General Comments

 * Report by Pete
 * He reported that he installed ArcaOS 5.1 on a dual boot configuration with Windows 11. CSM needs to be enabled to boot from CD/DVD on this system.
 * Installed 5.1.0 in UEFI Boot mode to GPT disk layout
 * Note About Hyper Threading:
 * The AMD's version of Hyper Threading is called Simultaneous Multithreading (SMT) which can be Disabled in:
 * BIOS -> Settings -> Advanced -> AMD Overclocking -> Manual CPU Overclocking -> CPU Core Count Control -> SMT Control [Auto] or [Disable]
 * Pete have been using this mainboard with SMT set to Auto, resulting in ArcaOS reporting "Processors Intialized: 12" for his 6 core Ryzen 5 5600G CPU during boot for over 3 months and the system has been very stable. He did "Disable SMT" in the BIOS but did not see a lot of difference in system speed in general although Seamonkey and OpenOffice apps seemed to start just a little quicker when SMT is set to Auto so he reset SMT to Auto.
 * The NVMe drive makes for a very fast boot and applications start more quickly.
