Important notes
Processor speeds indicate the internal clock speed of the microprocessor; other
factors also affect application performance.
CD-ROM drive speeds list the variable read rate. Actual speeds vary and are often
less than the maximum possible.
When referring to processor storage, real and virtual storage, or channel volume,
KB stands for approximately 1000 bytes, MB stands for approximately 1 000 000
bytes, and GB stands for approximately 1 000 000 000 bytes.
When referring to hard disk drive capacity or communications volume, MB stands
for 1 000 000 bytes, and GB stands for 1 000 000 000 bytes. Total user-accessible
capacity may vary depending on operating environments.
Maximum internal hard disk drive capacities assume the replacement of any
standard hard disk drives and population of all hard disk drive bays with the largest
currently supported drives available from IBM.
Maximum memory may require replacement of the standard memory with an
optional memory module.
