In which case you use a hacked up ramdisk driver that includes the EMS page
selection code (whatever that may entail) and then use the resulting block
device as a swap device with a higher priority than your disk swap. (You
probably want to do the ramdisk-swap thing regardless of whether it is EMS
or XMS, since the RAM on the ISA bus will be considerably slower than RAM
on the motherboard.)
