When enabled, accesses to the system BIOS ROM addressed at
F0000H-FFFFFH are cached, provided that the cache controller is
enabled.
As with caching the System BIOS above, enabling the Video BIOS
cache will cause access to video BIOS addressed at C0000H to
C7FFFH to be cached, if the cache controller is also enabled.
In order to improve performance, certain space in memory can be
reserved for ISA cards. The memory must be mapped into the memory
space below 16 MB.
This item allows you to set the Enabled or Disabled Ethernet Boot
ROM function.
