I don't know where you got the information, but there is no problem in
upgrading the graphics in an R3k Indigo. The process has nothing to do
with the PROM. Yes, you will need to get a new graphics boardset -
Express graphics (XS,XS-24,XS-24Z, XZ,& Elan, Elan is the best) is
completely different architecture than the Entry. Note the only
difference between the versions of the Express is add-ons to the base
GR2 board - VM1 video RAM f. 24-bit color,ZB4 Z-buffer,GE7 geometry
engine chips (1 f. XS,XS-24,XS-24Z, 2 on XZ, 4 on Elan); these could
be bought later to put onto the board but are going to be hard to
find, best to just buy an Elan. Also note that in upgrading the
graphics hardware you'll also need to upgrade the graphics drivers in
IRIX. Search your favorite USENET archive of comp.sgi.* for details -
it's pretty easy to do it...
I don't know about any video options for Indigo (I vaguely recall that
there was such a board, but was quite rare), but audio I/O is already
provided from the processor board....
