The lowest value in BIOS is 4MB but the failure is the same in this case.

Sure it is failing to allocate 0xc0080000 bytes chuck!!!.
Is 8MB the lowest possible value in BIOS? Try to lower
it if possible and see what happens.

There is a virtual alloc error, but i don´t know where it comes from.

Hi,

the amount of memory used as video ram (bios setup) might make a difference.

hope this helps.

Hello,

i´ve a problem with my Geode board ECM3512.

The image for testing the board is based on the Enterprise Web Pad. The
settings are the defaults. The image boots over ethernet connection and
it´s
possible to call ipconfig over CE target Control.

But the display doesn´t show the desktop, its only black screen.
I booted the image over bootdisk with biosloader and over loadcepc.
Are there any settings to activate the display?
Any ideas?

Thanks,
Andy
