This level of system firmware has been archived following the release of EL350_039. The EL350_039 Service Pack contains a fix to correct  a problem that prevented the system ports (integrated serial ports) from functioning.

Product/Development Engineering recommends:
1) If the EL350_038 is already installed and your system is not configured to use integrated serial ports you are not exposed to this issue there is no need to install the EL350_039.
2) If you are planning to upgrade to the EL350 Release Level, the EL350_039 (or higher) Service Pack should be used to eliminate any exposure to this issue.
