Little misunderstanding here.
I beleive the correct description would be:
KS 3.1 can take 512k of your memory if you relocate it to fastram.
Then it would take 512k of fastram since the ROM is 512k large. Since the machine in question has only got chipram it remains in rom and is not debet to the free memory pool.
It used to be a mayor advantage having an OS in ROM that takes no RAM ;-)
