Chipset Configuration submenu

The Chipset Configuration submenu allows you to set advanced chipset options.
Setting the wrong values in the items below might cause the unit to malfunction.
Meaning
This item allows you to enable or disable virtual machines (running within the operating system of your
Matrox 4Sight GPm) to have full access to all the peripheral devices connected to your Matrox 4Sight GPm.
This item allows you to enable or disable the remapping of interrupts so that a virtual machine has full access
to the interrupt requests generated by its connected I/O devices.
This item allows you to enable or disable the virtual machine's direct-memory access (DMA) requests.
This item allows you to set the operating speed of the DDR3 memory modules, in MHz.
If a fixed speed is set and the memory module or the processor does not support this speed, your unit might
be unusable or might not function reliably.
For Matrox 4Sight GPm, it is strongly recommended that you set this item to Auto (default).
❖
This item allows you to select the unit's response when power is re-applied to the unit after a power loss (for
example, an unplugged power cable).
By selecting S5, the unit will stay powered off when power is re-applied after a power failure.
By selecting S0, the unit will power on when power is re-applied after a power failure.
By selecting Last state, the unit will return to its last state when power is re-applied after a power failure. If
power had been on before the power failure, the unit will power on. If power had been off before the power
failure, the unit will stay powered off.
