I have now successfully gone through the process of making a new bootable CD using the ATA_HT1000 patched kernel. I have already done a minimal installation of FreeBSD-7.1-BETA onto the SC1435 PowerEdge box using this CD (BTW dmesg now shows the ad4 disk being recognized as SATA150 instead of giving a warning about a bad cable and recognizing it as an ATA drive). But I'm stuck at the last step ... > Just be sure that once you've installed the box, > you copy the updated kernel onto the box somehow before you > reboot from the > installer (you can use the fixit shell to help with this). I'm at the holographic emergency shell, and df(1) shows all the partitions in ad4s1 mounted under /mnt. So my idea is to cp boot/kernel/kernel /mnt/boot/kernel/ but when I do an ls(1) the /mnt directory appears to be empty ... However I'm unable to umount it! My recollection: $ df -h /dev/ad4s1a => /mnt /dev/ad4s1d => /mnt/tmp /dev/ad4s1e => /mnt/usr ... $ ls /mnt/boot boot: no such file or directory $ ls /mnt/ . .. $ umount /mnt device is busy I'm now downloading a 7.1-BETA-livefs ISO and I'll try next to boot the box with this CD to see if I can scp the kernel from another box ... but any other tip or suggestion is welcome.
