3-18 Dell Precision 210 Desktop Systems User’s Guide
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 integrated EIDE
interface is enabled and the controller on the master EIDE drive is designated as the
primary controller, using IRQ14. If any EIDE drives are attached to the secondary EIDE
channel, IRQ15 is also used.
If a primary controller is detected on the expansion bus, the integrated EIDE interface
is disabled.
Selecting Off disables the integrated EIDE interface.

Diskette controls the operation of the system’s integrated diskette drive controller.
With Auto (the default) selected, the system turns off the integrated diskette drive
controller as necessary to accommodate a controller card installed in an expansion
slot.
With Write-Protect selected, nothing can be written to diskette drives using the sys-
tem’s integrated diskette drive controller. (The system can still read from the drives.)
When Write-Protect is selected, the Auto setting is also in effect (the system turns
off the integrated diskette drive controller as necessary).
Selecting Off turns off the integrated diskette drive controller; this setting is used
primarily for troubleshooting purposes.

the integrated speaker. A change takes effect immediately (rebooting the system is
not required).

pletely, follow these steps:
1. Start the Windows 95, Windows 98, or Windows NT operating system.
2. Double-click the speaker icon in the right corner of the task bar.
3. From the Master Out panel, select Advanced Controls from the Options menu.
4. Click the Advanced button under the Master Out column.
5. Click the PC Speaker Mute check box.
