Anyone who read the Initialization and tuning reference: <quote> IHAPCCA When a CPU is brought online, the location of its PCCA is determined by which list includes IHAPCCA. If neither of the lists includes IHAPCCA, the PCCA is in 31-bit virtual storage. If both lists include IHAPCCA, the resulting location is undocumented. The PCCA of the IPL CPU is built in 24-bit storage before DIAGxx is processed. If additional CPUs are brought online later in the IPL process, the IPL CPU is automatically configured offline and back online, with its PCCA located according to the CBLOC specification. </quote> -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
