+# Configuration for HP Z220 CMT
+#
+#The board supports Intel LGA1155, which allows for ME removal (both neuter+disable as claimed by me_cleaner),
+#ME region resize/shrinking (aka 'maximized' board), as well as VSCC table modification.
+#In this respect it is similar to the ASUS P8Z77 motherboards, but comes with the bonus of ECC RAM compatibility.
+#
+#The blob download script uses the manufacturer supplied ME and IFD and performs the necessary 
+#hashing. The download script also removes the VSCC table by overwriting a NULL at the VSCC 
+#length table and FF bytes at the VSCC identifier table - using a printf with dd
+#and resizes the rom layout and minimizes ME while maximizing space.
+#The Computer comes as standard with an 16MB Flash chip, which means that no modification is 
+#needed to replace the chip is order to use heads as we shrink ME and 'maximize' this board by 
+#default. It is soldered onto the board, as is the TPM1 chip.
+#
+#Test platform
+#BOARD: HP Z220 CMT
+#RAM: 16GB - 2x ATP DDR3 ECC
+#CPU: Intel E3-1275v2
+#Even though this has been tested with a discrete graphics card installed, like on other Sandy/Ivy Bridge boards Heads is configured to use the iGPU, i.e. to get a display output while running Heads please
+#avoid the 1230, 1270v2, etc in favour of 1245v2, 2600k etc.
