Power button as reset switch
The power button acts as a reset switch when pressed for
more than 4 seconds. This resets the system (regardless
of the microcode status) and forces the power off. Use this
only when power is not completely off or the microcode is
in a hung state.
Running a low-level format
Attention: Make sure the drive address to be formatted is
correct. This procedure erases all information on the disk.
To format the hard disk, use the Full Erase Hard Drive or
Quick Erase Hard Drive in Utility of the PC-Doctor DOS
program. Refer to “Testing the computer” on page 28.

Passwords
When the power-on password (POP), hard disk password
(HDP), and setup password (SUP) (the same function as
supervisor password) are used, the following situations
may occur:
If the POP is the same as the HDP, the POP
prompt appears, but the HDP prompt does not
appear.
If the POP is not the same as the HDP, both
prompts appear.
Hard disk password:
Hard disk password is a
security feature that is used to protect the hard disk data
from unauthorized access. No overriding capability is pro-
vided, so it can not be replaced if it is forgotten. If the cus-
tomer forgets the hard disk password, the hard disk drive
must be replaced.
