My understanding (which means I'm open to correction by people who _really_ know) is that z/VM 4 (which is the only version that implements Hipersockets) checks for an IEEE FPU, and loads a disabled wait if it doesn't find it. I am also made to understand that z/VM itself does not _use_ the IEEE FPU, so that if a usermod is created to disable that check, alternative vendors that support the features of the G5/G6 line but _not_ the FPU would be able to run z/VM 4. Those alternate vendors are adamant in saying they will not support that however.
So, bottom line, yes you need a G5/G5/z900 unless you're willing to bet your job on running an unsupported setup.

Guess that's why we couldn't get hipersockets in z/OS 1.2 to use the VM Guest Lan for the last few days ! Could anybody from IBM comment on the following questions:- a) any idea when these are likely to be available ? b) If "Hipersockets are implemented entirely in software" is there really a requirement to have a G5/G6/Multiprise 3000/z900 ??? ....Ian
