4-6 DAC960PG Installation Guide
Enable 8 GByte or 2 GByte Drives
This option can be toggled between 8 gigabyte and 2 GB drive geometries.
The default is 2 GB. This setting affects how the BIOS reads the disk drives.
The drive geometry must be set and then the drive must be formatted (or
reformatted).
The DAC960PG ships with the default BIOS geometry set to 2 GB. This
means that the BIOS will only be able to see the firsst 2 gigabytes of any
drive that has been configured on the DAC960PG. 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 somewhere in
the first 2 GB of the configured drive’s capacity. If for some reason this is
not adequate, the BIOS geometry can be changed to 8 GB. This will allow
the BIOS to see the first 8 GB of capacity.

Caution
If you have already configured your array and have
stored data, you should not change this setting.
Changing this setting after data has been stored will
have an effect similar to changing your stripe size. It
will make your stored data unreadable.
