Flashing PROM

This was for an Origin 200 but may be applicable to other systems too.

1) When the POD prompt appears, type "go cac" to enter cached mode.
2) At the Cac> prompt enter "pcfg v"; note the PROM version displayed for both the master and slave, they should be identical. Sometimes when the PROM is corrupted the version shows up as 0.0. Also note the NASID of the slave (probably 1)
3) Enter "flash" followed by the NASID number; this should copy the master's PROM image over to the slave if the PROM is healthy enough.
4) When (if) the POD prompt comes back, enter "reset" to reboot.
