This section provides guidelines for 82351A BIOS/Interrupts
Settings software checks.
If Connection Expert reports finding an 82351A card with
Serial Number ffffffff, this is typically caused by PCIe cards
not properly being configured. Try the following steps. If
these steps do not work, remove and re- install the 82351A
and then reconfigure the card.
1 Upgrade your system BIOS to the latest version. New
computers often have newer BIOSs available. When
installing new BIOS, ensure the BIOS Installed O/S setting
is set correctly. This determines what software will
configure all the Plug and Play cards in your system.
Either the BIOS or the operating system can perform the
task of querying all the cards to determine their resource
needs, picking a valid configuration for all these cards,
and telling the cards what their actual resource
settings are.
2 If your computer locks up or freezes after installing.
Typically, this is caused by interrupt conflicts with other
drivers in the system. Some non- Keysight PCIe cards do
not work properly when sharing IRQ line.
To validate the driver of the 82351A card, go to Device
Manager by selecting Start > Control Panel > System > Hardware
> Device Manager. For Windows 8, right- click the
bottom- left corner of the Desktop and select Device
Manager. Find the 82351A card and check that all other
cards on the same IRQ have a valid driver, not the big
yellow question mark.
