If you are planning to run Linux on a standard Alpha based system, then there are pre-built "standard" MILO images that you might use. The original images (along with the sources and other interesting stuff) can be found in gatekeeper.dec.com/pub/Digital/Linux-Alpha/Miniloader.
The images subdirectory contains a directory per standard system (eg AlphaPC64) with MILO images having the following naming convention:
MILO - Miniloader executable image, this image can be loaded in a variety of ways,
fmu.gz - Flash management utility,
MILO.dd - Boot block floppy disk image. These should be written using rawrite.exe or dd on Linux.
The test-images, like the images subdirectory contains a directory per standard system. These images are somewhat experimental but tend to contain all the latest features.
Digital/Compaq is no longer doing any work on MILO itself. However several people have picked up where Compaq left off.
Stefan Reinauer has done the work to get MILO to build against the 2.2 series of kernels. His work is available from http://www.freiburg.linux.de/~stepan/Milo and is mirrored by AlphaLinux.Org at ftp://ftp.alphalinux.org/pub/Linux-Alpha/Miniloader/v2.2.
Nikita Schmidt has updated the existing MILO source to provide support for the changes in the ext2 filesystem, as well as adding in many other bug fixes and patches. His version are available from ftp://genie.ucd.ie/pub/alpha/milo.
