Bios. Bios. Bios. Start - Etherboot/gPXE Wiki. gPXE is an open source (GPL) network bootloader.
It provides a direct replacement for proprietary PXE ROMs, with many extra features such as DNS, HTTP, iSCSI, etc. Take a look at our Screenshots page and the HowTo Guides for some ideas of what we can do, and grab the code from our Download page. Coreboot. Coreboot is an Open Source project aimed at replacing the proprietary BIOS (firmware) found in most computers. coreboot performs a little bit of hardware initialization and then executes additional boot logic, called a payload.
With the separation of hardware initialization and later boot logic, coreboot can scale from specialized applications that run directly from firmware, run operating systems in flash, load custom bootloaders, or implement firmware standards, like PC BIOS services or UEFI. This allows for systems to only include the features necessary in the target application, reducing the amount of code and flash space required. Flexibility in ROM: A Stackable Open Source BIOS.
