Are the exact machine type and models2. Have the same BIOS level3. Have the same adapters/attachments in thesame locations4. Have the same addressjumpers/terminators/cabling5. Have the same software versions and levels6. Have the same Reference/Diagnostics Diskette(version)7. Have the same configuration options set in thesystem8. Have the same setup for the operation systemcontrol filesComparing the configuration and software set-upbetween “working and non-working” systems will oftenlead to problem resolution.NoticesReferences in this publication to IBM products, programs,or services do not imply that IBM intends to make theseavailable in all countries in which IBM operates.
