Hi all,

         I have made the codes run into the vsmbios. And it hangs on
pci_sanity_check(). Anyone has the same problems?

I have 2 questions:

1)      I have downloaded VSA code, and VSA implements a softVG, do I need
to make a VGABIOS myself from linux?

2)      If I need a VGABIOS, where should I put it in the image??


         Thanks, any advice would be well appreciated.

Hi all,

         I am running LinuxBIOS on gx2 and cs5535 platform. Now the code
begins to enumerate devices in northbridge. 

And the code hangs just after prints out _do_vsmbios_. 

         I find the next function called close to that print is
_unrv2b((uint8 *)rom, buffer, &ileg)_, and it seems that cpu is in dead

I am thinking that maybe my linuxbios image is not correctly built. The step
I build image is divided into 2:

         Firstly, I build out a _linuxbios.rom_ image;

         Secondly, I use _buildrom_ tool from util directory to build
vsa2.bin and linuxbios.rom together out as the final image.

         My flash is 512KB, so I put vsa2.bin at 0xfff80000, and
linuxbios.rom at another side of flash.

         Is my step correct??


         By the way, after I built out vsa image, it generates some other
images, which one should I choose? Including: vsa2.bin, olpcXXX.bin, some
vsms and so on….


         Any advice would be well appreciated.
