Software Status Bulletin

Hitachi LC     M8227AA/BA Hitachi LC

Preface
-------------------------
This Software Status Bulletin (SSB) documents all known problems in the software
product designated above. The SSB is derived from Known Problem Reports (KPR)
which result from user problems that have been classified as documentation
problems or software defects. When a KPR is written, an identifying number is
assigned to it, and the KPR is added to the next edition of the SSB.

User inputs that have been classified as Enhancement Requests are not documented
in the SSB. User problems that have been submitted, but that have not been
classified by the time the SSB is generated are not included in the SSB.

How to use the SSB
-------------------------
When you experience a problem with a product, first check this SSB to see if the
problem has been reported already, and if there is a temporary workaround
available for the problem, or if the problem has already been fixed by a new
revision. If the problem is not listed in this SSB then you may wish to report
it to the Response Center or to your field support representative.

To determine if your problem is documented in this SSB, first look in the
Keyword Index section of the SSB. Under each keyword is a listing of one-line
descriptions of related KPRs. If any of these sound like yours, locate the KPR
# in the Known Problem Reports section of the SSB, and read the full KPR. The
KPRs in the Known Problem Reports section are sorted by KPR #.

There are two sections in the SSB:
Keyword Index: This index is categorized by keyword. For each KPR there is a
brief description and a KPR #. A KPR may be associated with more than one
keyword.

Known Problem Reports: This section contains KPRs, with all the available
information relevant to the problem. KPRs in this section are sorted by KPR #.
