I’ve tried using the installed ZimaOS and have installed an HDD in the first expansion slot. I tell it to restart and it appears to go into sleep mode or similar. Acts like it is going to restart and seems to go into a sleep or standby mode. The only way I’ve been able to get it to come back on is removing and reconnecting the power cord.
Semi-related question, how many of the drive bays are bootable? Bay 1, HDD with Win11 is recognized and bootable. Bay 2, HDD with Win10 powers on and is seen when Win11 is running however doesn’t apear as a bootable option.
