| Troubleshooting the IIfx |
Posted by: wood_e on 2008-12-30 07:11:54
Ok so I figured I'd take my conquest thread here.
Background:
I purchased this IIfx not knowing of its condition. No idea on how much RAM and no HD.
I plugged it in last night and got nothing, no chime, nada.
Remembering that these were picky about PRAM batteries I put two new fresh ones in. That made it power on... then I heard the death chimes.
I removed a bank of RAM and now it chimes properly - but i get no video to my Apple 13" "high resolution" monitor.
It has a Macintosh II video card in it.
I ordered another nubus video card off ebay so we'll see if that fixes it.
I also ordered an ATTO SCSI card and an ethernet card.
...To be continued...

Most ATTO SCSI cards are not bootable without modifications.

sounds like you are doing everything right... trying doing a pram reset.

Most ATTO SCSI cards are not bootable without modifications. oh man 🙁 bummer! What modifications do I need to do?

Is it SEIV? If so you need a beta firmware hack.

they are bootable with the latest stable firmware as well.

Did a little morre testing last night.
I noticed the IIfx has a riser for the ROM card from Spectrum engineering... what is this and is it necessary?

What is attached to the riser? A ROM card is essential, since there is no onboard ROM, and a riser may be expected to do something other than raise the ROM card.
An aside—prompted by curiosity—that I have to raise concerns jumpers on the MLB. How do they lie on your MLB?

Ok I'm going to post pics tonight.
I found the Q800 in 700 case that MacG4 sold me had a Radius Nubus card in it for video. Alas when I tried it I got no video from it.
I cleaned the motherboard throughly. and will try it tonight.

On a happy note I at least got it to boot tonight. Only one bank of RAM works (other bank might be bad). It has a lowly 4MB but on the plus side it DOES work!

Is that an overclocking device of some sort?
Spectrum Engineering rings a bell, oh yea they did the design for the Quadra 950 upgrade I have (68040/50mhz + 128K cache).

Look at the yellow writing on the top of the CPU.
So can you run a test program to see if anything runs faster? IS the RAM that works by chance faster then the ram that does not?

Yea that's just a overclocking device. Spectrum engineering evolved into newer tech I think.
This is pretty similar to the newer tech variable speed overdrive.
Not sure about this one, but with the VSO you can control the overclock in software which a nice feature that lets you find the stable limits of your system.

Huh - that's interesting. I wonder if i should remove it.
I think last night i tried the RAM that I believe to be faulty without that device as well - no dice.

So I'm going a little nuts with the paypal in my account and bought a motherboard with a video card and ethernet card off ebay. The best part was it had some huge RAM sticks on it.
Maybe I'll make a II into a IIfx with the spare mobo.

Ok...
I updated my SE IV card to version 2.1 firmware and now it doesn't boot the HD I have attached to it anymore. It booted with version 1.65 in my Quadra 700 (800) and now it isn't even recognized.
Any help would be lovely. I need to get this working in the IIfx.
