- 100% Free Software (GPL), no royalties, no license fees!
- Fast boot times (3 seconds from power-on to Linux console)
- Avoids the need for a slow, buggy, proprietary BIOS
- Runs in 32-Bit protected mode almost from the start
- Written in C, contains virtually no assembly code
- Supports a wide variety of hardware and payloads
- Further features: netboot, serial console, remote flashing, ...
- Some BIOSes don't enable hardware virtualization features (AMD / Intel), thus you cannot use that feature of your hardware (e.g. for XEN, KVM, etc).
- Some BIOSes don't enable HPET (can be used by Linux for enhanced power-saving features, e.g. on laptops), see linuxpowertop.org.
All of this is (or can be) fixed in LinuxBIOS, as it's open source. With a proprietary BIOS you're dependant on the good-will of the vendor to fix these issues.
Some anecdotes where LinuxBIOS saved the day
- The "Press F1 to continue" error on a cluster (without a single keyboard attached).
- Improved Fan control behaviour: http://www.linuxbios.org/pipermail/linuxbios/2007-May/021049.html
