Good day, I posted a question last week on my inability to get FreeBSD installed on a machine with a Mylex DAC960PTL1 RAID array. I had originally attributed the problem to a bug mentioned on the 5.0 release errata page which describes my condition, but after further testing I am not so sure anymore. The machine in question is a NEC, dual 733MZ P3 with a Mylex DAC960 RAID controller. I'm performing the install via floppy/FTP. Immediately prior to the installation, the machine was running Red Hat Linux 7.2 , occupying the entire disk array, and functioning great. That installation has since been deleted, as I've attempted to install FreeBSD using the entire disk array. The installation proceeds fine, but the machine hangs upon reboot at the boot manager prompt. If I try again and install the default boot loader instead of the boot manager, I get "Missing Operating System". I've so far tried 5.0-RELEASE, 4.8-RC2 and 4.7-RELEASE (using their respective installation floppies) with identical results. These symptoms match exactly installation FAQ entries 3.21 and 3.22 . However, the former suggests to resolve a conflict between two operating systems conflicting over disk geometry, and I only have FreeBSD installed, using the entire disk array. The latter FAQ suggests the problem is with the BIOS not detecting the disk properly. However, I am really not sure what I need to do here, since I know the BIOS/controller are able to work with large partition sizes due to the previous success with Red Hat. The only difference, of course, is that the Linux installation had several partitions while FreeBSD uses the single partition with slices. Lastly, I am not even positive that FreeBSD supports booting from this drive. The card initially identifies itself as a "DAC960PTL1" in the name, which doesn't exactly match any of the DAC960 cards listed on the hardware page. FreeBSD is able to ID and work with the drive, etc. when the mlx driver module is loaded, so I would guess that this isn't a problem. I'm at a loss as to what I can do. Sorry for making this message so large, but I wanted to be comprehensive.
