With the release of the mobos featuring 5GB ETH or better, some having ONLY 5GB+, the current image for the ISO is outdated. There is no support for the new breed of network card as the kernel used on the ISO is too old. Also, creating an ISO from scratch (WinPE or otherwise) can be quite time consuming for people not used to the process and prone with errors.
A new boot ISO with Trixie should be created to help future proof the ISO and keep entry level of UrBackup low.
