 * Microsoft Windows 95

SYMPTOMS
When you are using a DCA IRMAtrac Convertible Token Ring network adapter in ISA mode, you may receive the following error message when you use the NET START command:

Invalid entry for DMAChannel in PROTOCOL.INI

This problem occurs only if you are loading real-mode (NDIS 2) drivers for the network adapter.

CAUSE
The network adapter is configured to use DMA channel 3 or 7. Windows 95 does not support the use of DMA channel 3 or 7 with the DCA IRMAtrac Convertible Token Ring network adapter.

RESOLUTION
Configure the network adapter to use DMA channel 5 or 6 in ISA mode. To do so, follow these steps:


 * 1) Use the right mouse button to click My Computer, then click Properties on the menu that appears.
 * 2) Click the Device Manager tab.
 * 3) Click the DCA network adapter, then click Properties. Note that you may have to expand a branch of the hardware tree by double-clicking the branch, or clicking the plus sign (+) to the left of the branch, before you can click the network adapter.
 * 4) Click the Resources tab.
 * 5) Click Direct Memory Access, then click Change Setting.
 * 6) Type the DMA channel you want to use, then click OK.

STATUS
Microsoft has confirmed this to be a problem in Microsoft Windows 95. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
