Use set_con2fb_map() to select the primary display driver instead of using unbind_con_driver() and bind_con_driver(). Using the former is much simpler and safer than the current one.

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/>.

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 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'.

This enables support for text mode selection on kernel startup. If

you want to take advantage of some high-resolution text mode your

|
card's BIOS offers, but the traditional Linux utilities like
|
|
SVGATextMode don't, you can say Y here and set the mode using the
|
|
"vga=" option from your boot loader (lilo or loadlin) or set
|
|
"vga=ask" which brings up a video mode menu on kernel startup. (Try
|
|
"man bootparam" or see the documentation of your boot loader about
|
|
how to pass options to the kernel.)
