Chapter 4 Common Configuration Questions
• A network PXE server on the same subnet
• An external USB mass storage device such as a USB hard drive, USB CD/DVD-ROM, or
USB key
• An external USB floppy drive
• Most PCI or PCIe-based devices that provide an Option ROM
Note There are limitations when booting from a USB device. You can install
Windows 7 and later versions from a USB CD/DVD-ROM, but not earlier versions.
PXIe-8840 BIOS configures the USB devices so that they work in a DOS
environment.
How do I configure the controller to boot from these devices?
There are two methods.
• Enter Setup and select the Boot menu. You will see a list of all bootable devices, ordered
by device type. You can set the boot order using <+> and <->. Set the order by device type
and set the order for the devices listed within the device type.
• To boot from a different device without changing the boot order in the BIOS, press <F10>
continuously while booting. After the BIOS completes the POST and just before the
controller boots the OS, the Boot menu is displayed. You can select the device type you
want to boot from.
Cables and Connections
How do I plug both a PS/2 mouse and PS/2 keyboard into the controller?
The PXIe-8840 has no PS/2 connector, and you need to use a USB Y-splitter cable as shown in
Figure 4-1, or a similar device, to connect both a PS/2 mouse and PS/2 keyboard. National
Instruments part number 778713-01 is such a cable and is available through the online catalog
at
ni.com/products.

What if I don’t have a Y-splitter cable? Can I still use a mouse and keyboard?
If you do not have a Y-splitter cable, plug a USB keyboard into any USB connector. You can also
plug a USB mouse into any USB connector.
