related items manually. Setting options: [Manual], [Auto By SPD], [Turbo], [Ultra].
Memory Hole
In order to improve performance, certain space in memory can be reserved for ISA
peripherals. This memory must be mapped into the memory space below 16MB. When
this area is reserved, it cannot be cached. Settings: [Disabled], [15MB-16MB].

The field specifies the size of system memory allocated for video memory. Setting
options: [Disabled], [Enabled, 1MB], [Enabled, 8MB].

This setting controls just how much system RAM can be allocated to IGD (internal
graphic display) for video purposes. The aperture is a portion of the PCI memory
address range dedicated to graphics memory address space. Host cycles that hit the
aperture range are forwarded to the IGD without any translation. The option allows
the selection of an aperture size of [128MB], and [256 MB].
