booting on CD

Hi: I made an bootable cd which runs the software on qnx4.25, photon 1.14.
the software on the Cd runs fine under english and european languages.
But under japanese and chinese, it takes a while for the screen to display
all the characters. I copy all the font files to a ram disk, and restart
the font manager “phfont -X -d /ram/qnx4/photon/font/ &”. Thought this
willl speed things up, but didn’t help…
