You wrote a boot rom, which is usually embedded onto the motherboard of a synology.
The main OS is installed and then copied onto every sata drive you add.
I'm in the same boat, picking up my N54l today bought on eBay last week for €160.
At the same time I ordered a super cheap usb3 card, £6 from china. If it works great if not it can go in my PC.
I'll post on here my results .
I´m picking my N54l up later this afternoon from the f*ç#ing useless courier company that tried to deliver it on tuesday but couldnt be bother to leave a note in my postbox. Well done MRW and welcome to Spain.
Anyway i think I´m going to try the 5 beta on the included 250 gig drive and see how that goes but i will probably use the 4.3 on the 3x3tb drives i ordered when then arrive. I also ordered a really cheap usb3 card from ebay so that will go in when i get a chance to help with external backups. It sort of feels like Christmas all over again but this time I´m getting stuff i actually want.
