DOCUMENT:Q66789 30-JUL-2001 [lanman] TITLE :Using 3Com EtherLink Plus w/ DOS LAN Man 2.x/Windows 3.x PRODUCT :Microsoft LAN Manager PROD/VER: OPER/SYS: KEYWORDS: ====================================================================== SUMMARY ======= Question: I tried to run Windows version 3.0 or 3.1 in 386 enhanced mode while using a 3Com EtherLink Plus card. Unfortunately, Windows hung and I had to reboot my machine. How can I prevent Windows from hanging? Response: On some systems, the 3Com EtherLink Plus card should not be allowed to control DMA transfers when running Windows version 3.0 or 3.1 in 386 enhanced mode. The following method can be used to disable the card's control of the DMA by adding one of the following lines to the [ELNKPL_NIF] section of the DOS LAN Manager version 2.0 (or later) PROTOCOL.INI file: ; Use this line if the card is in a 16-bit slot. DATATRANSFER = PIO_WORD ; Use this line if the card is in an 8-bit slot. DATATRANSFER = PIO_BYTE Additional query words: 2.00 2.10 2.10a 2.20 3.00 3.10 ====================================================================== Keywords : ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
