Lousy Video On QNX 6.2.0

I have a Dell machine that is dual-booted between Windows XP and QNX
6.2.0. Under Windows, I can set the video to 1600x1200 true colour.
However, under QNX, the best I am getting is 1024x768 with 8-bit colour
using the vesa driver.

Windows XP reports that I am using an on-board Intel 82865G video controller
which is on board.

How can I increase the resoloution and colour depth?

Thanks in advance,
