Memtest86+

Building

Memtest86+

$ 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)

$ make

The file memtest is your final payload which you can use with coreboot, either on real hardware or in a QEMU image.

coreboot

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:

$ make

The file build/coreboot.rom is your final coreboot image, which also contains the payload.
