* Base cover
Its [Hardware Maintenance Manual](https://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/x230s_hmm_en_0c10860_01.pdf) could be used as a guidance of disassembly.
The SPI flash chip (W25Q128.V in thr form of SOIC-8 for mine) is located at the circled place. Unlike [most Ivy Bridge ThinkPads](Ivy_Bridge_series.md), X230s has a single 16MiB SPI flash chip.
The general [flashing tutorial](../../flash_tutorial/index.md) has more details.
