Some PCI devices can change their device ID based on a configuration register or two (I know the XGI Volari can do this for instance). It is possible that the proprietary BIOS changes the ID for some reason.On 03/30/2015 11:24 AM, Iru Cai wrote:
Hi,
I'm trying to build Coreboot for ThinkPad X220. I first backup the
vendor BIOS, then use UEFITool to extract a VBIOS. The romheader program
detects the ROM's PCI data structure and reports the device id is
8086:0106, but the VGA controller's device id is 8086:0126. I extracted
the video ROM from a running X220 memory and use romheader to test it,
the result is still 8086:0106. How could this happen?
