- help
- 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 initialization.
- 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'.
