So I just got everything in for my NetBoot setup. Here’s what I’m currently using:

Naomi 1 mobo + Multi Region H BIOS
NetDIMM 256MB w/ null key + firmware 4.02
Mitsurugi’s Maple Board adapter
ATX PSU (450W) + adapter cable

I don’t have anything connected to the network port yet, but I have a pi I plan on using when I can get the netdimm working.

Anywho, when I turn the Naomi on without a cartridge, I can verify that video is working (haven’t hooked up sound yet), and that I get error 01 which seems pretty normal so far.

When I connect the netdimm board, I start getting ERROR 22. As far as I can tell from my searches, this can either be remedied by setting the correct jumpers on the board and/or by cleaning the contacts/reseating the board. I’ve done both (the latter several times), but to no avail.

What else could I be checking/doing?

UPDATE: a friend told me to reseat the “inner” board of the dimm. I tried that, with only a minor change. Now when the NAOMI boots, the 4 LEDs next to the network port flash a specific pattern (R = red, G = green, N = no light)

wait about 10 seconds

Error 22 is related to up board from Dimm that is not with good connection.
