Hi @sakuraime ,
I search this from Google, but did not find more details description of these columns.
I found an old blog, this take an example page header dump from DBCC PAGE. This function is similar sys.dm_db_page_info.
This stores a number of different flags that describe the page. For example, 0x200 means that the page has a page checksum on it (as our example page does) and 0x100 means the page has torn-page protection on it.
Hope this could help you.
