While setting up an Unraid NAS Server for file storage and virtual machine hosting I found that the USB drive was not showing up in the UEFI BIOS Boot Priority drop downs. This was confusing because when I manually selected the boot with F12 the USB device showed up. I found a helpful reddit post… Continue reading Alienware USB Boot Priority
In a previous post, I went over how to set up powerlevel9k in your terminal using ZSH shell found below. https://teaandtechtime.com/its-over-9000-zsh-theme-installation/ But there is a new way of getting things done! PowerLevel10k is out and better than ever. The prompt is faster and the configuration is easier. A link to the new Github repo is… Continue reading Powerlevel10k Upgrade
