-       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'.

-         Enter the amount of System RAM to allocate for scrollback
-         buffers of VGA consoles. Each 64KB will give you approximately
-         16 80x25 screenfuls of scrollback buffer.

-       default n
-       help
-         Say Y here if the scrollback history should persist by default when
-         switching between consoles. Otherwise, the scrollback history will be
-         flushed each time the console is switched. This feature can also be
-         enabled using the boot command line parameter
-         'vgacon.scrollback_persistent=1'.
-
-         This feature might break your tool of choice to flush the scrollback
-         buffer, e.g. clear(1) will work fine but Debian's clear_console(1)
-         will be broken, which might cause security issues.
-         You can use the escape sequence \e[3J instead if this feature is
-         activated.
-
-         Note that a buffer of VGACON_SOFT_SCROLLBACK_SIZE is taken for each
-         created tty device.
-         So if you use a RAM-constrained system, say N here.
