OK, now I understand. I call it "pseudo-hw-raid". It still depends on |
| 7 |
software driver and cpu. |

I agree. And that is what I'm trying to use, linux software-raid built |
| 12 |
in kernel... |

Yes, of course. All partitions are marked as "auto-detect" (fd), and |
| 18 |
raid support is in my kernel (not as module). As I wrote previously, |
| 19 |
all md's are autodetected without any problem: |

md: bind<hdg1> |

md: running: <hde1> <hdg1> |
| 31 |
raid1: raid set md0 active running 2 out of 2 mirrors |
| 32 |
md: ... autorun DONE |

<similar for all md's> |

I think I can unselect options 1. and 3. (md-support is in kernel, and |
| 49 |
partitions are marked as type "fd - Linux raid autodetect"). |
| 50 |
|
| 51 |
Concerning 2, I'm not sure if I understand correctly: |
| 52 |
Do you mean turning off initramfs support in kernel-configuration? |
