Unix, Xenix and ODT General FAQ

This article is from a FAQ concerning SCO operating systems. While some of the information may be applicable to any OS, or any Unix or Linux OS, it may be specific to SCO Xenix, Open Desktop or Openserver.

There is lots of Linux, Mac OS X and general Unix info elsewhere on this site: Search this site is the best way to find anything.

I licensed an additional CPU but the system doesn't see it or use it.

You need to actually install the SMP software. It's on your original installation CD, the same one you installed the OS from. Stick that back in, run "custom" and find it on there.

It's easy to make the mistake of LICENSING that software without installing. You need to install it!

By the way, are you sure you really need this? If "sar -q" doesn't consistently show a runq of more than 1, smp is going to do nothing but slow you down- spending the extra money on hardware and another $1,000.00 for the license doesn't make sense if you don't need it.

The SCO SMP will take advantage of hyperthreading as of 5.0.7 (but see "p4 pentium iv hyperthreading osr5 acpi mps cpu tables"). You have to have the Maintenance Pack patches installed.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
