no on both accounts unfortunately

No, I dont think so, it's pretty basic and 12 years old. I'll put some BIOS pics up shortly, see if you can see something I cannot., Thanks

I can boot from USB if the USB sticks have only memtest86 on them, BIOS seems perfectly happy to do that. When configured to Boot with UNRAID on them....nothing

Well the scandisk USB stick didn't work either Must just be some really annoying and illogical quirk. All memtest configured USB sticks boot in the new server None of those sticks configured with UNRAID will boot in the new server. But all of those usb sticks will boot other PC's into UNRAID. So annoying..!!

I've ordered a ScanDisk 16GB 2.0 in one last ditch attempt to see if this will try to be recognised to Boot. Failing that, the old hardware is going back in.....

all USB sticks are 2.0 and all headers are 2.0 / 1.1 only (no 3.0 in sight)

Hi, not sure if OP will see this but I am bit behind your curve and tried to migrate to: Intel core 2 quad - q9550 Gigabyte G33M-DS2R 8GB DDR2 RAM but my USB from even older hardware server wont attempt to boot at all - were there any strange BIOS settings or quirks to get the G33m to work?

I'm struggling here and need some assistance please. I've had a server running for 3 or 4 years mostly for Plex on old PC hardware. skt 775 Core2duo 4Gb Ram Gigabyte G31 mobo and all was well but I felt the need for more cores and more RAM. So a minor upgrade ensued... skt 775 core2 quad 8gb RAM and Gigabyte g33m board (not enormously different one would have thought!) However, The same USB stick wont boot or even start to. I've fiddled with every BIOS permutation I can see. It gets stuck at Verifying DMI Pool Data That USB stick in my PC starts to boot ok, can get to the Unraid menu choice screen. (so USB ok?) Different USB with memtest86 on boots in server OK (BIOS all set to boot from USB etc fine then) I noticed that Memtest86 configures file to FAT and Unraid USB file creator opts for FAT 32 so I manually created a USB drive with FAT put on UNraid and made it bootable - still no joy. I haven't changed my original USB stick as once I get the hardware read and boot I'm hoping to insert my original USB. I'm experimenting with fresh Unraid but cannot get it to even start to load. So I've tried a couple of other USB sticks (16GB Verbatim and 16Gb unbranded) and both work for memtest86 and neither work for Unraid as FAT or FAT32. I've tried with and without HDD attached, no change. In my searches, I've seen some people using same mobo and processor as me so it cant be grossly incompatible. Not sure what else to try and am open to suggestions........ Currently about 12 hours banging head against wall and counting TIA
