This article is from a FAQ concerning SCO operating systems.

This depends on your OS version:
5.0.4's support for more than half a gig of memory is more stable than 5.0.2 or 5.0.0 with the LSS; if you require this much memory, you should seriously consider upgrading to 5.0.4.
You can find details on the mem= bootstring in your man page for boot(HW); the quick summary is that
Boot : defbootstr mem=1m-768m
will instruct the system to scan for 768 MB of RAM. Do not specify more memory than the maximum for your release.
