40 Well, you were right !
41 The live-cd SysRescueCd showed all the devices switched ; sdb instead of
42 sda.
43 Renaming all the devices and system was booting again.
44 Nevetheless, i felt that with AHCI BIOS Mode, the SSD was slightly less
45 reactive than the IDE Mode.
46 Do you think that could be possible ?
47 May be, i am completely wrong...
