Web site update? Should I update the site?

The code should probably be committed to the tree first, don't you think?

Thanks,

and

tyan s4985
( http://www.tyan.com/product_board_detail.aspx?pid=271 )

are only quad socket 1207/ f boards on market discounting sunfire x4600-m2

query is two fold

  1 what is future of quad core barcelona support on 1207 / f
  2 what are odds of these boards supported

i do not yet own either board but linuxbios support would sway me

Besides does anybody know if the second free place on the PCB is still connected in a proper way to enable diy dual boot bios. Does anybody know which spi flash type is placed on the m57sli-s4.
Uhm - none I think. If you look closely at the second (free) place, you'll see paths for a plcc socket, and within that, paths for an spi flash part

You only need the outer ring for the plcc. That's what the first chip is - when ours came off, there was nothing underneath.
I would prefer not to remove the first part but solder something on the free space. I think i have to search my multimeter.
I don't know how that second chip is wired up, or how the fallback mechanism works...
I wonder whether the inner spi flash part is indeed a fallback for the outer plcc flash memory. This is not necessarily so. Like on NICs, spi is for config data (MAC <at> ,  PHY speed and such) while plcc is for BOOT ROM.   -- Q

Programming i2c video-out

hey Joe,

I'd guess, during testing, the sequence would make not much difference.
Once the code is working, the earlier it gets called, the more you could
output onto TV which would be desirable. maybe use it as debug output
device.   greetinx: --Q

what is the content of those SPI chips ? is that known ? (maybe dumb

TV encoders are not standalone devices. They get pixel data from your 
graphics device, and they either provide or receive sync signals, 
blanking and clocking either to or from the graphics device. It doesn't 
matter if these devices are programmed over smbus or over graphics 
device local I2C/GPIO lines.

So this is an integral part part of graphics device initialisation. 
As such, it is all up to the VGA BIOS, or, if available, up to the 
direct support of certain graphics devices.

Re: Programming i2c video-out

Yeh, As soon as I get my setup working, I think I am going to call the  
tv-out driver just after the superIO initializes this way when ever  
the vga bios starts it's output to DVOA the tv-out chip will be ready  
to encode.

I understand video encoders are not standalone. They receive input  
from your GPU, in my case it is embedded so the northbridge, encode  
it, and send it out the output. I have a vga bios that outputs to  
DVOA. This is the the port that is connected to the input of the video  
encoder. Unfortunatly (intel) never released a module for this video  
encoder. So, this is what I want to do. Write a driver to initialize  
the video encoder and then when the vga bios starts outputting to DVOA  
we should have signal correct?

Thanks - Joe
