The EB164, like all of the Alpha Evaluation Boards built by Digital contains the Evaluation Board Debug Monitor and so this is available to load Milo (Section E.5.2 Loading from the Debug Monitor). Quite often (although not always) boards whose design is derived from these include the Debug Monitor also. Usually, these boards include the Windows NT ARC firmware (Section E.5.1 booting from Windows NT ARC firmware). The SRM console is also available (Section E.5.5 Loading Milo from the SRM Console). A flash management utility, runnable from Milo is available so that once Milo is running, it can be blown into flash (Section E.7 running the flash management utility). This system supports Milo environment variables.
These systems have several boot images in flash controlled by jumpers. The two jumper bank is J1 and is located at the bottom of the board on the left (if the Alpha chip is at the top). You select between the boot options (and Milo when it is been put into flash) using a combination of jumpers and a boot option which is saved in the NVRAM of the TOY clock.
Jumper SP-11 of J1 in means boot the image described by the boot option. Jumper SP-11 of J1 out means boot the Evaluation Board Debug Monitor.
Blowing an image into flash via the Evaluation Board Debug Monitor is exactly the same proceedure as for the AlphaPC64 (Section E.5.6 AlphaPC64).
