Waiting for chips, sockets and a replacement mothercard (just in case), I try to find the EC code both from a dump of th flash rom and from the Dell bios file. But from the LPC47N252 datasheet I understand that it is supposed to execute its firmware directly from its own flash (which doesn't exist on FDC37N958FR). If I'm right, the bad point would be that I have no chance to get a blob from FWH but the good point could be that we can forget about EC code (unless we want to update it). Am I right ???
