I have a Pentium 133 SCSI motherboard with a PS/2 AUX port onboard. Just to see if it was just Windows 95 doing some magic to find the mouse port, I used my Linux boot disk from another machine I have (which also has a PS/2 AUX mouse port), and it detected and installed the PS/2 mouse driver. So it was the FreeBSD PSM probe code-- so I commented out the actual test after the read of the DATA port in psmprobe(), and booted with my new kernel, and it loaded the driver and it worked fine with XFree86. This seems to say the probe code is wrong (maybe it just happens to work on some machines or maybe mine is slightly different). Since Linux got it correct, I check how they detected the PS/2 mouse, and they use an INT 11 to read the configuration and then check bit 2 (0x04) from the INT return value. FreeBSD seems to be trying to do some kind of handshake on the CNTRL port and then reading the DATA port. > Soren Schmidt (sos@FreeBSD.org) FreeBSD Core Team-- Brett Bourbin, President SELGUS LIMITED brett@selgus.com 555 Bryant Street, Suite 221 Palo Alto, CA 94301
