ASUS archive of 1.18 MB labelled TSIC, with no model or board number in the name. TSICT is the name of an ASUS service tool used to view boardview data in its own format, so this package most likely holds that viewer or files for it, though only the contents can confirm which. Technicians use such tools to locate parts, follow nets and find test points on ASUS mainboards. Scan the archive before running anything, and match any board data inside to the PCB number and revision on the actual board.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @boardview_software_download. Enginerys does not host this file.
