oke lets do a test, you will need a a usb stick, be aware all data on that usb stick will be erased.
Attached a program called Rufus version 3.9.1624. This program we will use to write an iso file to the usb stick and make it bootable.
The rufus program can be started by unpacking the archive and clicking on the exe file.
First put the usb stick in an usb port of your pc.
Start rufus
Select your usb stick in case you have more then one usb disk attached, otherwise the usb stick should already be selected automatic by rufus.
In the boot selection it will mention disk or ISO-image (select) ,
Press the select button and select the iso file we are going to write to the usb stick (fvdw-sl-i686-check-16apr20.iso)
Leave everything else default (no changes)
click start,
a window pops up download required regarding grub 2.02 versus 2.04 , select "no" (do not download)
a window pops up with message ISOhybrid detected
choose write in dd-image-modus
warning window pops up about that all data on usb will be erased (in case usb is not empty)
choose ok
windows pops up more then 1 partition on disk (in case multiple partitions are present and that they will be lost included data inside)
choose ok
Now partitions will be removed and image is written to disk
ready, remove usb stick and close rufus
Put the usb stick in a usb port of your nas en boot the nas. The nas must be connected to your LAN.
If everything goes well the nas will boot a minimal linux system with a webserver.
You can use the fvdw-sl assistant to find the ip of the nas an connect to webinterface
In your web browser window a text like this should be visible in case boot was successful
$matches[2]
Post the hardware ID it shows we will need later to activate the beta firmware.
Pressing the "terminate" button in your web browser will shutdown your nas and you can remove the usb stick.
I know you have a 64 bits nas but the i686 kernel will also run on a 64 bits cpu
