Blank Corner
Notch
IMPORTANT: you must set jumpers JP4 and JP5 to correct CPU Voltage.
1)
Turn off your system and disconnect the power source.
2)
Remove the existing CPU from the ZIF socket by pulling the ZIF lever upwards at a 90
degree angle.
3)
Insert the CPU with the correct orientation as shown below. Use the notched (white dot)
corner of the CPU as your guide. The notch in the corner of the CPU should correspond
with PIN 1 of the ZIF socket (Notice: Pin 1 is the blank corner of the ZIF socket with
one hole missing).
4)
Once the CPU is inserted close the socket’s lever.
WARNING: Without a fan, the CPU can overheat and will cause damage to both the CPU
and the FR550 mainboard.

ISA & PCI Slots
There are two types of ISA expansion cards, design-Legacy and PnP (Plug & Play). For
Legacy cards you must set the cards’ jumpers manually. For Plug & Play cards, your system
will adjust the IRQs automatically. You can verify the IRQ allocation either by using
Microsoft’s Diagnostic (MSD.EXE) utility which is in the Windows directory or through the
Windows 95 resources menu.
