1. After inserting the card into your PCI slot, boot your machine to linux and execute
the following command to list the devices detected by the PCI bus:
# lspci -vn
Confirm the output lists a device with Allo.com’s PCI vendor ID which is “d44d”.
The output will be similar to the following:
02:00.0 Bridge: PLX Technology, Inc. Unknown device d44d (rev 01)
Subsystem: PLX Technology, Inc. Unknown device 9030
Note: The output of lspci may or may not state “Allo.com”. If it does not, this does
not indicate a problem and the device ID may change based on latest chip.
The Allo.com card identifier should be listed. If a card identifier is not listed, then
your machine is not PCI 2.2 (or higher), and the card will not work.
