Install Debian 11 on ReadyNas 526x

It's been a while, and I haven't had ample time to process things. However, I had the opportunity to buy a ReadyNAS 424 (~150 USD with 2x4TB disks 🙂 ) and tested the manual above on it. Here are some conclusions:

1. There is no need for the USB daughter board; you can disconnect it (and return it to stock when selling).

2. It can boot from an M.2 SATA disk (mine is 128GB).
3. Of course, initially, you have to boot from USB disk (this can be changed in the BIOS).
4. The RN424 has no ability to connect an external video card, so UART was used (worked fine - link how to do it above).
5. When the system is installed and there is no daughter card in it, you can switch to boot from the M.2 disk, and it stays that way... (in contrast, when USB is selected as the boot device, after a restart, it returns to the initial setup).
6. Finally, I was able to install Debian 12 and OMV 7 on it. So far, it works fine. I’m waiting to do the same with my 526x.

this is how to extend live of our "not supported" readynas 🙂 

stay tuned 😉
