Hi,
I am trying to use a Toshiba 4090XDVD laptop with either Photon or QNX
Windows and so far I have been unable
to make the graphics adapter work.
The laptop has a Trident 9525 chip, is there any ‘special’ driver I need or
this is just not supported?
Thanks in advance for your help.

I have the same chip in my Toshiba 4100XDVD. It’ll work in VGA, of course, but
that’s just cruel 
I’ve tried to get it going in 800x600 using the VESA driver without success.
The Trident website certainly implies that the chip is VESA 2.0 compliant, but
without ever actually saying so.
Maybe someone from QSSL can tell us whether or not it should work in VESA
mode…?

Well our opinion is that all graphics chips/cards should work in VESA 2.0
mode, but that doesn’t mean they do.
Noone mentioned any symptoms, so it’s difficult to come up with any
suggestions. With laptops though you can always try pluggin in a monitor to
see if the BIOS is just stupid and assumes you want to send to a monitor
instead of a flat panel.
You could also try whatever key sequence the laptop vendor provided to
switch between the monitor and the panel.
You could also try to use a video mode that is exactly the same size as the
flat panel.
