Post by a***@gmail.comHave just picked up a PHILIPS Graphics card and need info and or drivers.
It is ISA bus and has(the reason I got it) both 9 and 15 pin output \D
plugs on it.It is I think 256k and has model number badly printed is
D6W6KKVGA?
It has a CHIPS main chip and the BIOS chips have labels with 61672 on them,
it also has a bank of 6 dipswitches by the upper output plug.
Any details, instructions, information or drivers will be gratefully
recieved.
Regards.

That is kinda big for a vanilla frame buffer driver.
The virustotal scan shows it is infected.

I think these are part of offering a Toolbar to the unlucky downloader.
The file has been given a bogus signature in the year 2013.
The file was obviously not originally created in 2013. It
would be from the late 1990s or so. 7ZIP is not doing
a good job of opening it up. So I can't really tell you
what is in there.
In any case, look for more instances of "82C451 driver" on the web.
If that is the only file you can find, the easiest thing to do,
would be to use a Linux virtual machine, open the above file with
WINE program loader, visit the TEMP folder and scoop up the
uninfected contents from there. I use that quite often, to
separate toolbars from the actual files I want. (Then scan
the extracted files again on virustotal.com.)

The chip itself, has a manual.
http://bitsavers.informatik.uni-stuttgart.de/pdf/chipsAndTech/82C451_VGA_Controller_Jul90.pdf
"Maximum resolution 800x600 16 color"
That means each pixel is stored as 4 bits. 800x600
is 480,000 pixels, using 1/2 of a byte each. That is
a total of 240,000 bytes.
It also means, you cannot view a JPG image on the screen,
and expect it to look "normal". Sixteen colors total,
wouldn't even do a good job of displaying a 256 color GIF file.
The frame buffer uses 256KB worth of RAM chips. Which
means, the unit is single buffered, there is only one
frame buffer, barely able to draw a 2D picture. The
design is not double buffered, and there is no room
for an attribute plane.
And this is why I suspect the driver should be a tiny file,
since the card is about as brain-dead as video cards get.
To me, the second connector does not imply dual-head, since
there is so little graphics RAM on the card. The middle
connector is likely to be VGA. The nine pin connector,
I don't know what that would be for. The card uses a
discrete RAMDAC, which maps indexed colors to full
color space (even if limited to 16 colors, they can have
subtle shading - the colors are not fixed).
The chip manual seems to suggest the DIP switches are used
to identify an "instance" of the card. So if multiple video
cards are plugged in, the DIP switch on each card is set
to a unique value. See page 28 of the manual, as the DIP
switch can also control some emulation modes and I/O space
addresses.
Have fun,
Paul
