MEMORY HOLE AT 15M-16M:
You can reserve this area of system memory for ISA adapter ROM. When
this area is reserved, it cannot be cached. The user information of
peripherals that need to use this area of system memory usually discusses their
memory requirements.
DELAYED TRANSACTION:
The chipset has an embedded 32-bit posted write buffer to support delay
transactions cycles. Select Enabled to support compliance with PCI
specification version 2.1.
AGP APERTURE SIZE:
This field determines the effective size of the Graphic Aperture used for a
particular GMCH configuration. It can be updated by the GMCH-specific
BIOS configuration sequence before the PCI standard bus enumeration
sequence takes place. If it is not updated then a default value will select an
aperture of maximum size.
