Some time ago I posted this message on the bug list regarding installation problems with FreeBSD 5.4 and Fujitsu RX300. I've got a workaround. I'm basically reconfirming the info in the post below, EXCEPT that with FreeBSD5.4, recompiling the kernel with the SMP option actually works. (Recompiling it in 5.3 obviously doesn't fix it, according to the post below) http://lists.freebsd.org/pipermail/freebsd-current/2004-December/043921.html Apparently this "ATAPI_IDENTIFY timed out" error is caused due to the GENERIC kernel that comes on the FreeBSD 5.4 RELEASE ISOs. The GENERIC kernel won't work when there are two CPUs enabled on the motherboard. Fortunately a FreeBSD5.4 SMP kernel WILL work with this hardware, just not the GENERIC kernel on the ISO. So this bug is actually related to SMP and the GENERIC kernel, and NOT any of the drives, RAID or otherwise, on the system (as I thought it might have been earlier, according to the kernel errors I saw). To workaround this and install FreeBSD5.4 on a Fujitsu RX300, one of the CPUs has to be disabled in the BIOS first. Then you should be able to install FreeBSD 5.4 from the CD ISO without any problems. After installation, the kernel has to be recompiled with SMP options. Once the new kernel has been installed, you can reboot the machine and re-enable the switched out CPU in the BIOS. Then you should have a fully working FreeBSD 5.4 with an SMP kernel :) Cheers, Nathan
