ZXnet http server: Note N00005: EISA Configuration Utility for Digital Alpha systems


Note Archive
Number: N00005
Created: 12 September 2007
Revised: 30 September 2007

Many Alpha-powered systems use the EISA bus for various low-speed legacy stuff such as the MFM controler (for floppy drives). The EISA bus must be reconfigured after erasing NVRAM, adding/removing ISA/EISA boards or when changing between OpenVMS/Digital UNIX and Windows NT. Rather than being included in ROM the software used to configure the EISA bus (the EISA Configuration Utility or ECU) is run off a floppy disk from the firmware.

Copyright notice from


The Eisa Configuration Utility (ECU) contains code which is
proprietary to Micro Computer Systems, Inc., and therfore is a royalty
bearing utility for them, and cannot be freely distributed.

If you have already purchased a copy of the ECU (or it came with your
system), you may order another copy or update as follows:

     Kit number (QA-01YAA-HC) is an orderable part number for
     customers who have already purchased hardware that included the
     ECU and licensing and need another copy of the ECU. Kit content:

         o  V1.9 (AK-Q2CRJ-CA) for OpenVMS and Digital UNIX

         o  V1.9 (AK-PYCJK-CA) for Windows NT

If you need a full copy of the ECU including the license, you may
order the following:

     Kit number (QC-01YAA-HC) is shipped with new hardware and
     includes the appropriate license sticker. Kit content:

         o  V1.9 (AK-Q2CRJ-CA) for OpenVMS and Digital UNIX

         o  V1.9 (AK-QF1GC-CA) for Windows NT

Where to get it and how to make use of it.

Some people have ignored the above and put it on the internet. These are normally in the form of a zip archive containing the files from the disk rather than a disk image. Most notes that come with the disk contents say the volume label of the floppy disk should be "SYSTEMCFG". So, just copy the contents of the archive to a blank floppy disk and set the volume label to SYSTEMCFG and it should work.
