POST modules
• Page Deallocation Table Support—POST supports reading the page
deallocation table (PDT) and remapping memory if it detects a bad
page in the HPUX good-memory region. It updates all entries to
reflect the new memory layout if remapping occurs. It also clears PDT
if memory hardware change is detected.
• Client Boot—POST cleans up any residual state from POST
execution and boots the client specified in boot_module. POST can
boot clients with all processors or with just with the monarch
processor leaving the other processors in an idle loop.
