+## Content
+
+There are 2 images:
+- Bottom 8 Mb image (IFD, GBE, IntelME, some BIOS)
+- Top 4 Mb image (continue of BIOS region)
+
+## Dumping a full ROM
+Concatenate bottom image with top image:
+`cat x230_lenovobios_bottom.rom x230_lenovobios_top.rom > x230_lenovobios.rom`
+You can try to unpack merged image to check if they were merged correctly.
+
+## Splitting the ROM
+To split the ROM into two images (one for the 8MiB and one for the 4 MiB flash IC), run the following commands:
+`dd of=x230_lenovobios_top.rom bs=1M if=x230_lenovobios.rom skip=8`
+`dd of=x230_lenovobios_bottom.rom bs=1M if=x230_lenovobios.rom count=8`
