Resource Controller By
This BIOS items provides function for configuring all of the boot and Plug & Play
compatible devices. Normally, user should set this items Auto, then the BIOS can
automatically assign the IRQs and DMA channels. All the IRQ and DMA assignment fields
should disappear as a result.
But if you are having problems assigning the resources automatically via the BIOS, you can
select Manual to reveal the IRQ and DMA assignment fields. Then you can assign each IRQ
or DMA channel to either Legacy ISA or PCI/ISA PnP devices.
Options Auto (ESCD), Manual. Default value is Auto (ESCD).
PCI VGA Palette Snoop
This option is only useful if you use an MPEG card or an add-on card that makes use of the
graphics card's Feature Connector. It corrects incorrect color reproduction by "snooping"
into the graphics card's framebuffer memory and modifying (synchronizing) the information
delivered from the graphics card's Feature Connector to the MPEG or add-on card. It will also
solve the problem of display inversion to a black screen after using the MPEG card.
Enabled Enable PCI VGA Palette Snoop.
Disabled Disable this function. (Default value)
Maximum Payloads Size
This option provides function for user to set the maximum TLP payloads size for the PCI
Express devices. The unit is “byte”.
