The CDROM never probed before, now it does (at least every time I tried: only about half a dozen reboots for the moment). So there's probably something strange with the probe code and how it interacts with wd[0-3] declarations. So the CDROM now probes correctly, but OTOH I didn't manage to use it. I get the following message every time: bofh /kernel: atapi1.0: controller not ready for cmd The machine then seems to hang, more or less (X11 kindly moves the mouse pointer, but the network is dead). > FreeBSD still has difficulties with some ATAPI CD-ROM drives.

I tried to find out why it worked with a Linux kernel by comparing our IDE code and theirs, but it was way beyond my comprehension. I'm not trained for the black magic of IDE probing. I'll try to investigate some more, then I'll try a bug report. -- Pierre Beyssac pb@enst.fr To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
