QNX 6.3 - boot option ??


I installed QNX 6.3 on laptop with graphic card sis630.
While booting - system enables (perhaps) framebuffer and
screen on my LCD is smudged. And then appears big white
smudge and I can see nothing… (I can’t eaven change settings)

After installation of Linux - it was enough to write “vga=normal”
or “linux nofb” as boot parametr in lilo.
How can I in QNX give such parametr on the start CD?

Thanks for help,

so i know you can do it only (?!) when you build a new os image - so there you can configure anything
