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 built-in 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 chan-
nel, IRQ15 is also used.
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 controls the operation of the system's built-in diskette drive controller.
With Auto (the default) selected, the system turns off the built-in diskette drive con-
troller as 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 Write-Protect is selected, the Auto setting is also in effect (the system
turns off the built-in diskette drive controller as necessary).
Selecting Off turns off the built-in diskette drive controller; this setting is used prima-
rily for troubleshooting purposes.
Speaker determines whether system sounds (other than beep codes) are emitted by
the on-board speaker. A change takes effect immediately (rebooting the system is not
required).
However, even with Speaker set to Off, sounds from the integrated audio controller
will be emitted by the on-board speaker. To disable the on-board speaker completely,
follow these steps:
SCSI controls the system's built-in SCSI controllers. The settings for SCSI are:
Off (the default)
Secondary Only
