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-Agilent PCI cards do not
work properly when sharing IRQ line.
To validate the driver of the 82350B 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 82350B card and check that all other
cards on the same IRQ have a valid driver, not the big yellow
question mark.
When the IRQ is asserted, the OS calls each ISR in turn until
one of them returns TRUE (meaning that it handled the
interrupt). The ISR’s responsibility is to correctly return
TRUE if its device was interrupting or FALSE if not. Drivers
that return TRUE, even though they did not service the inter-
rupt, will cause problems.
To perform driver workarounds, you can upgrade the drivers
for devices sharing an IRQ with Agilent, including, but not
limited to, your video drivers, your LAN drivers, Agilent IDE
and/or SCSI drivers, and your sound drivers
3 Reconfigure your PC. Configure your PC so as to not share
IRQ lines. Many PCI cards have bugs when sharing IRQ
lines. You may or may not be able to do this on all PCs. Many
PCs can be configured using the setup option when the PC
is booting
