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.
4 Re-Configure 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 first booting.
5 Upgrade your system BIOS. New computers may have a newer BIOS
available. When installing a new system BIOS:
# Make sure the BIOS Installed O/S setting is set correctly. This
determines what software will configure all the VXI
plug&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, the BIOS will not perform
this task and will leave it to the O/S to do this. If the
Installed
O/S
is set to Windows NT, NOT PnP O/S, or Other, the BIOS will
perform this task and the system may not work properly.
# For NT version 4.0 or earlier, the BIOS must perform this task
as the O/S does not know how to do this. For Windows 9x,
either the BIOS or the O/S can do this task, so try both. If you
are running Windows NT, set to
Running Windows NT, Not
VXI
plug&play OS or Other.
Set 82350 Read/
Write Performance
Mode
The 82350 card read and write calls use one of two modes:
# Polling. Bytes are transferred to/from the card, one at a time.
Polling mode is advantageous for transferring a small number
of bytes because the setup overhead is very low, but it does
require CPU involvement for each byte transferred.
