You didn't say that! ;-) The driver has changed considerably since then. I would highly suggest that you pick up a 2.0-950210-SNAP floppy with an updated kernel on it. You can get it as: ftp.cdrom.com:/pub/FreeBSD/2.0-950210-SNAP/floppies/cpio.flp cpio.flp is a tar-gzipped file that has many files in it besides just the kernel. It may actually be best to get the two floppies (boot.flp.gz and cpio.flp) and install the mini system from them. The only problem is that some of the networking utilities from 2.0R are not compatiple with 2.0-SNAP, so you may need to upgrade other peices of the system. If you can get the system up to the point that you can compile a new kernel, it should be easy to compile in the newer aic7xxx driver. > >After this happens the system hangs BIG TIME.

I'm guessing you have external devices you didn't power cycle which is why you got stuck. >I can exit to the shell and everything looks ok.

The newer driver does some things to make it more tolerant of this issue, but you should try to shorten your externel cabel lengths and make sure you have active terminators on all cabel ends. > >I tried turning off all BIOS shadowing and caching, same result.
