• IBM service and support is available for
• 9672 Ri6 and 9672 Ri7 ("G5" and "G6")
• 2064 Models 101-116 and 1C1-1C9 ("G7")
• Multiprise 3000^®
• LINUX also runs on
• 9672 Ri4, 9672 Ri5 ("G3", "G4")
• Multiprise 2000^®
• P/390, R/390, Integrated Server
• These machines may not be supported by middleware and other products

• ECKD^TM 3380 or 3390 DASDs
• FBA (9336, VDISK in storage)
• Expanded Storage


• Tape Devices
• all models of IBM 3480 Magnetical Tape Subsystem and 100% compatibles
• all models of IBM 3490 Magnetical Tape Subsystem and 100% compatibles


• Network devices
• Virtual CTC
• Real CTC
• LCS: OSA 2: Token Ring, Ethernet, Fast Ethernet
• LCS: OSA-Express: Ethernet, Fast Ethernet
• LCS: 2216: Token Ring, Ethernet
• QDIO: OSA-Express: Gigabit Ethernet, Fast Ethernet
• 3172
• IUCV


• Channel devices
• ESCON^® connections
• FICON^TM(not tested)
• Parallel Channels


• Character devices
• 3215 console
• Integrated Console


• IPL mechanisms
• 3480 and 3490 tape units
• VM reader
• DASD
• Load from CD-ROM (HMC) or FTP-Server on G5 or newer with recent SE-level


• Root file systems during IPL
• Initial RAM disk
• VM minidisk
• DASD
• NFS (only via CTC or IUCV)


• Linkage
• ELF linkage

• Hardware requirements
  • An S/390 or zSeries configuration with a recommended 64MB of memory (absolute minimum 16MB)
  • ESA/390 Basic Mode, S/390 LPAR or VM guest
  • ESAME Basic Mode, ESAME LPAR or z/VM guest for 64 bit
  • Under VM: a minidisk (recommended 500 Cylinders) or a dedicated ECKD DASD (3380 or 3390)
  • For native: ECKD DASD (3380 or 3390), 3390 Model 3 recommended
  • Temporary access to a tape unit for install
• Software requirements
  • A network connection (TCP/IP) to that OS, to transfer LINUX for S/390 to the system
  • If you want to use LINUX under VM APARs VM62520 and VM62573 should be applied. For VM TCP/IP PQ37002 should be applied.
  • If you want to use the IEEE hardware FPU, ensure you have APARs VM62337 and VM62410 installed before bringing up Linux under VM. Anyone IPL-ing Linux under VM/ESA V2R3.0 will need VM61762, too. It already exists in the 2.4.0 base.
  • If you want to use TCP/IP for VM/ESA, it is recommended that you install APAR PQ34318.
  • Following MCF is needed to run LCS on Multiprise 3000:
