Oops, forgot all about the memory configuration being fixed, and I haven't had a chance to play with the VIDEO_CONSOLE=1 option yet (old story about not being enough hours in the day... :-) > > - Line 364-367: > 0 - Disable Framebuffer > 1 - 1 Mbyte > 2 - 2 Mbytes > 8 - 8 Mbytes > > This is incorrect.

Will correct that, although what I can remember from the northbridge docs is that a setting of 0 also disables the framebuffer - perhaps this option is really a 'have framebuffer, but don't share with it memory option' > > Also, now I use folowing lines in the config for the VGA BIOS image to be > patched in the romimage: > option ZKERNEL_START=0xfffc0000 > option VGABIOS_START=0xfffe0000 > addaction romimage dd if=/path/to/vgabios.bin of=romimage bs=65536 \ > seek=2 conv=sync conv=notrunc > This way you don't have to handcraft the vga+eb payload. so this copies the vgabios into the rom image after the payload (not the otherway around) doesn't copying 65536 bytes to 0xfffe000 overwrite the Linuxbios part of the rom image ? or is that done afterwards, in which case the LinuxBIOS would overwrite part of the vgabios image... althought, I think the VGA bios is only 48K in size isn't it ! I'll have to try this, just to get my head around what's happening !
