Install Debian 11 on ReadyNas 526x

[Grogu]

As there are growing issues with Debian 8.x on ReadyNas ( see : https://community.netgear.com/t5/New-ReadyNAS-Users-General/ReadyNAS-628X-KEYEXPIRED-amp-Hash-Sum-mi...

I decided to try this manual

https://community.netgear.com/t5/New-ReadyNAS-Users-General/Tutorial-How-to-install-your-own-Linux-O...

to run Debian 11 with Open Media Vault ( https://www.openmediavault.org/ )

however I have some doubts with :

label CentosFlash

kernel x/vmlinuz

append initrd=x/initrd.img inst.vnc inst.vncpassword=password inst.headless ip=dhcp inst.stage2=hd:LABEL=CENTOS-8-1 nomodeset

Above is strictly for CentOs and I'm wondering how it should look like for Debian 11 , anyone can help ?

The Debian installer does not have VNC built-in.  I assume that he chose Centos in part because it does.  For Debian, you could use preseeding (https://wiki.debian.org/DebianInstaller/Preseed) and then SSH in once it's installed to add VNC if you choose to use it instead of just SSH.

Not sure if I can install OMV on CentOs (I assume not)  thus wonderin if I may connect via PCIe with video card to interact with Debian as here ( in japanese however google transtaors is good enough 🙂 ) :

Thank you for your reply !

On a 526x, I believe you can.  I've never had my hands on one, but the photo of the rear looks like it has a PCI slot.  But most ReadyNAS do not have a PCI slot, so not everyone could follow your lead.

Ok, I've just recieved connector (PCIe x16 >> PCIe x1) and was able to enter to 526x BIOS settings with my video card, and after pluging in USB I was able to select this USB as boot thus it seems that I'll be able to start with Debian installer from this USB. 

Prior any changes I need to backup all my data 🙂

Have a look here for a detailed guide to installing OMV7 on a RN526X/RN626X:

A serial console via the Micro-USB port is way more convenient than installing a PCIe graphics card (which is fully possible on these units as a temporary solution. You cannot mount the GFX card permanently due to the offset position of the PCIe slot)
