Hello, I have been having a lot of issues, but I think I have worked through all of them except the core. I had Unraid (6.9.2) running on an old Gigabyte Z77X-UD5H motherboard computer I build in 2012 but ultimately decided to return that to my main windows machine and migrate the drives to something specific for Unraid. I found an R520 on ebay. when it arrived I powered it on, and everything seemed to have worked. I downloaded the full package of firmware and bios updates from Dell and successfully installed. I however am unable to boot from the usb drive. I get a "This is not a bootable disk. Please insert a bootable floppy and press any key to try again." I also tried UEFI boot, but found the same memory load problem which everyone is apparently clear cannot be overcome, so I have remained in BIOS mode. Concerned about the possibility that the drive failed somehow, I plugged the thumb drive back into the Gigabyte computer (without moving the drives back) and confirmed it boots right up. I have tried placing the usb on the front and back of the R520 but it seems to make no difference. I have seen a supposed "legacy bios" boot option, but I cannot find it. Does anyone know something about how I can proceed, or find out what may be bad in this machine? Everything seems to be operating as it would expect except this. Thank you, Eric

trurl, thank you, the current bios is S5000.86B.12.00.0098.062320091136 and was updated June of 2009, I cannot seem to find an upgrade for this. Squid, yes, I gathered as much. What I am wondering is should I give up on this motherboard and use something slightly newer? maybe use the case and periferals and source a used motherboard off ebay.

Perhaps not doing enough research thinking that my requirements are relatively low, instead of purchasing a Synology NAS, I opted to use an old Intel server I had and build an unraid system. I can find documents now though that it may have been too old back in the early '10s. What I have: Intel S5000psl which has 2 Sata ports and 4 SAS/Sata ports. My system was working with two 8TB Seagate Ironwolf drives to the SATA ports, I moved all my documents I had kept in network shares on my windows PC, and verified I had copied everything over. Then I began adding the additional drives from my windows machine which it no longer needed. I added 2x Samsung SSD 256 GB cache drives which worked, but which show an error "Probable ATA device behind a SAT layer: Try an additional '-d ata' or '-d sat' arguement" I didn't think much of it, and with the cache I was seeing 120MBps transfer speeds from my other wired machines to the unraid server. Then I added 2x 4TB Seagate Ironwolf drives to the SAS/SATA ports which then only showed 2.2TB available each. I am concerned that if I use these drives with only 2.2TB I will lose data if I eventually connect it somewhere which can see all 4TB, is this accurate? Should I buy an expansion card with additional SATA ports, or should I just scrap the whole thing? File transfers have seemed to be fast enough, but I have not gotten into my Jellyfin server which is now giving "playback error this client isn't compatible with the media and the server isn't sending a compatible media format" errors on media which had no problem from my windows machine network share folder. Perhaps a newer motherboard in this case? Probably what I am really looking for is people to say "scrap it" and some advise how best to use the equipment I have to minimize cost in getting something set up. Thank you!
