Trouble booting computer from raid

Question

RAID

Background
I lacked the speed of the disk on the computer and it was decided to make a raid 0 + 1 of 4 disks. The motherboard supports a soft raid, the disks were purchased, configured, everything worked well.
Then I decided to try booting from the ubuntu 9.04 disk and see if that raid linux sees it as a single disk. The miracle did not happen, linux did not see the disk. Well, I think it's okay. I reboot back into Windows, and when I boot, I get a message that all 4 disks are now "Offline member". google search turned up this tricky solution: download the ubuntu live cd, install the dmraid package, and restart your computer

.
If you do this, everything is fine right away, all disks are marked “online member” at boot, the system starts up and works.

Question
Everything works only until the computer is turned off. As soon as the computer is turned off, the entire startup procedure with the ubuntu disk must be repeated. You can restart it, but you can not turn it off.

Here, in fact, the question is: what kind of garbage is this? How to fix it?

Answer 1

little information.
0. What was the main operating system under which this raid ran and everything worked?
1. Is it software (initially configured by means of OS) or hardware raid?
2. If hardware, did you look at the battery on the board / controller?
The first thing that comes to mind is to try to go into the settings of the raid itself and force the disks to go online.

Answer 2

Firstly, yes, I will join the requests - what kind of motherboard?
After installing dmraid in livecd, ubuntu starts to see disks? (Must start.) If so, you can at least save your data and system (image).
What can be seen in the BIOS before rebooting from Ubuntu (well, how does this fit with offline member)? What is seen after the reboot?
btw, 9.04 is a very ancient system, it is quite possible that it has an old mdadm that does not know how, but in a new one, for example, it can. Be guided by the kernel version: 2.6.32 does not know how, 3.2 can. (Dmraid itself is a much older solution than mdraid's support for bios fake raids).
