Intel Processor N95 Alder Lake-N CPU shows up in entry-level mini PC with 2.5GbE, dual HDMI

We’ve started to see Intel Alder Lake-N processors in mini PCs such MSI Cubi ADL N and Morefine M9 based on announced SKUs, but the Intel Processor N95 processor, which Intel has yet to unveil, is now found in a mini PC sold for various Aliexpress sellers starting at $187 for a barebone system and going up to $384 for a model with 32GB RAM and a 1TB SSD preloaded with an activation version of Windows 10 or Windows 11. The Processor N95 is a quad-core processor clocked at up to 3.4 GHz (Turbo) with 6MB cache, and 16EU Intel UHD graphics clocked up to 1.2 GHz. The 15W processor’s base frequency is shown to be 1.7 GHz in GeekBench while the 6W Alder Lake-N processors have a sub-GHz base frequency. That could mean the CPU performance is quite higher than the 6W N100 and N200 parts, but the GPU […]

U-boot now supports booting Linux from an HTTP server

Up until now, U-boot would only support the User datagram protocol (UDP) allowing for TFTP and NFS boot, but Linaro has now added support for TCP and HTTP in U-boot in order to boot Linux from common web servers. TFTP boot from U-boot has been supported for years, as around the year 2006 I remember implementing TFTP Linux boot for a Karaoke system in order to lower the BoM cost by selecting a smaller flash device, and I also explained how to boot Linux on a TV box with TFTP back in 2014. This requires installing a TFTP server on your server, which is quite a trivial task, but HTTP servers are omnipresent, so it’s a welcome addition to U-boot. If you want to use HTTP to boot Linux, it needs to be enabled in the U-boot config:

CONFIG_PROT_TCP=y
CONFIG_PROT_TCP_SACK=y
CONFIG_CMD_WGET=y

CONFIG_PROT_TCP=y

CONFIG_PROT_TCP_SACK=y

CONFIG_CMD_WGET=y

The top and bottom options are pretty obvious, and the second […]

TerraMaster F4-423 review – A low-power 4-bay NAS tested with Unraid

Hey Karl here. The timing couldn’t have been more opportune when I was asked to review the TerraMaster F4-423 4-bay NAS. Let me explain why. I run Unraid as my OS of choice for my home lab. I have found it easy to maintain and hard to break. My old rig had a 3900X with 3 cores, 6 threads dedicated to docker containers, and the remaining cores running VM’s. It has been a fun and learning experience. I have run it with several different VM configurations over the past few years. The majority of the time I ran 2 VM’s. One personal and one work and I would RDP over to the work VM. If I wanted to game I had a third gaming VM and allocated all resources to it. It’s not super convenient and as convoluted as it sounds. But recently I moved back to my company-provided laptop […]
