Last Revised AST RESEARCH, INC. TECHNICAL BULLETIN # 1739 07/01/97 TITLE: Ascentia J40 and Xircom PC Cards ISSUE When the user runs a Xircom installation on an Ascentia J40 system that is running in the DOS or Windows 3.1x operating system, the software may report that there is no available IRQ for the device. This issue affects all Ascentia J40 systems. BACKGROUND The Plug-and-Play (PnP) BIOS in the Ascentia J40 masks all unused IRQs at the interrupt controller. The Xircom drivers assume that if an IRQ is masked ON, it is in use. ACTION To correct this issue, perform the following: 1. Download the file IRQ10OFF.COM from one of AST's On-Line! services as follows: AST WWW Site: http://www.ast.com AST On-Line!

Edit the AUTOEXEC.BAT file. The first line of the AUTOEXEC.BAT file should read: C:\IRQ10OFF.COM 4. Reboot the system. The Xircom PC card should now be configured to use IRQ 10. For instructions on configuring your Xircom PC card, please refer to the user documentation included with the card, or contact Xircom Technical Support at (805) 376-9200 for assistance.
