After that I replaced the memory with some spare SIMMs I had, put audio
and graphics back in and it seems to work. That is, it actually gets
to the boot menu. I didn't install IRIX yet, I have only 16MB of RAM.
I wonder why the original memory didn't work. It's IBM brand, marked
"11E8360BD-70 VJRX 32MB, 8M X 36 P". SIMMs from HP/9000 E25 don't work,
too, but that's expected.
Manual says
something about "dissonant piano chord" - how is it supposed
to sound like? One thing I've verified that without graphics card
the chord sounds the same.
It's an arpeggio of some sort, perhaps with a 7th. Haven't worked it out.
Getting the boot-tune means that much of the computer is working properly.
Try pulling the graphics and reseating the memory and processor module &
memory and see what pops out on TTY0. It could be bad graphics (had that
happen once in an Indigo), in which case there is a surfeit of XL/Express
graphics boards around (I have an Extreme that I haven't used for years). Do you know what the hardware is? Another possibility
is that someone tried
to upgrade the processor module beyond what the boot PROM could support.
Most of the time the machine will 'let it slide', but some cause issues
(especially if it's a R10k on a R4k board). If you don't know for certain
than describe: "module with a big aluminum heat sink and a small portion of
board exposed that has several SMD memory chips on it" can localize it to
one of 2 processor modules (R4400 in either 200MHz/2MB cache or R4400/250
with 2MB). Also give the IP number of the main board (it's near the riser
for the GIO/EISA cards), and the model number on the back
(CMNB007-something).
