DSM 7.1 on ReadyNAS RN312?

[Zest]

Is it possible to install DSM 7.1 on ReadyNAS RN312? Is the platform powerful enough?

 

Platform: Netgear ReadyNAS RN312
CPU: Intel Atom CPU D2701, 2.13 GHz, 2 cores, 2 threads, microarchitecture: Saltwell (2011)
Closest match in Intel's public database is Atom D2700: https://www.intel.com/content/www/us/en/products/sku/59683/

Number of drives: 2
Memory: DDR3L, 4 GB, 1066 MHz 
BIOS: AMI v. 2.14.1219 (2011)
Other: HDMI out works.

 

I noticed that @Homeless managed get DSM 6.1 running on RN312:

 

Booting up plain TinyCore went fine on my RN312. Although I could not get the changed boot priority order to stick. After reboot RN312 forced the boot priority back to default. It's a bit unclear if @Homeless was able to make the new BIOS settings stick (with which changed BIOS settings?) or if the boot order was manually overridden on each boot.

 

I got quite confused by all the different loaders and DSM versions to choose from. Like this thread:

Which DSM version and loader would be the best for RN312?

The missing part for making the Boot Option Priorities in BIOS to stick was to also disable Floppy Drive BBS Priorities under Boot in BIOS.
