QNX 4.25Patch Q Upgrade

HI All,
If any one did Fsys Atapi driver upgrade from 4.25 patch G to Patch Q. Please let me know the procedure.
I am following below procedure.
Copy below files to respective folders.
Above files are PatchQ files.
And build boot Image and copy os Image to /bootable/.boot
Two issues I am facing if I use this Procedure

  1. Network is not coming up. manually I have to make N/W up using ifconfig
  2. booting hangs with message “Press ESC for alternate OS”, and it boot if I press ENTER.

Please let me know hoe resolve these isses or proper upgrade
