 +==== U-Boot 1.1.4 modification for routers ====
 +Forum member [[https://forum.openwrt.org/profile.php?id=72549|pepe2k]] made a modification of **U-Boot 1.1.4** for **Qualcomm Atheros** SoCs based devices (the project is still being developed, so new devices and SoCs will be supported in the future). Up to date information, binary images and sources can be found on official [[https://github.com/pepe2k/u-boot_mod|GitHub repository]].
 +
 +This modification started from [[http://code.google.com/p/wr703n-uboot-with-web-failsafe/|wr703n-uboot-with-web-failsafe]] project, but supports more devices, all modern web browsers, has a lot of improvements and other modifications (like U-Boot NetConsole, custom commands, overclocking possibilities etc.).
