I was referring to all memory 0 through 1M+64K-16

"High memory" is usually the memory above 1M; 640K-1M is usually
called "upper memory".  This is based on "dos=high" and "upper memory
blocks".

Maybe we should stick to numbers...

In any event, the limit of _dos_ds should be 1M+64K-16 (1M+64K since
we're 4K granular).
