# kevin: platform-specific notes
|
|
|
|
Early versions of ownerboot put the initramfs into the kernel image
|
|
using `CONFIG_INITRAMFS_SOURCE`. This would cause the boot process
|
|
to hang somewhere during the coreboot-to-Linux handoff process for
|
|
certain builds; the trigger seemed to have something to do with file
|
|
sizes. Overall it was not very reliable. Putting the initramfs in
|
|
the FIT image instead solved this problem.

# disassembly videos
|
|
|
|
- iFixit has a [photo guide](https://www.ifixit.com/Guide/Samsung+Chromebook+Plus+Battery+Replacement/101916) showing how to open the case and
|
|
also how to replace the battery. [This diagram](https://www.ifixit.com/Guide/How+to+disable+touchscreen+on+samsung+chromebook+plus/101905#s191207) (from a
|
|
different guide) shows the order to reinstall the back panel
|
|
screws for the best alignment results.
|
|
|
|
- [This video](https://youtube.com/watch?v=AW_6ZPhacgM) shows how to disassemble the laptop.

- [This diagram](https://www.ifixit.com/Guide/How+to+disable+touchscreen+on+samsung+chromebook+plus/101905#s191205) shows the location of some of the connectors.

# documentation
|
|
|
|
- The US FCC registration has [internal photos](https://fccid.io/A3LXE513C24/Internal-Photos/Internal-Photos-XE513C24-Rev1-3168065) of the board
|
|
components.

# improvements
|
|
|
|
- [@SolidHal's guide](https://github.com/SolidHal/Samsung_Chromebook_plus_v1_wifi_from_webcam) to transplanting blobless wifi chips into
|
|
your laptop. This looks scary but it's actually really easy.
|
|
|
|
- The [nanohub](https://muxtronics.nl/nanohub.html) is no longer manufactured so you'll need to
|
|
sacrifice your webcam in order to do this.
|
|
|
|
- You can completely remove the monitor cable (the cable that runs
|
|
*through* the hinge) from the laptop if you want; then you can
|
|
do all the splicing in a much roomier setting with no worries
|
|
about damaging other components. The disassembly video above
|
|
shows how (you don't need to remove the hinge).
