conflicts with other drivers in the system. PCI allows sharing of IRQs, but this also means the drivers for cards which share an IRQ must handle interrupt chaining properly. Both Windows NT and Windows 98 allow multiple drivers to install interrupt service routines (ISRs) for a single IRQ. The operating system (OS) keeps a list of all the ISRs installed for each IRQ.

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 interrupt, will cause problems. Try the following steps to perform driver workarounds:

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.

For Windows 98SE, change your BIOS Installed OS setting.

Try all the different values and use the one that works. Make sure all devices sharing an IRQ with your 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.

4Reconfigure 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
