Video Resolution

The ClearView Quadro4 video driver that comes pre-installed on ClearCube PC
blades supports video resolutions as high as 1280 x 1024. If you require video
resolutions greater than this, you need to uninstall the ClearView Quadro4 driver from
the blade and install the standard, high resolution Quadro4 video driver from the
ClearCube web site at http://support.clearcube.com/. Do not use drivers
downloaded directly from the NVIDIA web site, as they have not been validated to
work properly with a ClearCube system.

CMOS Settings

ClearCube PC blades use the Phoenix BIOS. To change BIOS/CMOS settings, press
the F2 key when the ClearCube splash screen appears while booting to access the
utility.
From this utility you can configure items including boot sequence, hard drive settings,
power-up defaults, and power management settings. Note that you do not have to go
into the CMOS setup utility in order to select the boot device. Follow the onscreen
instructions as the blade boots. If booting from a USB CD-ROM device, select
CDROM (do not select removable device).
ClearCube PC blades uses a lithium coin-cell battery for backing up parameter
memory. When you change this battery, remove the old battery and wait at least 30
seconds before inserting the new battery. Otherwise, memory corruption may occur,
and may require sending the blade back to ClearCube for repair.
RAID Settings on the R2200
When equipped with two hard drives, the R2200 blade is capable of RAID settings 0
and 1, configurable from system setup.
RAID 0
RAID 0 implements a striped disk array. Data is broken down into blocks and each
block is written to a separate disk drive. Since no redundant information is stored,
performance is very good, but the failure of any disk in the array results in complete
data loss. RAID 0 is only used to increase disk performance.
RAID 1
RAID 1 implements mirroring. This redundancy of data means that no rebuild is
necessary in case of a disk failure, only a copy to the replacement disk.
