Uhh, yeah. NVRAM. It's damn difficult to shove the Sparc 5 EPROM into
an Ultra 5... A friend calling the NVRAM a "PROM" has tainted me into
calling it that, I guess.
No idea on the jumper. When I've tried it (putting the NVRAM into an
Ultra 1 / Ultra 5), it Just Works.
Anyways, you shouldn't ever need to replace the Flash chip on a U5/U10,
unless you need to replace more motherboard bits as well. It's
"resistent" to being flashed incorrectly (high/low halves). Still I
guess you could erase both halves at once if you tried. I personally
try to keep my foot out of my orifaces. :)
