NOTE: The use of the 16-bit

EMS

transfer

mode may not work

on AT's with clock speeds of 8 MHz

and

higher; we suggest ex-

perimenting with the RAM

3000 Deluxe to see

if

it will work.

For

AT compatibles with very high clock speeds

(10

MHz

and

higher), set the RAM 3000 Deluxe to the 8-bit EMS

data

trans-

fer

mode so EMS memory will work

at

the higher clock speeds.
