The workloads were increased for iV5R4 to better reflect common system load affecting the OS/400 portion of the IPL

Generally, the hardware phase is composed of C1xx xxxx, C3xx xxxx and C7xx xxxx on the 5xx systems. SLIC is composed of C200 xxxx and C600 xxxx. OS/400 is composed of C900 xxxx SRCs to the IBM i operating system console sign-on.
