Shouldn't be. It's just forth code manipulating the device tree. Doesn't
do anything exotic with the processor. On the other hand, it does need
to have the client interface initialized, which happens automatically
during startup. If you're somehow bypassing that, you'd expect to have

heh. I certainly can't send you one, Oracle is much more retentive on
exporting code than Sun ever was.
However, if you have hardware, you've got the binary. My recollection is
that older versions of Solaris (pre Solaris-10) just leave the prom
mapped in kernel space, starting at 0xf020.0000 . If not, you'll have to
figure out how to use /dev/physmem to map in the prom so you can dump it
Another possibility is the version of Openboot that was opensourced by
Sun several years ago - 4.21, I think. See:
