9.11 SATA mode AHCI/RAID
AHCI is a standard for serial ATA controllers, which enables the software to communi
cate with these controllers, enabling faster access to hard drive data, such as by using
NCQ.
AHCI is set as default in BIOS. Older operating systems (e.g., Windows XP) do not
support AHCI mode by default. For this reason, corresponding AHCI drivers must be
loaded when installing the operating system so the hard drive is detected.
(cf. “F6 Disc” in Windows XP).
Alternatively, there is also the possibility of switching to the older IDE mode in BIOS
under “Integrated Peripherals” and “SATA Device”. However, this renders the advan
tages of AHCI unusable.
noax pre‐installed operating systems do not support IDE mode.
The corresponding AHCI drivers are available from our support.
The use of RAID functions is only possible with mainboard variant N11G and N11F
and if two SATA drives are connected to the mainboard.
RAID functionality can be ordered as an option.
RAID mode is not possible with the mainboard N11C variant.
A second SATA drive cannot be used.
Caution
It is possible to change to to RAID mode in BIOS at a later time.
But as a result the two SATA drives being used will be completely wiped.
