DOCUMENT:Q93583 29-OCT-1999 [win3x] TITLE :Unable to Connect to a Server Using Thomas Conrad TC6242 Card PRODUCT :Microsoft Windows 3.x Retail Product PROD/VER:WINDOWS:3.1,3.11 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows for Workgroups versions 3.1, 3.11 ------------------------------------------------------------------------------- SYMPTOMS ======== If you use a Thomas Conrad TC6242 network adapter card with Windows for Workgroups, you must set the card for enhanced mode. If the card is set for compatible mode, you cannot connect to resources from Microsoft MS-DOS. If you try to connect to a server from Windows, you receive the following error message: Unable to read from drive where "x" is the drive letter of the server to which you are trying to connect. WORKAROUND ========== To correct this problem, set the jumper on the TC6242 card to enhanced mode by setting the eighth pin on switch block sw1 to the down position (On). MORE INFORMATION ================ Enhanced Mode ------------- Enhanced mode should be used when you want to optimize communication performance and minimize memory address conflicts with other hardware. This mode is also designed for the Thomas Conrad accelerated drivers, which feature expanded memory addressing options and faster data transfer. In enhanced mode, the adapter's base I/O address is memory mapped. Enhanced mode is the default setting for this card. Compatible Mode --------------- Compatible mode should be used when you are using third-party drivers. This mode operates with any Novell RX-Net-compatible driver or the Thomas Conrad GXL/ARC driver (a global, high performance network shell driver for ArcNet adapters). In this mode, the adapter's I/O address must be manually set on switch block sw3.
