Hello -- I just bought a Logitech bus mouse for use with my XENIX system and I am having trouble with the device driver initialization. The driver does not usually show up at system boot-up right after power-on, but it *does* show itself if I boot DOS first. My system configuration is: - One serial port adaptor at COM1 - Logitech bus mouse at COM2 (interrupt vector 3, I/O base addres 023CH, as recommended by Logitech installation manual). - Two parallel ports Anyone have any ideas?

I have a Logitech HiRes Bus mouse on interrupt 5 (I have only one paralell port) and I have the same problem. The XENIX kernel sometimes does not recognize the bus mouse during startup from time to time, which makes the mouse inaccessable. I assume this is a bug in the kernel's init code, which makes the kernel unable to find the mouse if the mouse is not exacty in the mode it expects. I've solved it this way: If I boot XENIX and the mouse does not appear in the device list, then I reboot the machine, start up DOS and run mouse.com. After this I reboot the machine again, this time starting XENIX, and if I'm careful *not* to touch the mouse until after the kernel has started, XENIX will always find the bus mouse. It's a silly bug, but then again.... XENIX is full of them :-( Inge (BoB) { ingea@ifi.uio.no } ========================================================================= == Inge Arnesen, University of Oslo, Norway. == == ==
