Hi guys I am looking to extract the video bios out of the Gigabyte S1081 tablet, I like to learn how to do it so I can do it for myself and others if needed in the future. The bios can be found on Gigabyte website (they won't let me post links) 1) How do I identify which tool for the bios? the flashing tool is called "Win32DiskImager.exe" the bios is called "S1081B.F06" 2) How do I extract the video bios from the bio file? Thanks
Are you still trying to do this? I can give it a shot. Out of curiosity, may I ask what you wish to use this for?
Thanks for replying. Yes I am still trying to do this. The reason is a bit complicated. S1081 has a Cedar Trail processor that have terrible Windows 8 driver support for its GPU. Many Cedar Trail users are stuck because of the poor support from Intel and we are left to fend for ourselves. I want to take a look at S1081 video bios and compare to a Clover Trail processor GPU which supposed has exactly the same core and has excellent Windows 8 graphic driver. It is a long shot but I like to see what I can do with it.
that's the link. You can extract the boot.img using 7zip. Then extract the F06 file from boot.img with 7zip. Thanks for posting Tito
i am looking for one as well. Those devices just came out. The Samsung ATIV Smart PC 500T is one such device and has a firmware update program on its support page. The problem is, it is just a software and it downloads over the internet. and it checks bios before doing so. If there is only a way to fool it.
I can dump the contents BIOS using the Phoenix Tool, and one of the files has a string that mentions "VGA BIOS" in it, but that's all I can find. I have no idea what I'm looking for here. I don't know the size, or any strings or HEX code that may be used to signal the start of the VBIOS. I'll look into getting a copy of the Samsung ATIV Smart PC 500T BIOS.
that's awesome, which file has the video bios string? This is the first time I am using Phoenix Tool.
While I don't know the version of vbios for this rom, i have a similar one that is at 1059, and I know someone with a version 1050. So search on 105. Thanks
The name of the file is A062CF1F-8473-4AA3-8793-600BC4FFE9A8_1_157.ROM. Somewhere near the middle of that file is the following string: Code: Intel(R)XX Graphics Chipset Accelerated VGA BIOS I have no idea if this means that this is the VBIOS, but it may be a starting point. ~Drew
wow, thanks drew, let me look at that file. Could VGA bios be packed with other parts of the bios or is it always has its own file?
Honestly, I have no idea. It would be helpful to have a different BIOS with a VBIOS in a known location to compare with.
Thanks for all your help. Let me take what you have shown and go back to the lab to mess around a bit more . I will ask you again if I make any progress. You have been a great help
