ICH Delayed Transaction
Select Disabled to set the South Bridge P2P Bridge Secondary Discard Timer
to 32 micro-seconds for the PCI 32-bit bus. Select Enabled to set the South
Bridge P2P Bridge Secondary Discard Timer to 4 micro-seconds for the PCI
32-bit bus.
ICH DCB
Select Enabled to activate the ICH DMA Collection Buffer to provide Type-F
DMA performance for all DMA channels, allowing the DMA controllers located
in the FPGA to move data between the CPU memory and the coprocessor. It
is ideal for systems whose CPU main memory can be directly accessed from
the FPGA.
