  • 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 LCS, 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
  • zSeries Basic Mode, zSeries 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 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:
    EC Stream F34643 MCL048
  • For OSA Express under VM, you need APAR VM63034.
    For HiperSockets under VM, you need APAR VM62938 and VM63034.
