Saying Y here will allow you to use Linux in text mode through a
|
|
display that complies with the generic VGA standard. Virtually
|
|
everyone wants that.
|
|
|
|
The program SVGATextMode can be used to utilize SVGA video cards to
|
|
their full potential in text mode. Download it from
|
|
<ftp://ibiblio.org/pub/Linux/utils/console/>.
|

Say Y.

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'.

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.

---help---

Say Y here if you have an old MDA or monochrome Hercules graphics
|
|
adapter in your system acting as a second head ( = video card). You
|
|
will then be able to use two monitors with your Linux system. Do not
|
|
say Y here if your MDA card is the primary card in your system; the
|
|
normal VGA driver will handle it.

To compile this driver as a module, choose M here: the

module will be called mdacon.

If unsure, say N.

If this option is selected, the framebuffer console will
