Eric - My URL list in ADSM QuickFacts notes:

  3590
    Microcode:  ftp://service.boulder.ibm.com/storage/3590/code3590
                ftp://service.boulder.ibm.com/storage/3590/code3590/index.html
                (beware the index.html file being out of date!!)

If you check file dates in that directory, you'll see the latest files being
dated Nov 12 whereas the index.html file languishes at a May 2 date.
Buyer beware.
