toshiba satellite video configuration problem

I have posted this message before, but I have lost the answer… sorry,
beginer’s foolishness. Could you help me again?

Could anyone help me?
I installed QNXRTP 6.1 in my notebook and the video configuration doesn’t
work. I can only use the vga640x480x8 configuration. But I have already
installed the version 4 of QNXRTP and the 800x600x16 configuration worked
just fine. The driver that worked before was the
“io-graphics -g800x600x16 -IO -d0x5333,0x8c01”, but it doesn’t
work with the version 6.

Thanks a lot!
