while booting a menu can be called before any OS is loaded (iirc) |

i think so... |
| 13 |
if you really want to use it look for the "dmraid" boot option. |
| 14 |
but in fact this silicon pseudo-raid-controller does not speed up |
| 15 |
anything, all the IO is still done by the CPU, and linux is not able to |
| 16 |
use the controller without the use of the device mapper (that is what |
| 17 |
"dm" is short for) and some magic I never got around to do (don't |
| 18 |
remember exactly, driver issues) |

I stopped trying to get it running after I found out software raid under |
| 21 |
linux is much easier: you just need the sata-drivers for the controller, |
| 22 |
the raid-drivers, and only if you intend to use LVM, the device-mapper, |
| 23 |
so no aditional driver for the so-called raid-controller is needed. |
| 24 |
Additionally you can use both raid-1 and raid-0 with different |
| 25 |
partitions on the same two disks. |

| 27 |
if you go the controller-raid way you only need the device mapper plus |
| 28 |
whatever that one needs to access the raid. |
