For some reason, I took the chance of exploring 6.9 with U-boot firmware because this is the first time I successfully installed OpenBSD without a serial TTY console (with keyboard and monitor only) were with 6.7 and 6.8 it's a no go and then I observed that it's temperature is quite calm, favorable and regulated as compared to using UEFI which is very very hot. Though I stumbled with RTC not working. Thanks and best regards, Archimedes
