Revisiting this ....

Although the 'ARM710' option can indeed be used with the latest RISC OS 
5 disc image, networking doesn't then work with that image. An ip 
address, netmask, route etc can be assigned but no external connectivity 

The only apparent error when setting up networking is that in the 'Host 
names' dialog box, only the 'Host name' textbox is editable (the 
nameserver boxes are greyed out) and the 'Reset now' button doesn't work 
in the final dialog box.

Networking works with the RISC OS 3.7 Uniboot setup, but 'ARM710' does not.

So, my question is, as the only configuration setting that works here 
with Uniboot is 'StrongARM',  is RPCemu meant to be fully compatible 
with 'ARM710' and RISC OS 3.7? If so, how do I achieve it?

Using different versions of BootVars does not resolve the issue. I tried 
the newer version from the RISC OS 5 disc image (5.33 I think) and I 
can't find any versions older than the one included in Uniboot (5.0).
