Disabling Secure Boot is a requirement to install INtime, the real time operating system that A3200 needs to run properly. A3200 versions 6.03 and above install with INtime 6.3 and require Secure Boot to be permanently disabled, there is no workaround for this. INtime 6.3 is not compatible with Secure Boot in Windows 10. If Secure Boot is enabled, an error will occur during A3200 installation. A3200 versions 6.02 and below install an older version of INtime and do not require Secure Boot to be disabled.  

See Optimizing A3200 Performance for more information on PC settings and how they affect the operation of A3200.
