+         The scrollback buffer of the standard VGA console is located in
+         the VGA RAM.  The size of this RAM is fixed and is quite small.
+         If you require a larger scrollback buffer, this can be placed in
+         System RAM which is dynamically allocated during intialization.
+         Placing the scrollback buffer in System RAM will slightly slow
+         down the console.
+
+         If you want this feature, say 'Y' here and enter the amount of
+         RAM to allocate for this buffer.  If unsure, say 'N'.

+         buffer.  Each 64KB will give you approximately 16 80x25
