Many thanks to all of you for the excellent work and thread but especially @Tasso, @Chanh and @Kith!
First, I bought a few Intel DN2800MT boards to build a server and a dedicated player. Apologies if these questions have been asked before. The Intel boards have two mini PCIe slots and a PCIe slot. Has anyone used a microSD card adapter to a miniPCIe slot rather than an SSD for the Snakeoil OS? The Intel boards have no obvious way to use a Cfast card.
Second, I bought an Elfidelity USB Isolation card - this works really well with the Intel board with a default clock speed of HPET. However I'm trying to compare it an existing streamer using a Gigabyte GA-N3150. For some reason the default clock speed used by Snakeoil for that board is TSC and HPET isn't an option. Does anyone know why that is? Thanks in advance!
