Ask HN: What are good resources to learn how a computer boots? I have a basic understanding on how boot works, but I'm interested in having a better landscape about BIOS, ACPI, drivers, and OS (Linux preferably) boot up process. I found myself debugging on dmesg, ie. why my battery drains more than usual on S3 sleep state, and I realize I don't know what's the actual flow and responsibilities of each piece. |
