DRAM Timing
The DRAM timing is controlled by the DRAM Timing Registers. The
timing type is dependent on the system design. Slower rates may be
required in some system designs to support loose layouts or slower
memory.
System BIOS Cacheable

F0000H-FFFFFH are cached, provided that the cache controller is
enabled.
Video BIOS Cacheable
When enabled, access to video BIOS addressed at C0000H to C7FFFH
are cached, provided that the cache controller is enabled.

Memory Hole at 15M-16M
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. By default, this field is set to
Disabled.
