Due to a change in system requirements at bartal, I decided to remove the 80387 from the unix box, and put it in the dos box where I run most of my CAD applications. Well, The unix machine won't get past "loading the unix system" wit the 387 removed. However, if I also pull the SCSI controller, it will boot just fine from the st-4096. I checked the cmos, and all is correct, as far as I can tell. Is this for real? do you need to have a math coprocessor to run a SCSI disk? This may be the most ridiculous thing I've seen since they announced that you need to have a coprocessor to maintain system security... I'm open for suggestions.

Then I read the release notes. It seems that whether you have a mathco installed or not has nothing to do with whether the machine will boot or not. Per my SCO Unix notes, the kernal must think that a matchco is present. Thus I believe in /etc is a program called emulator or some such which is loaded at boot time (If the mathco isn't present). I suspect that your 4096 has this program and you scsi drive does not. BTW, I have a scsi setup (1542B Adaptec with a Seagate 670Meg drive) and it works great. I also have the mathco installed not because I use it so much, just because I like faster toys!!! Hope that this helps. Rich Douglas doug@ohenry. No sig yet. Lost in the bitbucket.
