A4000D with Warp Engine 060

[Drgonzo]

Hi all,

First post and hoping for some sage advice. I recently got back into the Amiga after many years away. I came across a lot which included an A4000D with a warp 040 which is now (indirectly thanks to Cosmo I'm told), an 060 Warp Engine with a 75 MHz rev4 060. As expected, due to the FPU it's not very stable. I'd done a ton of research and understand my stock (and legal) 3.1 ROM needs an exec.library update for the system to work right. I'm on the fence about buying the Cloanto 3.x rom kit since I'd like to keep the workbench.lib in the rom for max stockness. Same for going to 1MB ROM. I tried to cook my own 3.1 with just a new exec.lib and it seemed to all fit and compile, but booting winuae with it is hit/miss. When it does boot the version does check out. I've been trying to get my 4000 soft kicked with it to test, but none of the kickers seem to work. Warpkick, skick, rekick, etc... Skick keeps telling me there's no ram to load it into. Is that because all I have is 32bit ram on the WE? Or because the WE says it doesn't support MAPROM? I'd thought about buying an eprom kit but I'd like to know if my cooked rom is good and hardware viable before I make the further investment. If I do break down and buy Cloanto 3.x, can anyone confirm that it should be stable with my setup?

Full specs:
A4000D
WE w/Cosmo adapter and rev 4 060 @75 MHz
128 MB on WE
16 GB SD card via IDE adapter
IDE CDROM
Picasso II
OS 3.9

Possibly will install my Prometheus once the rest is stable and see about locating a Voodoo 3 card ��

Thanks in advance for any help!

You need proper patched ROMs for your pimped WarpEngine to work properly. And you also need the correct 060 libraries installed in Workbench to enable all the 060 features.

I've got mine patched roms for warpengine 4040->4060 from user stachu100, ask him for help

 

[Drgonzo]

Hello and thanks for your response. I'm aware of the need for the patched roms, but am hoping to be able to test a modified rom using a soft kicker before I buy eproms and a programmer. So far I've been unsuccessful.

Thanks again,
G

Thanks Misha! I will do that.

Much appreciated!

Resurrecting an old thread as I've moved the needle a bit. I have a patched 3.1 Kickstart now but have been struggling to get things stable. If I go back to a clean load with the 040 then all works fine. With the 060 I can boot but get software errors of varying degrees based on the several different combinations of 040/060 libs I try. Can anyone recommend versions of the libs I need to track down? Seems like every post I find has a different suggestion.

Thanks in advance!

I have a similar system where I use the libraries that come with MMULib (http://aminet.net/package/util/libs/MMULib).

From my side no problem whatsoever with 060 rev6@80MHz.
Which 060 rev are you using and on what frequency?

 

[Drgonzo]

I tried installing the MMULib from Aminet, but each time I try a fresh install it renders the machine unbootable with some strange message on boot about a string being too long and it just stops dead at a cli prompt. I did a little chasing down through the startup sequence but wasn't able to find the culprit. I'll refresh the thing again though and see if I can get a grab of the message.

Regarding the proc, it's a 68060rc75 rev 4 running at 80 MHz. I know optimally I'd want the 6, but haven't found a source yet that's reasonable/reliable. I believe it not being and LC or EC should be remedied by the patched kickstart with updated exec.library, right?

Thx,
~G

Problem found.
Please use 060 rev6 with patched KS.

I'd agree. There are no 75Mhz-marked 'full' 68060's - only re-badged knock-offs.

Only the last Rev 4 'EC/LC' parts ever got that speed marking. CPU060 will tell you your PCR value and ID the internals of that '75' marked chip.

Real Rev 6 68060's are seen with 'RC50' endings, even though most have good overclock potential.

 

[Drgonzo]

Ok, so actually pulled some strings and got a rev 6 68060RC50, dropped it in, and sure as **** it does seem more stable. Everything I'd read (or thought I'd read) was around the 006 being good at overclocking and preferable, but had thought earlier revs would at least function... and in theory a low over clock on a rev 4 from 75->80 MHz would be better than a rev 6 50->80 MHz.

I'm going to give it a fresh 3.9 load with the mmulibs tonight and see how things go. I put a small heat sink and fan on it. Am I likely ok with overclocking that much, or should I really try to find a lower oscillator and shoot for something safer like 66 MHz?

Thanks for all the help, finally seeing a light at the end of the tunnel. Now just need to get it recapped, close it up, and I'm livin' the dream! ��
