Memory Hole at 15MB - 16MB
In order to improve performance, certain space in memory can be
reserved for ISA cards. This field allows you to reserve 15MB to 16MB
memory address space to ISA expansion cards. This makes memory
from 15MB and up unavailable to the system. Expansion cards can
only access memory up to 16MB. The default of this field is set to
Disabled.
The choice: Enabled, Disabled.
AGP Aperture Size (MB)
Select the size of Accelerated Graphics Port (AGP) aperture. The
aperture is a portion of the PCI memory address range dedicated for
graphics memory address space. Host cycles that hit the aperture range
are forwarded to the AGP without any translation.
The choice: 4M, 8M, 16M, 32M, 64M, 128M, 256M.
