In the latest issue of PC Week I see a blurb saying that SCO is now
shipping a new version of its Unix, SCO SV/386 3.2 version 2.0, which
"runs faster, supports extended memory and" easier security mgmt.
^^^^^^^^^^^^^^^^^^^^^^^^
My question: what does this mean? Extended memory for UNIX? Isn't
extended memory a DOS concept?chip@chinacat.Unicom.COM (Chip Rosenthal) (07/25/90)

I think what they are trying to say is that their memory support has been extended, and now up to 256Meg of main memory can be handled. The old version, according to the Jan 90 Configuration Guide was: The SCO UNIX System V operating system can use up to 16 Mbytes of real memory with a "standard" ISA, EISA or MCA computer. Some system manufacturers are supporting up to 64 Mbytes of physical memory. On some of those computers, SCO UNIX System V can make use of the entire 64 Mbytes. (All along, the main memory beyond 1 Meg used by all unices has been the so-called extended memory.) I bet the folks who like to run emacs under X will be glad to have this new feature (gratuitous flame bait). -- Chip Rosenthal | You aren't some icon carved out chip@chinacat.Unicom.COM | of soap, sent down here to clean Unicom Systems Development, 512-482-8260 | up my reputation. -John Hiatt

Extended memory for UNIX? Isn't >extended memory a DOS concept? It means the new version will support 256MB of RAM, instead of the current 16MB. Remember the article was written by PC (<-) Week, and not UNIX World, Review, etc. The drivers are more refined (EISA support), as is the kernal I believe, and C2 sercurity management is supposed be easier. Its a pain right now. I have no affiliation with SCO other than being a satisfied OpenDesktop developer who can't wait to get the next version. I've got a SystemPro here that can't wait to get loaded up.

ISA DMA design can only reach the low 16Mb of physical memory. "Extended memory" support means that we have worked around this limitation. -- Chapman -- Brian Chapman uunet!sco!chapman Pay no attention to the man behind the curtain!

What this means is that, for machines that will handle it, SCO Unix 3.2 v2 will see and use memory in excess of 16MB. -- Roger Knopf <standard disclaimer applies> SCO Consulting Services "The True Believers will...formulate uunet!sco!rogerk or rogerk@sco.com a message that even a monkey could 408-425-7222 (voice) 408-458-4227 (fax) understand." --Jeff Tye

Do you, by the above statement, mean to say that the first cut of SCO UNIX 3.2 would not utilize memory above 16 MB? What would happen in such a configuration -- would it be ignored? would it cause problems? In the new 2.0 release, how do you handle DMA between addresses above 16MB on an ISA bus machine?
