Chapter 12. Software for IBM iSeries and
AS/400e systems
IBM OS/400 Version 5, Version 4, and some Version 3 releases (specifically OS/400 V3R7
and V3R6) support reduced instruction set computing (RISC)-based processors. OS/400
V5R2 supports all RISC processors except the 5xx and 4xx models. This chapter covers the
OS/400 and related software information for all software releases supporting the RISC
processors documented in this IBM Redpaper.
OS/400 software releases up to and including V3R2 run only on CISC models of the AS/400
system (Bx0, Cx0, Dx0, Exx, Fx0, P0x, 100, 135, 140, 2x0, and 3x0 Models). For information
about software supporting these CISC systems, refer to AS/400 CISC System Builder,
REDP-0042.
OS/400 software releases from V3R6 and V3R7 through V5R2 run on the Model 150, 4xx,
5xx, 6xx AS/400e systems. For information about software supporting these RISC systems,
refer to AS/400e RISC System Builder, REDP-0342.

840, 270, SB2, SB3, 250, 720, 730, 740, 150, 620, 630, 640, 50S, 53S, 500, 510, 530, 4x0,
and Sx0.
