Cache BIOS
ROM
Enabled
Disabled
Allows to enable or disable a caching request for the computer's
BIOS.
Note: This option allows the computer's BIOS to be cached in the
primary cache and secondary cache (if installed). This increases
computer performance because BIOS instructions are executed in
cache instead of RAM.
Shadow video
ROM
Enabled
Disabled
Enables or disables the computer's shadow video ROM option.
Note: The main logic board reserves an area of DRAM for a copy of
video BIOS ROM. This DRAM called "shadow memory" is write-
protected and has the same addresses as the video BIOS ROM
locations. When the video BIOS ROM is shadowed, the ROM
information is copied into an appropriate area in DRAM. This
increases the computer's performance because the video BIOS
instructions are in fast DRAM instead of ROM.
E00000h
selection
Local memory
AT bus
Allows to select the E00000h - EFFFFFh memory allocation.
Note: This option allows to enable or disable the E00000h to
EFFFFFh DRAM range. When using optional software, such as
frame grabbers and/or certain LAN network expansion boards, it may
be necessary to disable this DRAM range and force it to the ISA bus
to avoid memory conflicts. Refer to the documentation supplied with
the software to see if this memory range is required for proper
operation.
Cache video
ROM
Enabled
Disabled
Enables or disables the computer's cache video ROM option.
This option allows the computer to cache video BIOS information.
Caching the computer's video ROM provides greater performance at
the VGA level, however, when running certain application software,
conflicts might occur.
Shadow 32K
at C8000
(1) (2)
Enabled
Disabled
Enables or disables the computer's C8000 shadow option.
Note: This option allows the computer to shadow any device BIOS
located in the C8000 address space. Shadowing device BIOS in this
area increases the computer's overall performance.
Refer to the device's documentation to determine if this function can
be performed.
Shadow 32K
at D0000
(1) (2)
Enabled
Disabled
Enables or disables the computer's D0000 shadow option.
Note: This option allows the computer to shadow any device BIOS
located in the D0000 address space. Shadowing device BIOS in this
area increases the computer's overall performance.
Refer to the device's documentation to determine if this function can
be performed.
