Hi, I have a AST Rampage 286 that I have had for some time. At the time I bought it LIM 3.2 was the latest which is what I have used the board for. I keep hearing about LIM 4.0 and was wonder if that is a software upgrade or a hardware update. It there is a limitation in the board itself that prevents it from supporting LIM 4.0, can anyone explain what it doesn't do that a 4.0 board would? It maps a block of memory into the first meg, what else would it have to do? Frank P.S. If it is a software upgrade does anyone know how much AST wants for it?

The AST Rampage boards were designed to support EEMS, supported by AST, Quadram, and I think Ashton-Tate. The new LIM 4.0 is not much more than the old EMS 3.2 + EEMS, but with different function numbers. So the Rampage boards have no trouble running LIM 4.0 (they have the extra hardware registers needed to make a full implementation practical). All AST wants is for you to call their BBS at 714-852-1872 and download the new driver. I believe it is called REMM42.SYS or something like that. Make sure its for the RAMPAGE boards (read the file descriptions). Last time I knew, Quarterdesk (authors of Desqview) did not feel that the AST LIM 4.0 EMS driver was very good. At that time, they recommended staying with the EEMS driver when using their software. So be warned.

LIM 4.0 isn't enough... -- Jason Merrill jmerrill@jarthur.claremont.edu

Desqview requires LARGE FRAME LIM 4.0 for efficient multitasking. Like windows3 (real mode) it can also multitask in small frame EMS (64K, no backfill), but it does so by doing lots of massive memory moves. -- ___Mark S.

I keep hearing about LIM 4.0 and was wonder if that is a software >upgrade or a hardware update.... The Rampage was actually AQA EEMS which was a superset of the LIM 3.2 EMS standard. The EEMS enhancements where incorporated into the later LIM 4.0 EMS standard. Hence, the Rampage boards can be LIM 4.0 compatible at the HARDWARE LEVEL with just the addition of a new remm.sys driver. >P.S.
