- There is a lot of cunfusion over the "286 based" products that you have
- referred to above. They do not require a 286, they DO require that EITHER
- a LIM 4.0 hardware compatible EMS board or a shadow RAM chipset. They use
- the capabilities of these two types of hardware (that are capable of making
- unused areas between 640 and 1024 mappable to RAM) to load programs high.
- They DO NOTR enable EMS support in these systems. Some shadow RAM chipsets,
- like the one in ALR 286's, also support making EMS via the chipset. This
- requires a driver provided from ALR. You friend should contact VLSI. If
- the chipset (I can't see VLSI using someone else's chipset for their MB's
- when they make their own) is capable they could provide a driver.
-
- There are some EMS emulators, like Turbo EMS, but I think he would find
- them woefully inadiquate.
