QNX6 on WinME problems (loadqnx.sys) ?

Hi, I have problems when I try to boot QNX6 from windows millenium 4.90.3.
The loadqnx.sys starts but no loads the qnxbase image. No display errors.
I probe making a win98 boot disk and boot from floppy and works fine.
How I can resolve this ?
Thanks,
Alejandro Gonzalez
