<blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">I recently found a need to re-flash the option ROM on an Intel 82574L gigabit<br>
ethernet card. These are a bit more common these days than the 82571 and 82572<br>
and relatively cheap. It turns out this works with flashrom, but it doesn't<br>
detect the PCI ID for the device out of the box. Below is a patch add it to<br>
nicintel_spi.c. Note that there are probably other devices in the PRO/1000<br>
family that would work too.<br>
<br>
Here's an example run with the latest code from svn:<br>
<br>
[...]<br>
flashrom v0.9.7-unknown on FreeBSD 10.0-RELEASE (amd64)<br>
flashrom is free software, get the source code at <a href="http://www.flashrom.org" target="_blank">http://www.flashrom.org</a><br>
<br>
Calibrating delay loop... OK.<br>
Found Winbond flash chip "W25X40" (512 kB, SPI) on nicintel_spi.<br>
Reading old flash chip contents... done.<br>
Erasing and writing flash chip... Erase/write done.<br>
Verifying flash... VERIFIED.<br>
[...]<br>
<br>
FreeBSD detects the device as follows:<br>
<br>
em1@pci0:2:0:0: class=0x020000 card=0xa01f8086 chip=0x10d38086 rev=0x00<br>
hdr=0x00<br>
vendor = 'Intel Corporation'<br>
device = '82574L Gigabit Network Connection'<br>
class = network<br>
subclass = ethernet<br>
<br>
I also added links to the Intel PCIe ethernet controllers programming manual<br>
and the 82574 datasheet.<br>
<br>
Incidentally, thanks to everyone involved for their work in this project. It<br>
helped me out of a bit of a jam.<br>
