Appendix B. Product warranty and notices 133Important notesProcessor speeds indicate the internal clock speed of the microprocessor; otherfactors also affect application performance.Maximum memory may require replacement of standard memory with optionalmaximum memory module.When referring to processor storage, real and virtual storage, or channel volume, KBstands for approximately 1000 bytes, MB stands for approximately 1000000 bytes,and GB stands for approximately 1000000000 bytes.When referring to hard disk drive capacity or communications volume, MB stands for1000000 bytes, and GB stands for 1000000000 bytes. Total user-accessible capacitymay vary depending on operating environments.CD-ROM speeds list variable read rate. Actual speeds vary and are often less thanthe maximum possible.Maximum internal hard disk drive capacities assume the replacement of any standardhard disk drives and population of all hard disk drive bays with the largest currentlysupported drives available from IBM.IBM makes no representation or warranties regarding non-IBM products and servicesthat are ServerProven, including but not limited to the implied warranties ofmerchantability and fitness for particular purpose.
