Who knows the answer to how it works? There are such parameters in linux kernel loader options: linux /zImage ...... syno_hdd_detect=18,179,176,175,177,171 syno_hdd_enable=21,20,19,9,173,172 HDDs will not spin up without these parameters. So, what do these numbers mean? How is this implemented? Synology added some custom options in the linux kernel? Is there a way to emulate these parameters for my custom kernel, or spin up the HDDs in another way? Thanks

Hi, I'm working on running a clean version of BSD/linux on Synology hardware, namely DS620slim. It's a 6-wide box based on Intel Apollo Lake platform. Overall successful, now I have a FreeBSD 13-CURRENT running on DS620slim, but there are several problems: 1) All 6 AHCI channels visible, but no power on SATA drives. As I undestand, in DSM some driver (or service?) can manage disks power, which one? Power management is implemented through the i2c bus, or am I wrong? Is there any sources of this software? 2) No PWM and LEDs driver - the status led is always blinking, the fan is always running full speed. What driver does this in DSM? 3) UART console does not work. Similarly, no Intel PCI-UART driver in FreeBSD. :( In general, the 2nd and 3rd problems are not so important, the main thing is to understand how to manage the power of the disks so that they spin up. Thanks for advices
