Hi,

I was unable to get the obp upgrade to boot when put on a openbsd disk.  I guess,
but don't know for sure, that the sequence is:

- obp starts
- obp reads "something"
- something starts
- something reads the rest of the command line and reads the kernel.

This "something" doesn't read the obp upgrade.

If you compare the upgrade OBP with netboot to the diskless man page, the thing
loaded across the network via tftp when openbsd boots is ofwboot.net.  The thing
loaded with tftp is the actuall upgrade program of obp in that case.


cheers
