## Boot Optimization

While EDKII BIOS is used for
[specific image versions of Edge Microvisor Toolkit](#edge-microvisor-toolkit-image-versions),
you can try [Slim Bootloader (SBL)](https://github.com/slimbootloader/slimbootloader)
\- an open-source boot firmware that can optimize and accelerate the boot
performance of your device.

SBL is designed to run on Intel x86 architecture. It is highly optimized, secure,
and lightweight at the same time. Slim Bootloader supports modular payload
architecture and can support UEFI through UEFI-payload. SBL provides a viable
option for customers who prefer to develop their own boot firmware for their
platforms.

Switching to SBL and enabling fast boot will result in a noticeable speed-up.
Refer to the
[official documentation](https://slimbootloader.github.io/introduction/index.html)
for more details. Visit the
[GitHub page](https://github.com/slimbootloader/slimbootloader)
for deployment instructions and full source code.
