[NAME] , yes, the T5810 is nvme bootable via pcie adapter card.  Since you don't plan to use raid, don't waste money on a $100 Dell ultraspeed adapter, a cheap $7 adapter should work (I use a $12 adapter with dual nvme and heatsinks).  If you only have a single graphic card on slot 2 then you should have 2 more slots available, it's a pcie wired as 8 on slot 1,  and one pcie x16 on slot 4.  If you still plan to use 2 nvme on the same adapter then look for the Dell dual nvme adapter, it's cheaper, around $50 last time I looked.  Part number DPWC300. Cheers,
Hi. I have a t5810 with A34 bios. I have not purchased anything yet but I need to know if I get a dell ultraspeed adapter to run 4 nvme drives can I boot from one using uefi?  Initially I will only be using a single 1Tb intel 665p nvme drive I'd like to boot from. And eventually I will add 2 drives for a tiered storage pool. I have searched hard for a definitive answer about boot from this card and I need someone to tell me that they boot from a nvme drive without some workaround. I know all about fresh installs and the install will be in uefi with sata set to ahci. I am not looking to use any raid. Like I said eventually I will be using storage space direct with server 2016 data center and tiered storage but not for a month or so. Thanks, Rob
