disable_ram_warning

#!/bin/sh

# Disables invalid memory notifications on Synology NAS (including the notifications in DiskStation itself)
# these warnings occur when you use perfectly compatible RAM, which is not Synology branded
#
# Modify `MANUFACTURER` and `DBFILE` to match your environment (DBFILE will be the filename of the .db in DBPATH)
# Use Synology Task Scheduler to run it on boot, as root user
# Finally run `sudo ~/disable_ram_warning' 

# This script is safe to run repeatedly, and will also work if Synology update DiskStation later, and make additions to the db file
