Cpu Speed; Integrated Devices; Sound; Network Interface Controller - Dell OptiPlex E1 Reference And Installation Manual

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 mem-
ory 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 indicates the processor speed at which your system boots.
Press the left- or right-arrow key to toggle the CPU Speed category between the resi-
dent 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 <Ctrl><Alt><\>. (For keyboards that do not use
American English, press <Ctrl><Alt><#>.)
Integrated Devices configures the devices integrated into the system board. Press
<Enter> to configure these options.
Sound determines whether the integrated audio controller is On or Off.
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.
Mouse Port enables or disables the system's built-in Personal System/2 (PS/2)-
compatible mouse port. Disabling the mouse allows an expansion card to use
interrupt request (IRQ) 12.
For more information about built-in ports, port designations, IRQs, and the remapping
of ports, see "Connecting External Devices" in your online System User's Guide .
