Could not use image

[xhark]

Hi,

I need help to activate a[/code] background picture.

I use undionly.kpxe, generated on rom-o-matic with :
Advanced > PXE bootstrap loader keep [Keep PXE stack method 1 (.kxpe)
Choose a NIC type > undioonly
Download protocols > TFTP, HTTP, HTTPS, FTP, NFS- IMAGE_PNG, PNG image support
- CONSOLE_CMD, Console command
- CONSOLE_VESAFB, VESA framebuffer console

My menu.ipxe :

Code:

#!ipxe
console --x 1024 --y 768
console --picture http://192.168.0.17/images/splash.png --left 32 --right 32 --top 32 --bottom 48

menu
...

When I boot on nic with a laptop this error appears :

Code:

http://192.168.0.17/images/splash.png... ok
Could not use picture: Operation not supported (http://ipxe.org/3c008003)
Could not boot image: Operation not supported (http://ipxe.org/3c008003)
No more network devices

I don't understand why
Is PNG must be 24 or 8 bits?
(The resolution of my image is 1024 x 768)

Any idea ?
Thank you
