Is it my fault that SATA drives dissapear from the bios if ahci is activated in the bios?
Weird. Do you get a "AHCI Controller" screen after the normal BIOS screen and before the resource listing (that with the IRQs)? I get that with the AMI Bios on a Gigabyte board. What board/BIOS do you have? (just curious)
See my other post wit links to photos to what I see. When I attempt to boot in AHCI mode I see this:
I followed up there.
Board is MSI P45 Diamond, (dmidecode says: MS-7516). Bios is "American Megatrends Inc.", which I assume is "AMI", V1.5, 10/10/2008.
Ah.
The choices I have, and it is a new board, are "ide, raid, ahci". I have to use "ide", which in fact means sata, hotplug and all working fine.
AFAIR hotplug and NCQ work only in AHCI mode ...
Hotplug is indeed working for me, and it is in in IDE mode. See photos.
Weird. It shouldn't, as IDE-mode does not support connect/reconnect, maybe your board cheats :))
NCQ I don't know what it is.
"Native Command Queueing", i.e. the Controller can reorder requests to better fit data-layout on disk, i.e. it can reduce head movement significantly if e.g. two processes request data from opposite ends of the disk. Without NCQ it might be: process1: get sector 600 process2: get sector 160000 process1: get sector 601 process2: get sector 160001 ... With NCQ, the disk can change that to process1: get sector 600 process1: get sector 601 ... process2: get sector 160000 process2: get sector 160001 ... You get the gist?
