OK, so, it doesn't exactly "work". I think I may be hitting a PROM
weirdness.
What's happening is that the PROM loads arcload, arcload then loads
its config file, then the kernel, all fine. But when loading the
initrd, the PROM returns a file size of 0 bytes.
A network trace shows the PROM throwing back a TFTP error to the
server after the second block of data.
I tried loading the initrd image directly from the PROM prompt (which
very obviously isn't going to get me very far as it's not an
executable of any kind) and the network trace shows exactly the same
error being thrown back to the TFTP server at exactly the same point
in the transfer.
It looks like the PROM is peeking at the file and stopping the
transfer if it doesn't like what it gets, though I have a hard time
believing that.
As the kernel image is loaded flawlessly, this is for sure not an
ARCLoad issue (same code used).
I know the PROM is a bit of a mystery for everybody, but can anyone
offer any hindsight?
JB.
