System Memory
System Memory indicates the entire amount of installed memory detected in your system, except for memory on Expanded Memory
Specification (EMS) expansion cards. After adding memory, check this category to confirm that the new memory is installed
correctly and is recognized by the system.
Video Memory
Video Memory displays the amount of video memory detected in your system.
Reserved Memory
Reserved Memory allows you to designate a region of system board memory that can be supplied by an expansion card. You
should not enable the reserved memory feature unless you are using an expansion card that requires special addressing.
For example, you may have a memory expansion card that needs to be addressed starting at 15 MB. Selecting the 15M - 16M
option in the Reserved Memory category specifies that the base memory from 15 to 16 MB come from the memory expansion card
(the base memory below the 15-MB address comes from the dual in-line memory modules [DIMMs] on the system board).
The Reserved Memory category has the following options:
None Reserved (the default option)
512KB - 640KB
15MB - 16MB
CPU Speed
CPU Speed indicates the processor speed at which your system boots.
Press the left- or right-arrow key to toggle the CPU Speed category between the resident microprocessor's rated speed (the
default setting) and a lower compatibility speed, which lets you accommodate speed-sensitive applications. A change to this
category takes effect immediately (rebooting the system is not required).
To toggle between the rated processor speed and the compatibility speed while the system is running in real mode, press
Integrated Devices
Integrated Devices configures the devices integrated into the system board. Press
Sound
Sound determines whether the integrated audio controller is On or Off.
Network Interface Controller
Network Interface Controller determines whether the integrated NIC is On, Off, or On with PXE. The default is On with PXE, which
means that the NIC is enabled but not set to boot the system remotely from a network server.
