The +5 V and +12 V operating voltages are monitored for overvoltage
and undervoltage conditions. The detection of a faulty voltage causes
the PC power supply to switch off immediately. –12 V potential is not
monitored.
Installation
L
Connect the ”Floppy A boot drive” connection end of the ribbon cable to the
floppy disk drive. Connect the other end of the cable to the X75 floppy disk
connector. On the ribbon cable, observe the red marking of the no. 1 conduc-
tor which must always be connected to PIN 1 of the connected devices.
In most cases, notched connectors will provide for connections with proper
conductor alignment.
L
The power supply for the floppy disk drive must also be connected. This is
accomplished by connecting the connecting cable on the floppy disk drive
(4–pin plug connector) to the X76 power supply connector.
L
If the system does not recognize the floppy disk drive, the latter must be acti-
vated in the ”I/O Device Configuration” BIOS submenu by changing from
”Disabled” to ”AUTO” or ”Enabled”. If necessary, the floppy disk type must
also be selected under ”
Diskette 1
” in the main menu.
In order to start the BIOS setup function, press <F2> when the ”Press <F2>
to enter Setup” display appears during booting. Then the BIOS main menu
will be displayed. Make the above mentioned settings. Leave BIOS via the
”Exit Saving Changes” entry in the Exit menu.
To do so, press the <Z> key if you have a keyboard with a German layout (Z =
Y for Yes).
