The system (by default) links and accesses the CF1 disk as its A-disk and the CF2 disk as its B-disk during IPL - when it loads the CPLOAD MODULE, and reads in and processes the SYSTEM CONFIG file. It also reads some other files at IPL, and some as-needed (e.g. LOGO files).
See the CP Commands.manual for CPREL and CPACC commands (off the top of my head - names may be slightly different). Mike Walter Aon Corporation Sent from the wee keyboard of a Blackberry.
