My graphic card is Poulsbo. While booting up, the system just dies.The screen turns not only white or black but with 
many colors.I've looked into te file
 
1. /etc/system/enum/devices/graphics
This file includes the following lines. I don't see any problems.device(pci, ven=
8086, dev=8108)start/wait( dispconf -i "0x$(ven),0x$(dev),$(index)" -d poulsbo )requires/wait( $(
IODISPLAY_CMD), )mount(-Tio-display "vid=0x$(ven),did=0x$(dev),deviceindex=$(index)" )

The plateform I'm using is menlow, Poulsbo SCH.
I am trying to boot QNX v6.4.1 (released version).

My display.conf is showed as below.
device {
    drivername=poulsbo
    vid=0x8086
    did=0x8108
    deviceindex=0
    modeopts=/etc/system/config/poulsbo.conf
    display {
        xres=1024
        yres=768
        refresh=60
        pixel_format=argb8888
    }
}

The original poulsbo file is:
general:uselvds=0,usesdvo=1,overlaypipe=0,planecpipe=0,dualview=0
pipea:pllref=96000,dpll=0x44000c00
pipeb:pllref=96000,dpll=0x48000c00

Because this machine - display is connect through SDVO,
I changed the original poulsbo.conf to this
general:uselvds=0,usesdvo=1,overlaypipe=0,planecpipe=0,dualview=0
pipea:pllref=96000,dpll=0x44000c00
pipeb:pllref=96000,dpll=0x44000c00


I tried booting into text mode and then starting photon but the result is same.
I am not able to capture sloginfo since the system crashes. I tried telnet from other machine but in vain.
Please help me.
