@Geoman,

No I don't own the Aptiva anymore. It fell down some stairs during transport and was damaged beyond repair. I salvaged the CPU, memory, cache, and other parts, but the frame itself was warped. So to the scrapyard it went. Too bad, since I got the computer for free when I purchased two Compaq Ipaq computers from somebody in the city where I live. The guy worked for Cisco, and he had a pretty impressive network installation at home. Enough hardware for a small business. Anyway, he sold me the two Ipaq's (60 Euros total) and then threw in the Aptiva and a Pentium 75 computer in for free. I wanted to use the Aptiva for a mod, but soon gave up that idea since the case was so different.

I still have the COAST cache chip. (256 Kb, asynchronous). If you can put it to use in your Aptiva, I'll be happy to send it to you. Don't know whether it will fit your particular board thigh, IBM made an alarming number of different versions.

Yes, these boards are very picky concerning the caches...

There it is:

Thanks to Twix I now have got a perfectly working cache module inside the Aptiva:

The riser-board makes the difference
The Aptiva is well designed, indeed

Btw. Alliance still produces the cache-chips:

The riser board ... Leave it out or unpowered and the Aptiva doesn't boot. What does that remind you of?

@twix: I dont now... well actually this particular aptiva runs w/o riser board perfectly - I flashed it to the newest bios version and this is the cause... ??

@miod: thanks! ^^

You never know with things like that... my O2 was not supposed to boot without the PCI riser and it has no problems if you remove it. I found it the other day, when I was upgrading the CPU .

C-E: ah you reminded me of what twix meant with his hint:

Yes, an O2 needs the riser board to boot - at least they say so. I never tried to power it on without one...

Mine works perfectly fine, but I did not try to connect it to internet before putting the riser back

So I upgraded the Aptiva some months ago with a Kingston Petium 233MHz MMX - module and a new harddrive. Great for all MS-DOS apps. Runs even GLQuake in 1280x1024 under Windows NT smoothly.

Cool! What's next? SSD drives?

PCI P/390 works with PC Server 325, yes. But you have to run OS/2.

I actually thought about that, but then I got myself for the Aptiva a new old stock Maxtor 2B020H1 (replaces the used-up 540MB Maxtor with FRU-number) from eBay. Silent and fast.

The very last thing one could do is to get another one of this precious cache modules and 128MB EDO RAM...
