I have this nasty suspicion that it had hardware for 3.2, as that was what the manual indicated. ELIM 4.0 was only in the Addendum that was tacked on. I don't have any applications that make use of the 4.0 functions, but it run LIM 3.2 stuff fine.

Well, The previous posters are all correct. The EV-3000At is an extended memory card. It is an expanded memory card. It is a 640k backfill card. It is all of these. The card supports EMS 3.2 in hardware, and Everex now supplies an EMS 4.0 software driver. Hence, with EMS 4.0, the registers necessary to make EMS applications run fast are missing. The card can be configured to be extended and expanded concurrently, and backfill RAM on machines with less than 640k. The same is true (except backfill) for the EV10000AT card. Using 1mbit chip makes for a 10 Meg expansion card. I use the EV-3000AT in extended mode on an old 16MHz modified to 20MHz pre-step Everex cached machine (6250 dhrystones). Sure the EV card is only 16 bits, but who cares if all the bench marks say extended memory access is 20% faster than a 20MHz IBM PS/2? So, now you all know 'just the facts jack'! -- Tim Margeson (206)253-5240 PO Box 3500 d/s C1-022 @@ 'Who said that?' Vancouver, WA. 98668 e-mail replies to: timothym@tekigm2.MEN.TEK.COM

If you are having trouble with programs that use expanded memory check the board and the software for LIM X.X compatibility.

They wrote a driver to emulate LIM 4.0 in software, no more. You can probably get the driver by contacting Everex. Note that this is S/W emulation only, it does NOT support H/W specific things such as DMA and multitasking in expanded memory.
