Resource Allocation. Part IV

VGA Share Memory Size (Frame Buffer Size)

This parameter allows setting a size of operating memory which will be allocated for operation of integrated video adapter.

Possible values: 8M, 16M, 32M, 64M, 128M, 256M, 512M – a size of allocated memory in Mbytes. The amount of memory available for operating system and some applications will be decreased by appropriate value.

PCI Latency Timer

This parameter sets the time delay when the control over PCI-bus is transmitted from one device which operates in Bus Master Mode to another.

Possible values – 32, 64, 96, 128, 160, 192, 224, 248. The values 32 or 64 are set by default. As a rule, such value corresponds to maximum system capacity.

PCI/VGA Palette Snoop (Palette Snooping)

This parameter sets a special mode that corrects VGA palette using additional video devices, for example MPEG-encoder.

If there are some problems with operation of such devices, set the value “Enabled (On)” and for all other cases select “Disabled (Off).

Maximum Payload Size

Some motherboards with PCI Express-bus have got such parameter. It sets a maximum size of data package transmitted via this bus.

Possible values – 128, 256, 512, 1024, 2048, 4096. They define a maximum size of data package in bytes. A value 4096 is set by default; it should not be changed without any necessity while ensuring the maximum capacity of PCI Express.
