Park Fixed Disks
The Park Fixed Disk function prepares the fixed disks for
relocation. The fixed disk heads are placed over the
diagnostics cylinder so that vibrations do not cause errors
on the usable media. The heads are also automatically
parked for safe travel when you turn off the computer or
the computer enters standby mode.
Diagnostics
If you select the Diagnostics Program, a warning and menu
display. Press N to abort Diagnostics. Press Y to continue,
and the Diagnostics menu displays.
Each test listed indicates the hardware item and its
configuration to be tested. Some items are listed only
present (P) or not present (N), while others specify a
hardware type. For example, KEYBOARD can be an 84-key
keyboard, a 101-key keyboard, or not present (N). The
floppy types are defined as they are in the Setup Program
menu.
The Diagnostics menu reflects the hardware configuration
that the Diagnostics Program detects in your computer. The
selection process overrides this automatic selection process
or excludes specific tests from a complete suite of tests to
be performed.
Press the cursor keys to highlight an item you want to test
or change, and press F5 and F6 to select new items in each
field.
You can test a single item by moving the highlight to a
particular test and pressing F10. You must select
something other than not present (N) or NONE.
