Dealing with Problems (Advanced)
USB floppy disk drives do not work as
a boot drive
Only the Panasonic CF-VFDU03 USB floppy disk drive (optional) can be used.
Do not connect the floppy disk drive to the USB hub.
Make sure [Legacy USB Support] is set to [Enable] in the [Advanced] menu of
the Setup Utility.
If two or more devices are displayed at [Floppy Drive] in the [Boot] menu of the
Setup Utility, make sure the USB floppy disk drive is at the top of the [Boot]
menu (
page 97
)
After powering off the computer, connect the USB floppy disk drive and restart
the computer.
Remove the floppy disk drive that is inserted inside the multimedia pocket or
connected to the parallel port.

Cannot tell whether the RAM module
has been correctly installed
If the RAM module is recognized correctly, the total size of the main unit
memory and RAM module memory is displayed on the [Information] menu of
the Setup Utility (
page 89
).
If the RAM module is not recognized, turn the computer off and reinsert the
RAM module.
The RAM module has not been
recognized
Make sure the RAM module has been properly inserted.
Use the RAM module that supports the recommended specifications (

).
The address map for IRQ, I/O port
address, etc. is unclear
The current address map can be displayed with the following procedure.
[start] - [Control Panel] - [Performance and Maintenance] - [System] -
[Hardware] - [Device Manager] - [View] - [Resources by type].
The device connected to the serial
port does not work
Check the connection.
Confirm that the device driver for the serial port works. Refer to the operating
instructions of the device. Confirm that two mouse devices are not connected,
one through the external keyboard/mouse port of the port replicator and the
other through the serial port.
Try setting [Touch Pad] and [Touchscreen](only for models with touchscreen) to
[Disable] in the Setup Utility.
Confirm that [Serial Port A] (or [Serial Port B]) has not been set to [Disable].
Depending on the device, the operable I/O and IRQ may be limited. Try
different I/O and IRQ settings in the Setup Utility.
