And anyway whats the VGA for?
If it is the a PC system's only video board, it must do VGA.
I do not know anybody who would like to configure his BIOS settings
or install operating system on an Ethernet attached display. It is
very inefficient to focus on that, as everybody has a display today
The most popular brand of PC remains "White Box". This brand is even
more popular with users of BSD & Linux because it is the only way to
escape the M$ tax. These systems do not come with a display, you
purchase what you want.
That is out purpose here, to make a video card for users of open software.
There is also the upgrade market for people that have a system that has
an integrated motherboard video chip but will not display H.264.
- so near nobody will use this feature (it requires only BIOS coding
for a dedicated ethernet card and a compatible display card -
existing one, we do not want to make it.. well we can if you want to
raise the cost of the solution).
Actually, if this will work with only the BIOS VGA functions, all that
is needed is a BIOS PROM that can be plugged into the Ethernet card if
it has one or a BIOS card. As I presume you know, the BIOS on PCI card
is automatically installed.
What about to make it just an Ethernet attached second video card -
you load a kernel module and there you go - raise your X display by
another desktop. Or run a separate X for it - using some VNC like
protocol for 2D or directly run X on the device for these 2D things
(informative display). For video it should just listen on a TCP port
an expect an video stream thrown there.. the device should be quite
autonomous.
Wouldn't be an external video card then, would it. I fail to see your
point. You saying that the solution is to have two displays. This also
might be nice, but I note that then it doesn't matter if people already
have one display, does it?
Maybe it would be better to re-clarify the requirements here again,
if it should lead to some product..
It remembered me a joke about operating systems and airplanes:
"UNIX: Everyone brings one piece of the plane along when they come to
the airport. They all go out on the runway and put the plane
together piece by piece, arguing non-stop about what kind of plane
they are supposed to be building."
The way I heard it was that the plane was too heavy to take off.
The requirements were fairly clear: a video card that is external to the
system connected by a serial connection (Ethernet, USB-2, or IEEE-1394).
The discussion has drifted towards using a video DSP chip, but other
methods are also OK.
What needs to be clarified is what to do about VGA hardware
compatibility. I don't think this is needed -- that VGA BIOS
compatibility is sufficient.
