How this page was produced on the real machine - SINTRAN's own COLD-START/RESTART-SYSTEM code (PH-P2-OPPSTART.NPL, PL011) reads page 0, copies the fixed LOAD PROGRAM RELOA..LDEND (0300B = 192 words) plus the disc-type-specific swap driver (SWDSI = 1350B = 744 words) into it, patches the parameter words (KLIOX = IOX HDEV+4, KLHDE = HDEV, YSWTY, NOBLK, DYBLS, LDRAD, ADR2B, KLRC1, KBLSZ), and writes the page back.
