AST RESEARCH, INC. TECHNICAL BULLETIN # 1539 10/01/96 TITLE: PCMCIA, 3Com 3C589B, Ascentia P and J ISSUE The Ascentia P or J systems may not recognize the 3Com 3C589B PC card. The system may hang when "Net Start" is run in the AUTOEXEC.BAT when using Windows 3.1x with NDIS 2 Drivers. BACKGROUND The PCMCIA 3Com 3C589B card needs to be configured with the same settings as referred to in the PROTOCOL.INI file that is located in the Windows directory . The card may also need to be configured using the configuration utility supplied. When using the default installation of a 3Com PCMCIA card, the interrupt setting and the I/O address setting are not added to the PROTOCOL.INI file. ACTION To resolve the issue in the Ascentia P, edit the PROTOCOL.INI file. Before attempting to edit this file it is recommended that a backup copy of the file be made. After doing so, edit the file as follows: [ELPC3] DriverName=ELPC3$ ioaddress=0x300 interrupt=0x3 To resolve the issue in the Ascentia J, edit the PROTOCOL.INI file as follows: [ELPC3] DriverName=ELPC3$ ioaddress=0x300 interrupt=11 NOTES The top settings are the default settings of the 3Com board. To change these settings, the user can run the Install program from the diskette supplied with the 3C589 card. Change the configuration to reflect the changes in the PROTOCOL.INI file. The latest 3C589 configuration utility can be downloaded from the 3COM's web site at http://www.3com.com or ftp.3com.com. The file name is 3C589N.EXE.
