Using Flat Drivers

My video adapter is an Cirrus Logic CL-GD5436 (On-Board). Photon does not
detect my video adapter and loads the unaccelerated VESA Driver.

When I booted my same system with the QNX RTP Demo disk, it loaded some Flat
Drivers (Hydra??) that had acceptable resolutions & colour depth.

So my question is how could I use those flat drivers that came on the demo
disk with my installation.

Is it using the VESA driver (devg-vesabios.so) or the VGA driver
(devg-vga.so)? The VESA driver is the “flat driver” and provides
resolutions and color depths that are taken from the video BIOS on cards
that are VESA 2.0 and greater. The VGA driver is “safe mode” - 640x480x4.

If Photon used any driver whatsoever, then it did `detect’ your video
adapter.

That is not a `QNX RTP Demo Disk’. It is a QNX4 demo disk. QNX4 and RTP are
completely different products.

The unaccellerated VESA driver is the same thing as the Flat driver was
under QNX4.

You can’t. They won’t work at all.

You’re much better off helping us figure out why the RTP VESA driver does
not offer the same modes that the QNX4 demo disk offered you.

Check the list of supported video cards:

I don’t belive that your chipset it currently supported so the driver you will
have to use is the VESA driver.

Does the RTP offer any different resolutions? The flat driver and the vesa
drivers are the same. Use the VESA driver to startup Photon, then once
in Photon, use your mouse and right click on the desktop. Select
“Graphics Config”.

From there you SHOULD have several resolutions avail to you.
