Read Around Write [Enabled]
Setting this field to [Enabled] allows the memory controller to store write
data in its buffer whenever the CPU issues a write command. The next time
the CPU needs the data, it retrieves the data from the memory buffer without
accessing the SDRAM. Configuration options: [Disabled] [Enabled]
Delayed Transaction [Disabled]
When set to [Enabled], this feature frees the PCI bus when the CPU is
accessing 8-bit ISA cards. This process normally consumes about 50-60
