Adding a Suboptimal Logical Configuration Section

To add a second logical configuration section to the INF file XSCSI.INF

1. Right-click on the Log Config Sections folder and select the New Logical Configuration Section option from the popup menu. A new subfolder will be displayed with no section name (the displayed section name will be <Section name>.
2. Double-click on the new folder to display the items you can edit.

You are given the opportunity to edit two items: Section Name and Priority.

• Double-click on the item name Section Name in the edit area to display an Edit String dialog. You can name the new logical configuration section anything; for this example the self-documenting section name "CX2590_NoDMA" was entered in the dialog box.
• Since the board will run without a DMA channel, but sub optimally relative to when it runs with a DMA channel, set the Priority item value to SUBOPTIMAL. Double-click on the Priority item label in the edit area and select the value SUBOPTIMAL from the dropdown list in the Edit List dialog box.

To enter the IO port and IRQ requirements, right-click on the subfolder you just named and follow the same procedures as shown in the earlier topics Adding the I/O Description Item and Adding the IRQ Description Item.

Note that you will not add a DMA description item to this logical configuration section because it describes the device configuration where the device is running sub optimally, without a DMA channel.
