I'm currently running FreeBSD 2.1R on several machines; the most common HD is a 1.2 GB Western Digital Caviar series (but this holds true for other drives and sizes as well). I have discovered that for each installation the default assumed drive geometry is actually the LBA model. Even if I force it back to the physical drive geometry, Boot Manager will not start FreeBSD if LBA mode is disabled in the BIOS. It makes no difference that the geometry specified in the BIOS itself is "normal," not LBA and not "large." You might get the same results if you just enable LBA mode, without specifying it for the drive. -- Ken Are you interested in | byte-sized education | http://www.play-hookey.com over the Internet? |
