Hello,<div>1- The chip was not erased, it contained the motherboard BIOS. Before starting the tests, I programmed all the chips using the motherboard vendor update disk.</div><div>2- The erase.bin only contained 0xFF, so the chip was erased correctly.</div><div>3- The bios.bin file contained the original bios.</div><div><br></div><div>Greetings.</div><div><br><br>> Date: Sun, 30 May 2010 16:14:51 +0200<br>> From: uwe@hermann-uwe.de<br>> To: master_darkman@hotmail.com<br>> CC: flashrom@flashrom.org<br>> Subject: Re: [flashrom] Report for SST29EE020 part<br>> <br>> Hi,<br>> <br>> thanks for your reports.<br>> <br>> On Fri, May 28, 2010 at 07:55:20PM +0200, Néstor a.k.a.
