82350 PCI GPIB card Troubleshooting Guide

If I/O Config reports finding an 82350 card with serial number ffffffff:

This is typically caused by getting into a situation where nothing is properly configuring PCI cards. Try the following:
- Windows NT: Make sure that the BIOS "Operating System" setting is set to "Not PnP OS" or "Running Windows NT" or "Other". It should not be set to "Running Windows 95", "Running Windows 98", "Running Windows 2000", or "PnP O/S"
- Upgrade your system BIOS to the latest version. Note that even brand new computers tend to have new BIOS's available!

If your computer locks up or freezes after installing:

What we're seeing is mostly interrupt conflicts with other drivers in the system. PCI allows sharing of IRQ's, but this also means that the drivers for cards with which we are sharing an IRQ must be handling interrupt chaining properly. Both NT and Windows 9x allow multiple drivers to install interrupt service routine's (ISR's) for a single IRQ. The OS will keep a list of all the ISR's installed for each IRQ. When the IRQ is asserted, the OS will call 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. Here are some ways to work around drivers that are not behaving properly:
- Upgrade the drivers for devices sharing an IRQ with us, including but not limited to:
  - Your video drivers
  - Your LAN drivers
  - Your IDE and/or SCSI drivers
  - Your Sound drivers
- Try to force our driver to be installed earlier in the ISR chain
  - Windows NT: Run Control Panel, Devices. Select the HP350i32. Select "Startup...". Set to "System" instead of the default "Automatic". Warning: running I/O Config will set this back to Automatic!
  - Windows 9x: Change your BIOS "Installed OS" setting. Try all the different values and use the one that works.
- Windows 9x: Make sure that all devices sharing an IRQ with our card have drivers installed. Right-click on "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, and not the big yellow question-mark.
- 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 PC's, many can be configured using the setup option when the PC is first booting.
Upgrade your system BIOS (NOTE: even new computers may have a newer BIOS available!)
Make sure the BIOS "Installed O/S" setting is set correctly. This determines what software will configure all the Plug-n-Play cards in your system. Either the BIOS or the O/S 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. If the BIOS "Installed O/S" is set to "Windows 95", "Windows 98", "Windows 2000" or "Running a PnP O/S", then the BIOS will not perform this task and leave it up to the O/S to do this. If the "Installed O/S" is set to "Windows NT", "NOT PnP O/S", or "Other", then the BIOS will perform this task. Note that for NT version 4.0 or earlier, the BIOS must perform this task, as the O/S doesn't know how to do that. For Windows 9x, either the BIOS or the O/S can do this, so try both!
- If you are running Windows 95, try all combinations of settings
- If you are running Windows NT, set to either Running Windows NT or Not Plug&Play OS or Other,
