However, I have a much better Adaptec 2940UW adapter card installed, so the AMD controller has nothing attached to it and I have it disabled in the BIOS. Until this weekend, I was using FreeBSD 2.2-current circa Aug 96. It used to print "pci0:9 ... AMD ... [no driver assigned]", then it would find the ahc0 driver and all would be well. After a cvsup to tag=RELENG_2_2 this weekend, I noticed that there is a new driver amd0 which is listed first in the default kernel config. file. Booting with this driver installed in that order results in dropping into the debugger. (I can produce the exact output if someone wants it.) To fix this for me, I just disabled amd0 and rebuilt my kernel, so I'm OK now. But I wanted to flag this for someone's attention, so that others would be able to use FreeBSD-2.2 out of the box without a kernel recompile. (To wit, how do you do a kernel recompile when you can't boot/install off the floppy?) Thanks! -- Brent J. Nordquist bjn@visi.com +1 612 827-2747
