CHAPTER 4: Software Setup and Operation

The options are as follows:

•POLLING—A PC may use either IRQ-7 or IRQ-5 for handling the parallel port communications. If you need to work without interrupts (usually only with test evaluations), delete the semicolon in this line. This will force the driver to operate in a polled mode without using hardware interrupts.

•UNIDIR—Whenever the SETNDIS driver is loaded into memory, it tests the parallel port to determine whether it can be operated in the faster bidirectional mode. The adapter is then configured according to the test results. However, when you use a long extension cable, the bidirectional mode may not operate reliably, even if the test passes. In this case, you should force the unidirectional mode by deleting the semicolon in this line.

•LPTn—The NDIS driver for the Adapter is auto-configuring, automatically detecting the correct port to be used. To specify the exact parallel port with which the SETNDIS driver is to work, delete the semicolon in this line and specify the port number (1 to 4) in place of the n.

Once you have made your changes, run the SETUP program again, as described in Section 4.3.1.

4.4Microsoft Windows for Workgroups

4.4.1INSTALLATION

The following procedure outlines the installation of the SETNDIS driver software with a new installation of Windows for Workgroups.

1.Start the installation of Windows for Workgroups as described in the “Windows for Workgroups Installation Guide.” Follow the procedure until you reach the window “Network Setup.”

2.In the window “Install Network Adapter,” insert the Network Drivers diskette into the disk drive. Select “Unlisted or Updated Network Adapter” and choose “Continue.” Enter the appropriate path (for example, A:\ or B:\). Then choose “OK.”

3.The “Modular Parallel Adapter” option should display. Choose “OK.”

4.The next window displays Interrupt, Base I/O and Base Memory Address settings that should be “Automatic or Unused.” Choose “OK.”

5.In the window “Network Adapters,” choose “OK.”

6.Windows for Workgroups now modifies your AUTOEXEC.BAT, CONFIG.SYS and PROTOCOL.INI files and changes the extensions of the previous versions to .00x. Choose “OK.”
