This upload contains quite a few DEC/Compaq/HP Alpha firmware update CDs. These CDs were posted on their FTP and sometimes bundled with Tru64/OpenVMS installation CDs to update Alpha systems to the latest firmware.
At some point around version 5.7 or 6.0, firmware update CDs quit including firmware updates for earlier models. Therefore one has to check the smmtable.txt file on later CDs to see which CD has which firmware versions. Even older versions of the CD won't read normally under Windows at least when I tried mounting them, they might work in an emulator with Tru64 or VMS however.
The older versions of the firmware are included for preservation purposes.
