The PC Chips M-209 is a 286 motherboard capable of up to 20MHz operation, with hardware EMS support.


Memory

Hardware EMS

This motherboard works with the Hedaka D60 chipset drivers, which provide an EMS interface allowing a chosen amount of memory above 1MB to be accessed as EMS. Thus it is possible for this board to be configured to have conventional, EMS, XMS and Int15 extended memory available, all at the same time.

UMBs

The chipset does not natively support backfilling unused parts of upper memory with UMBs. However if EMS support is not required, third party drivers can use the hardware EMS facility to make a small amount of memory available in as UMBs.
