checking the BIOS video mode paramter table. Now syscons uses the
parameter table even if some bits in the table are different from the
current VGA register settings.
Even if comp_vgaregs() finds that the BIOS video parameter table looks
totally unfamiliar to it, syscons allows the user to change the
current video mode to some modes which are based on the VGA 80x25
mode. They are VGA 80x30, VGA 80x50, VGA 80x60. In this case the user
will be warned, during boot, that video mode switching is only
paritally supported on his machine.

Fixed nonblocking mode. It was per-device instead of per-file.
Don't depend on gcc's misfeature of rewriting char args in old-style
function definitions to match wrong prototypes. Break K&R1 support
to fix this quickly.
actually offsets, they are offsets scaled by dividing by 2^cy_align.
I use different values for cy_align since the -current values are
unnaturally scaled, so I need different offsets, and the wrong
offsets got committed.

changes:
o rip the old select from his distribution to prevent extra pollution
o the code now uses audio dma, helps reduce clicks
o improved card support, should work in full duplex on sb16 cards
o add better voxware ioctl support pointed out by Joao Carlos Mendes
Luis <jonny@coppe.ufrj.br>
o remove an unused file that I included for more complete history
o and MANY other changes
I have personally tested this code with a CS4237 based card and an AWE32
(non-PnP). Both cards worked fine in 8bit and 16bit mode.
This make the Miro PCTV work for me, including audio, and should
hopefully fix the other audio problems some people have been having.

to use the function call, but since none of the existing drivers
are loadable, this made things cleaner and boot messages nicer.

need the driver-specific suspend routines.)

- Move the configuration option SC_HISTORY_SIZE from syscons.h to
syscons.c.
- Define the maximum total number of history lines of all consoles.
It is SC_HISTORY_SIZE*MAXCONS or 1000*MAXCONS; whichever is larger.
CONS_HISTORY will allow the user to set the history size up to
SC_HISTORY_SIZE unconditionally (or the current height of the console
if it is larger than SC_HISTORY_SIZE). If the user requests a larger
buffer, it will be granted only if the total number of all allocated
history lines and the requested number of lines won't exceed the maximum.
- Don't free the previous history buffer and leave the history buffer
pointer holding a invalid pointer. Set the pointer to NULL first, then
free the buffer.

floppy drive #0, regardless of what the CMOS says. This is intended
as a bandaid for those plagued with Compaq's idea to not announce the
floppy drive on their `Aero' notebook.
Using the device flags is not very nice (in particular since they
aren't per-drive but per-controller), but still looks a lot better to
me than the disgusting guesswork hack that was recently posted to
-hackers.
Doc update will follow shortly.

savers are also modified so that they behave in the same way as the
blank saver on MDA and CGA, although it's not the way these screen
savers are supposed to work, but fading monitor and tickling green
monitor cannot be done on MDA and CGA, AFAIK. So, this is the second
best solution.
As of this change, the current state of support of screen savers is
summarized in the following table.
MDA CGA EGA VGA
blank OK OK NA OK
daemon OK OK OK OK
fade * * NA OK
green * * NA OK
snake OK OK OK OK
star OK OK OK OK
OK: works
NA: doesn't work, the module cannot be loaded for this adapter.
*: behave the same way as the blank saver.
As you can see, EGA is left out for now. But, we can do no better, as
EGA registers cannot be read...
