As part of the boot routine, the system first checks for a
primary
hard-disk drive
controller 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.

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
system’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 purpo ses.
