the PIII has onboard video

not as far as i can see. (i use fresh copies)
i suspect [1] has something to do with using the pd open or close 'message'
with a non-existing file.

or what does "every time at a change in the rendering" mean exactly?
every time the content of the GEM-window should change

it's not clear to me how to use this object, there's no help.
connecting the inlet with a loadbang causes Pd/GEM to quit immediately.
leaving the object by itself, with a print on the first outlet, gives

i tried to use more then 16 k for the VideoRam: this also causes Pd/GEM to
quit at rendering the first picture.

just now i found in the system message.log after the crash:
 pdextended[1702]: segfault at 0 ip (null) sp bfcc1acc error 4 in

doing it again:

pdextended[2045]: segfault at 0 ip (null) sp bfb87f3c error 4 in

going back to the default VideoRam (= no changes made by me)

pdextended[1431]: segfault at 0 ip (null) sp bfe1aecc error 4 in

should i make a bug report on this? (i'm on Pd-ext 42.5 with GEM 92.3)
