Diskette Interface; Pc Speaker; Video Dac Snoop; System Security - Dell OptiPlex E1 Reference And Installation Manual

With Auto (the default option) selected, the system turns off the built-in EIDE inter-
face when necessary to accommodate a controller card installed in an expansion slot.
As part of the boot routine, the system first checks for a primary hard-disk drive con-
troller card installed in an expansion slot. If no card is found, the system enables the
built-in EIDE interface to use IRQ14 and IRQ15.
If a primary controller is detected on the expansion bus, the built-in EIDE interface is
disabled.
Selecting Off disables the built-in EIDE interface.
Diskette Interface controls the operation of the system's built-in diskette drive
controller.
With Auto (the default option) selected, the system turns off the built-in diskette drive
controller when necessary to accommodate a controller card installed in an expansion
slot.
With Write Protect selected, nothing can be written to diskette drives and tape drives
using the system's built-in diskette drive controller. (The system can still read from the
drives.) When this option is selected, the Auto option (whereby the system turns off
the built-in diskette drive controller as necessary) is also in effect.
Selecting Off turns off the built-in diskette/tape drive controller; this option is used pri-
marily for troubleshooting purposes.
PC Speaker determines whether the on-board speaker is On (the default) or Off. A
change to this category takes effect immediately (rebooting the system is not
required).
Video DAC Snoop lets you correct video problems that may occur when certain video
expansion cards are used. The default is Off. If you are using a video card and prob-
lems such as incorrect colors or blank windows occur, set Video DAC Snoop to On.

characters.
