rEFInd-minimal - A stunningly clean theme for the rEFInd UEFI boot manager.

rEFInd is an easy to use boot manager for UEFI based systems. This is a clean and minimal theme for it. Locate your refind EFI directory. This is commonly /boot/EFI/refind though it will depend on where you mount your ESP and where rEFInd is installed. fdisk -l and mount may help.

Hackintosh-Installer-University - open source tutorial & information collector for hackintosh installation

•    Shell

📢 This is an open source tutorial & information collector for Hackintosh installations that does not charge readers any fee. 📢 We don't want to build a universal installation tutorial and, it's also impossible since every devices are different. We are here because we want to gather information and experiences, we want to build an index for most successful builds in github and make them be discovered more easily. When I was just a newbie, I didn't know how to get start building a hackintosh since I didn't know what's a bootloader and an EFI partition. It took me a really long time to find a helpful build in Github due to the deep location of that repo. So this is the purpose why we created this index.

yaota8266 - Yet another OTA solution for ESP8266, this time supporting large (>512KB) firmwares even on 1MB devices (repo is rebased)

•    C

yaota8266 is yet another bootloader/over-the-air (OTA) update solution for ESP8266 WiFi SoC. Unlike many other solutions, yaota8266 does not require reserving FlashROM space of 2x the size of the firmware. Instead, it updates the firmware in-place. Of course, this means that if an OTA update fails, there's no previous firmware to fallback to. On the other hand, if OTA update fails, you likely will repeat it again, until it succeeds. So, for many usecases the process of OTA update will be the same - a user will just repeat it until it succeeds, regardless whether there's a fallback firmware or not. yaota8266 is written with big firmwares and small flash sizes in mind. For example, it allows to have an OTA for full-fledged MicroPython (firmware sizes of 512+KB) on 1MB flash devices, and still have a small, but a filesystem.

efibootguard - Simple UEFI boot loader with support for safely switching between current and updated partition sets

•    C

A bootloader based on UEFI. For sending patches, please refer to the mailing list and CONTRIBUTING.md in the source tree.

toaru-nih - A completely-from-scratch hobby operating system: bootloader, kernel, drivers, C library, and userspace

•    C

ToaruOS-NIH is a distribution of ToaruOS which contains no third-party components. Its bootloader, kernel, modules, C library, and userspace applications are all written by the ToaruOS development team and direct contributors. This distribution aims to eventually replace the core of the mainline ToaruOS, with the various third-party components building against our own C library. This is a long-term project, and developing the C library to the point where it is useful for this purpose is not expected to be completed for quite some time.

Arduino_Boards - Board definitions for SparkFun-manufactured AVR, ARM, and ESP-based Arduino boards.
