And the scam is adding this to mobo features as a "RAID" and an attempt to make this pass as if it was a hardware RAID. GRUB currently considers mdX as a non-available through BIOS unless user overrides it in device.map, we need to add a logic to handle the fakeraid as a BIOS disk. It's possible to add support for intel RAID but it will be useless since the member disks aren't available through BIOS to begin with. > > --=20 Regards Vladimir '=CF=86-coder/phcoder' Serbinenko --------------enigBD9F3165ABABB94E71D32DF7 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iF4EAREKAAYFAk82W/IACgkQNak7dOguQgloeAD9F/sKRBHptNnCyqnXxoSzt6o4 B/T4oj9kT/3278wuLX4BAI/VkJ7Pjx1Zl9R8BITyPe4qfbuOJvvBW5iBcm8jUd/q =cw4a -----END PGP SIGNATURE----- --------------enigBD9F3165ABABB94E71D32DF7--
