Firmware - BIOS vs. UEFI

Posted 07-22-2017 at 05:10 PM by hydrurga
Updated 08-07-2017 at 05:50 PM by hydrurga

A computer's firmware is low-level software, with an associated data area, that comes pre-installed in flash memory on the motherboard. The first software to be run when the computer is booted, firmware is generally customised to be motherboard-specific and designed to communicate with other hardware in the system. The two main firmware types used nowadays are BIOS and the more recent UEFI. This article does not cover other firmware interfaces such as libreboot and coreboot.

Machine Description

I have a six year old desktop machine from Pogo Linux (my hostname: "Pogo2011"). The machine has been running Ubuntu since it was new and is now at 16.04.2 LTS. The machine has an AMD Athlon(tm) II X3 450 Processor, 64 bit, 8 GB RAM, and two 500 GB SATA hard disks. One drive contains the OS and the other, my own data files.

RAMBOOT with continuous rsync synchronization

Posted 07-20-2017 at 11:55 AM by IsaacKuo

RAMBOOT is an initrd hack that loads the entire OS partition in RAM, making it run like an extremely fast SSD, at the expense of perhaps 1.5+GB of RAM.

Previously I described RAMBOOT using a compressed OS tarball. This is good for boot time, but it takes time to create a new tarball. This new How-To takes a different approach - simply copying an entire directory tree using piped tar commands (cp won't work because of the limited initrd environment). This increases boot time, but allows...

Computational Entropy

You may be wondering what has 'entropy' to do with Linux and more...
