If the information above is true making the changes below to consinit()
in arc/arc/machdep.cshould cause the display to light up,HOWEVERI
remember trying this a year ago and it didn't work. (Maybe something
else was broken so it wasn't a valid test)
========== new machdep.c==========================
case NEC_R96:
#if NVGA_ISA > 0 > 0
if (vga_isa_cnattach(&arc_bus_io, &arc_bus_mem)
== 0) {
#if NPCKBC_JAZZIO > 0
pckbc_cnattach(&pica_bus, PICA_SYS_KBD,
JAZZIO_KBCMDP, PCKBC_KBD_SLOT);
#endif
return;
}
#endif
break;
============== original machdep.c ====================
case NEC_R96:
/* XXX - some machines have jazz, and others have
vga */
#if NPC_PICA > 0
pccnattach();
return;
#endif
#if NVGA_JAZZIO > 0
if (vga_jazzio_cnattach() == 0) {
#if NPCKBC_JAZZIO > 0
pckbc_cnattach(&pica_bus, PICA_SYS_KBD,
JAZZIO_KBCMDP, PCKBC_KBD_SLOT);
#endif
return;
}
#endif
#if NRASDISPLAY_JAZZIO > 0
if (rasdisplay_jazzio_cnattach()) {
#if NPCKBC_JAZZIO > 0
pckbc_cnattach(&pica_bus, PICA_SYS_KBD,
JAZZIO_KBCMDP, PCKBC_KBD_SLOT);
#endif
return;
}
#endif
break;
