I have Asus Zenbook UX301 with Win8 preinstalled. I would like to have a Linux installed in dual-boot configuration. However, Windows is using the notebook 2 SSDs as intel RAID0 (rom-based RAID, fakeraid, imsm). I would like to keep that, as I like RAID0 and I would like to keep Win8 (I would have no way to reinstall it without purchasing new license if I break the RAID).
I enabled CMS in the bios and disabled secure boot.
When I boot into live USB (Ubuntu, same for Suse):
sudo mdadm --assemble --scan -e imdm and
sudo mdadm --examine /dev/md/imsm0 gives me:
ubuntu@ubuntu:~$ sudo mdadm --examine /dev/md/imsm0 /dev/md/imsm0: Magic : Intel Raid ISM Cfg Sig.

which shows to me that one of the disks is failing. The only new device created is:
/dev/md/imsm0 which points to
/dev/md127, while there are quite a lot of partitions on the RAID0 drive (at least 2 NTFS ones and win8 recoveries)
Chunk size is correct, but apparently something is wrong.
mdadm has a version of 3.3, downloading, compiling fresher version from the trunk does not help.
