2 Troubleshooting Guidelines

be configured using the setup option when the PC is booting.

5Upgrade 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 Plug and Play cards in your system. Either the BIOS or the operating system (OS) 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 Installed O/S is set to Windows NT, NOT PnP O/S, or Other, the BIOS will per- form this task and the system may not work properly

For NT 4.0, the BIOS must perform this task as the OS does not know how to do this. For Windows 98, 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 Plug and 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.

Interrupt. An entire buffer is transferred to/from the card without CPU involvement. Interrupt mode is advantageous for transferring large buffers because the higher per byte transfer rate more than compensates for the relatively long interrupt setup overhead.
