Hi All, thanks for the useful information. I have an old Toshiba Satellite which using the 3615 boot and pat succesfully loaded. I'm currently on the Crytical updates for the 6.1.7 DSM version. I'm not sure how should i update or apply those and most important, the link (https://xpenology.com/forum/topic/7294-links-to-dsm-and-critical-updates/) shows 3 updates, all of them with the same name. Should i run all of them or just the third one?. thanks in advance. Any help would be greatly appreciated.
