Re: Minimum load source size update

[DrFranken <midrange@xxxxxxxxxxxx>]

For IBM i 7.2 hosted disks the magic number is 37722 for the load 
source. This yields a perfect 35GB to the guest. Anything smaller will 
fail.

Must have full TR1 installed (Not just the MF99101) on the media you are 
installing from.

The 70G minimum for a physical disk is irrelevant because there are no 
available physical disks smaller than that for any server that supports 
IBM i 7.2!
