Intel Matrix Storage Manager. The Intel® Matrix Storage technology supported by
the ICH7R chip allows you to create a RAID 0 and a RAID 1 set using only two
identical hard disk drives. The Intel® Matrix Storage technology creates two
partitions on each hard disk drive to create a virtual RAID 0 and RAID 1 sets. This
technology also allows you to change the hard disk drive partition size without
losing any data.

3.5 WDT Function
The working algorithm of the WDT function can be simply described as a counting
process. The Time-Out Interval can be set through software programming. The
availability of the time-out interval settings by software or hardware varies from
boards to boards.
RUBY-9715VG2A allows users control WDT through dynamic software
programming. The WDT starts counting when it is activated. It sends out a signal to
system reset or to non-maskable interrupt (NMI), when time-out interval ends. To
prevent the time-out interval from running out, a re-trigger signal will need to be
sent before the counting reaches its end. This action will restart the counting process.
A well-written WDT program should keep the counting process running under
normal condition. WDT should never generate a system reset or NMI signal unless
the system runs into troubles.
The related Control Registers of WDT are all included in the following sample
program that is written in C language. User can fill a non-zero value into the Time-
out Value
Register to enable/refresh WDT. System will be reset after the Time-out
Value to be counted down to zero. Or user can directly fill a zero value into Time-out
Value Register to disable WDT immediately. To ensure a successful accessing to the
