This field allows creation of a memory gap (free address space in the system RAM) for
use with an option card. This gap is 128 KB in the conventional memory from 512 KB to
640 KB or 1 MB in extended memory from 15 MB to 16 MB and this requires the use of
conventional or extended memory. The choices are Disabled (default) or Conventional,
and Extended. Security Menu
Use this menu to define system passwords and set other security options. If you set a
password, you must enter it a second time to verify it. Passwords can be used to limit access to the setup menus or prevent unauthorized booting of the unit. This field is inactive until a supervisor password has been set. If the supervisor and
user passwords are set and this option is enabled, you must enter a password (either
one) during the boot sequence. Entering an incorrect password three times in a row
causes the system to shut down. If only the supervisor password is set and this option
is enabled, you must enter the supervisor password during the boot sequence. If no
passwords are set and this option is enabled, nothing happens. The choices are
Disabled (default) and Enabled.
Fixed disk boot sector This field allows protection of the boot sector of the hard disk to protect against
viruses. The options are Normal (unprotected, default) and Write Protect (protected).
Diskette access This field is inactive until a supervisor password has been set. When Supervisor is
selected (default), only the supervisor can access the floppy drive. When User is
selected, anyone can access the floppy drive.

cannot access any fields of the Power or Boot menus in addition to the restrictions
listed in the table above the Security menu diagram on the last page.
