x86 BSP generic

Hi there,
I downloaded the x86 BSP for QNX6.6 which needs patch-660-3885-diskimage.tar before It would be used. patch-660-3885-diskimage.tar is not a source but a file, diskimage. However, there isn’t any instructions for patching the patch to QNX6.6. With find command, I managed to see a copy of diskimage file in $QNX_HOST/linux/x86/usr/bin/diskimage. I presume this file, diskimage would need to be replaced with the one of patch-660-3885-diskimage.tar. Any comments?

Thank you.
