The wiki is being retired!
Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to https://doc.coreboot.org/. Contributions welcome!
$ mkdir foo $ cd foo $ wget http://www.memtest.org/download/4.20/memtest86+-4.20.tar.gz $ tar xfvz memtest86+-4.20.tar.gz $ cd memtest86+-4.20
(Optional: edit config.h and set #define SERIAL_CONSOLE_DEFAULT 1 for serial support)
The file memtest is your final payload which you can use with coreboot, either on real hardware or in a QEMU image.
Finally, you have to build coreboot with Memtest86+ as payload:
$ cd .. $ svn co svn://coreboot.org/coreboot/trunk coreboot $ cp memtest86+-4.20/memtest coreboot/payload.elf $ cd coreboot $ make menuconfig
Now enter the Payload menu and select Payload type and then An ELF executable payload file. Then, exit the menu, save your settings, and build coreboot:
The file build/coreboot.rom is your final coreboot image, which also contains the payload.
