+Subject: [PATCH 3/3] dell_inspiron_1100_unpacker: Add module type 0x52
+
+The module with type 0x52 in the Latitude E6400 BIOS is the EC firmware,
+and is not compressed. The current behavior tries to decompress this
+module leading to an index out of bounds error at runtime, so add a new
+condition to avoid decompressing it. This assumes type 0x52 is always
+used for EC firmware.
+
+The current behavior also assumes all the data before the first module
+is EC firmware, which was probably true for the Inspiron 1100, but for
+the E6400 the EC firmware is in module 0x52. However, for simplicity an
+exception is not made for this behavior, so the extracted EC.bin should
+just be treated as spurious data for the E6400.
+
+TEST: Inspiron 1100 BIOS is still unpacked correctly, Latitude E6400
+BIOS unpacks without runtime errors.
