My Sparc 1+ currently fails when booting linux. I get this

IDPROM: unknown format type!
program terminating

Is there a way to by pass the PROM?

The current PROM is a 525-1107-04 Can other sparc PROMS be
used as a replacement?

A note of success, my latest Apple ][ plus seems to have a
z80 card inside and the previous owner has also added the
extra ram, and internal fan and a RF converter for TV. IT
still has the original packaging and the game paddles.
