Drive Configuration
The
Here you can turn off the primary (and only) ATA controller, disabling the on-board SSD device and IDE connector,
maybe in favor of external hardware. Independently, you can disable all IDE drive support (INT 13) in the BIOS,
including the capability to boot from IDE. You can also switch the on-board SSD from primary Master to Slave
device.
To work around potential incompatibilities it is possible to disable DMA or force specific transfer modes. Note
however that as soon as the OS has loaded its native, BIOS-independent ATA driver it will probably override these
restrictions.
If "80-Conductor Cable Sense" is set to the default "GPIO 05", the board will recognize modern 80-wire IDE
cables automatically and allow faster transfer rates if one is detected. Changing this option allows overriding the
detection if necessary.
Specifically, if no cable is attached, the missing 80-wire signal will force the chipset to assume 40-wire cabling.
This will limit the on-board SSD to lower UDMA2 speed. Therefore, if you havn't anything connected to the on-
board IDE connector, but are only using the SSD, set "80-Conductor Cable Sense" to "Force 80 conductor cable"
to gain maximum performance. Don't do this if you are planning to connect a device via an old 40-wire IDE cable.
As SSD standalone will probably be the most common case, the "Force 80" setting has been made the default
with BIOS SRLX0013 (not pictured here). To use an old 40-wire cable it has to be manually changed back to
"Auto" (previously "GPIO 05" but renamed to be more self-explanatory).
