Here is the latest on the Zeos with the Seagate ST5660A drive. First, I found out why it wouldn't go above 1024/16/63. There's a jumper on the drive that limits it to that. When I removed the jumper, I was able to get 1057/16/63 in the BIOS. (Why Zeos did not remove the jumper, I do not know. When I called their tech support line, the tech was rude and insisted that the drive didn't have any more space on it.) I then installed Caldera Network Desktop, which is built on top of an enhanced version of Red Hat Linux. It *did* work and did not crash. One of the boot messages from the kernel seemed significant. It said something like: ide0: Buggy RZ1000 chip: Disabling read-ahead This could be related to the problem. If this *is* the problem, code to fix it ought to be available in the Red Hat Linux distribution, or so I would imagine. [Note: Caldera decided to treat the drive as 528/32/63. Not sure why it needs to do that under UNIX. But the translation is one of those listed by Seagate in the docs, and it works with only a slight loss of space.] In any event, if my intution is correct here, I can't get FreeBSD running until the read-aheads are disabled. (No, there's no jumper for this on the drive, just as there is no jumper to turn off "green" mode. It's got to be set via IDE.) --Brett P.S. -- I do like FreeBSD's configuration and installation routines much better than the ones that come with Caldera, by the way. That visual configuration editor saves a lot of pain.
