Using the System Setup Program 2-11
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.

Setup Password has a password assigned and Password Status is Locked, the sys-
tem password cannot be changed through the System
Password option and cannot
