Enable 8GByte or 2GByte Drives
This setting affects how the BIOS reads the disk drives. Drive geometries
can be toggled between 8 GB and 2 GB. The default is 2 GB. The drive
geometry must be set, and then the drive must be formatted (or reformatted).
The default BIOS geometry of the controller is set to 2 GB. This means that
the BIOS only sees the first 2 GB of any drive that has been configured on
the controller. This is adequate in most applications, since BIOS is only used
to boot the operating system. However, it does mean the operating system
must be installed in the first 2 GB of the capacity of the configured drive. If
this is not adequate, the BIOS geometry can be changed to 8 GB, allowing
the BIOS to see the first 8 GB of capacity.
m Caution
Changing this setting after data has been stored can
make the data unreadable. If you have already
configured your array and have stored data, you
should not change this setting.
