IMPORTANT NOTICE FOR ALL users of CT65554 or Toshiba laptops

Hello,

After reading carfully comp.os.qnx I tried:

  1. Change in BIOS the VGA segment: C000h
  2. Reinstall RTP in Toshiba Satellite CDT400
  3. Now photon is working on in 800x60x16 :slight_smile:

What the heck is this ? Were problems reported before with this model of
Laptop but now is ok ?
Why changing the VGa segment mem let Photon to show up correct?

Good question. I’m trying to figure this out right now. I’ll see
if there’s a way to make it work when the BIOS is not at c0000, like
it is on almost every other PC ever built.

I think you were lucky though, we have a Toshiba laptop here, which,
even though the BIOS is set for C000, still had other problems, some
of which we have been able to fix.

There was one problem, in particular, which only showed up if
you booted off a windows parition.

Did you install in a Windows, or in a standalone partition?

Hi,

The installation was a standalone partition … Anyway Photon is a bit
slow using C000h or maybe it’s because of my chipset.
