2 Troubleshooting Guidelines
38 82350B Installation and Configuration Guide
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.
4 Perform Driver Workarounds. Here are some
ways to work around drivers that are not
behaving properly:
a Upgrade the drivers for devices sharing an IRQ
with the 82350, including but not limited to,
your video drivers, your LAN drivers, Agilent
IDE and/or SCSI drivers, and your sound
drivers.
b Try to force the Agilent driver to be installed
earlier in the ISR chain.
c For Windows 98 SE, change your BIOS
Installed OS setting. Try all the different
values and use the one that works.
d For Windows 98 SE, make sure all devices
sharing an IRQ with our card have drivers
installed. Right-click My Computer and select
Properties, then Device Manager. Highlight
Computer and click Properties. Find the
82350 card and check that all other cards on
the same IRQ have a valid driver, not the big
yellow question-mark.
5 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 your PC; many PCs can
be configured using the setup option when the
PC is first booting.
