-			At this point, you should wire up your programmer according to it's documentation. For me, this was (see: "SparkFun cable pin reference"):<br/>
-			<a href="http://dangerousprototypes.com/docs/Common_Bus_Pirate_cable_pinouts">http://dangerousprototypes.com/docs/Common_Bus_Pirate_cable_pinouts</a>.<br/>
-			Correlating with the following information, I was able to wire up my pirate correctly:<br/>
-			<a href="http://flashrom.org/Bus_Pirate#Connections">http://flashrom.org/Bus_Pirate#Connections</a><br/>
-			And by following that advice:<br/>
-			<a href="http://www.coreboot.org/Board:lenovo/x60/Installation#Howto">http://www.coreboot.org/Board:lenovo/x60/Installation#Howto</a>.<br/>
-			(it says X60 but instructions are virtually the same for the T60, with except to physical differences in how to disassemble the machine)<br/>
-			Note: that last page says to wire up only those 5 pins (see below) like that: 1, 2, 4, 5, 6.<br/>
-			Note: and then, for power it says (on that coreboot.org page) to connect the power jack to the board and connect the
-			AC adapter (without powering on the board).<br/>
-			Note: I ignored that advice, and wired up all 8 pins. And it worked.<br/>
-
-			Here is the pinout (correlate it with your programmer's documentation):<br/>
-			<img src="../images/t60_dev/0030.JPG" alt="" />

-			Connecting the pomona:<br/>
-			<img src="../images/t60_dev/0034.JPG" alt="" />
-		</p>

-		<p>
-			Connect programmer to 2nd computer:<br/>
-			<img src="../images/t60_dev/0035.JPG" alt="" />
-		</p>
-
-		<p>
-			Programmer has power:<br/>
-			<img src="../images/t60_dev/0036.JPG" alt="" />
+			Connect the pomona from the BBB to the flash chip. No pics unfortunately. (use the text diagram above).
 		</p>
 
 		<p>
-			Now flash the bricked machine using the 2nd computer. in my case I did:<br/>
-			<b>flashrom -p buspirate_spi:dev=/dev/ttyUSB0 -w bin/t60/libreboot_usqwerty.rom</b><br/>
-			Note: there are also other ROM images for T60<br/>
-			Note: this is using buspirate as the programmer, so it is flashing the T60, not the 2nd computer!<br/>
-			Here's my terminal window on the 2nd computer (also the programmer is active):<br/>
-			<img src="../images/t60_dev/0037.JPG" alt="" /> <img src="../images/t60_dev/0038.JPG" alt="" /><br/>
-			So, you should see the following:<br/>
-			--
+			SSH'd into the BBB:<br/>
+			# <b>./flashrom -p linux_spi:dev=/dev/spidev1.0,spispeed=512 -w yourrom.rom</b>
 		</p>
-			<pre>
-flashrom v0.9.5.2-r1517 on Linux 3.2.0-61-generic (i686), built with libpci 3.1.8, GCC 4.6.3, little endian
-flashrom is free software, get the source code at http://www.flashrom.org
-
-Calibrating delay loop... delay loop is unreliable, trying to continue OK.
-Found Macronix flash chip "MX25L1605" (2048 kB, SPI) on buspirate_spi.
-Reading old flash chip contents... done.
-Erasing and writing flash chip... Erase/write done.
-Verifying flash... VERIFIED. 
-</pre>
 		<p>
-			--<br/>
-			At the end it says "VERIFIED", which means that the procedure worked. If you see this, it means 
-			that you can put your T60 back together. So let's do that now.
+			It should be <b>Verifying flash... VERIFIED</b> at the end. If flashrom complains about multiple flash chip
+			definitions detected, then choose one of them following the instructions in the output.
