Problems with Embedded Photon... black screen !

Hello,

I’m working with a x86 embedded system (PC104 x84 svga/vga card).
Little problem : the io-graphics driver seems to start, but the screen become completely black… and stay black :frowning:

Here is the script I use (I’m working with IDE) :

pci-bios &
waitfor /dev/pci

Anyone can help me ? Thanx !!!

Hi mate,

post the output of the ‘pci’ command. You probably load the wrong driver.

Try the VESA driver and try it without the -P option

I don’t have my script at hand. I’ll post it later.

Good luck

Always the same problem…
My card is compatible IBM vga and svga.
