu I see whole hdd without any partition (under gparted, whole space is visible as 'unallocated'), do not know how to look into partition tables.
"Um, how do you set up two different raid volumes on two disks?"
After entering Intel Raid Option ROM I have 4 possibilities:
1. Create RAID Volume
2. Delete RAID Volume
3. Set disk to non-raid
4. Exit
After selecting 1. Create RAID Volume I can choose which RAID (1 or 0), how much space, and which HDDs.
If I make RAID0 sized 100GB I can select '1. Create RAID Volume' again and create another RAID Volume as long as space is available.
That way I created 2 Volumes (RAID0: 100GB, and RAID1 ~ 415GB).
On RAID0 I had about 4 partitions (linux home, linux root, boot, windows 7) and on RAID1 I had only 1 partition (ntfs).
Now I used 'testdisk' to find my lost partitions - without success. It found only 2 linux partitions without any files.
I do not want to recover any files from RAID0 - it is not possible.
But recovering from RAID1 should be easy...

NAME
vparremove - remove a virtual partition
SYNOPSIS
vp_name db_file]
DESCRIPTION
The command deletes a virtual partition previously created using the command. All resources associated with the virtual partition are made
available for allocation to other partitions.
Unintentional use of this command has serious consequences; therefore the user is prompted to confirm the operation unless the (force)
option is specified.
Options
recognizes the following command line options and arguments:
Specifies the unique name of the virtual partition which
is to be removed. Required.
Removes a virtual partition from the partition database
contained in db_file. If this option is omitted, the virtual partition is removed from the monitor's database. In this
case, the partition must be in the state to be removed. Thus it is an error to try to remove the current virtual partition,
the one in which the command is executing.
Specifies the force option.
Omits the confirmation dialog before removing the virtual partition. This option is intended for use by scripts and other
non-interactive applications.
SECURITY RESTRICTIONS
This command is restricted to processes owned by superuser.
When virtual partition flexible administrative capability is enabled, a virtual partition can only be removed from within a Designated-
Admin vPar.
RETURN VALUE
The command exits with one of the following values:
Successful completion.
One or more error conditions occurred.
EXAMPLES
Destroy the virtual partition in the partition database currently running in the monitor:
Destroy the virtual partition in the partition database currently running in the monitor using the force option:
Delete partition in partition database file
ERRORS
displays error messages on standard error for any of the following conditions:
o db_file does not exist, cannot be accessed, is not a virtual partition database file, or is corrupt.
o vp_name does not exist in the monitor's database or in db_file.
o vp_name in the monitor's database is in some state other than
o The command and the virtual partition monitor are at different revision levels.
o When the virtual partition flexible administrative capability is enabled and the local virtual partition is not a Designated-
Admin vPar.
