  Bugs: Known bugs are documented in Product Release Notes. The Support
  Advantage package (sent regularly to all customers on support)
  includes a Software Change Requests binder. SupportFolio Online
  (previously Advantage Online) (http://support.sgi.com/) 
  also lists SCRs. 

  Patches: a) Customers on support can get patches from the TAC. The TAC
  will tell you about a patch only if you report a bug which the patch
  fixes, but will give you a patch if you ask for it by number.  b)
  Support Advantage periodically includes a patch CD.  c) SupportFolio
  Online (http://support.sgi.com/) has lists of
  patches and the patches themselves.  SupportFolio Online is not as
  complete or current as the TAC, but is updated regularly.  d) Some
  patches (primarily for severe security problems) are in
  ftp://sgigate.sgi.com/Patches/. This is the only way in which you can
  legally get patches without being on support. Patches sometimes appear
  on sgigate before Advantage Online. e) Walter Roberson
  <roberson@hamer.ibd.nrc.ca> maintains his own lists of patches for
  several versions of IRIX, which he posts regularly to
  comp.sys.sgi.admin (see above under "network-accessible documents")
  and makes available via WWW (see above under "WWW pages").

  See also the article on patches in the Jul/Aug 1995 Pipeline, but
  note that it doesn't mention Advantage Online.

  Finally, the SGI FAQs mention many patches. Be aware that patches are
  superceded regularly. If you ask the TAC for a superceded patch,
  you'll be told about the patch which superceded it. SupportFolio Online
  has lists of superceded patches and the patches which superceded them.
