Is the Unraid Boot menu code available anywhere? I am interested in making the changes that would make the Unraid Boot Menu UEFI aware and handle memtest entry accordingly. Most of the work appears to be in the GUI code for maintaining the syslinux entries, but some small changes need to be made to the Boot Menu in UEFI and Legacy mode to handle the memtest part of it differently in the two cases.
IF you already have such a work package in hand then great, but if not I am prepared to offer my services to work on it.
