My own experience with ACA 630/25MHz

I'm not sure of that either. I was under the impression that you can kick having a 3.0+ kickstart but I might be wrong on that one.

You better ask AmigaKit or FOL instead

I am formulating this as neutral as possible:

You can load and map ANY rom image from harddisk as your new Amiga operating system. Once it is loaded and mapped, it stays reset-proof and works like you just have swapped the rom chip in your computer. Plus, it's executed from very fast SDRAM.


acatune -maprom <romfile> >NIL:


Where <romfile> is the filename, including full path, on your harddisc. It works on ALL ACA's and both Kickstart 2.x and 3.x.

Enjoy.

Nice, i'm gonna try that out this weekend i think... would be nice if i can run os 3.1 without getting a new rom

I've had some time to try out my board a bit.
But i have a lot of problems with whdload games.
Anything that you've experienced as well?

A few small games works, but a lot of others don't
I'm using the same cf card as i've been using in my a500 (68020) with 4 mb fast mem and 0.5 mb chip, kick 2.05.

Most of the games works on the a500. but not the a600.

Any ideas?

I dont mean to hijack the thread, just wanted to hear about your experience with it

What is your MaxTransfer set to?

i don't actually remember for this card, since it's the first i ever formatted.

But the os and most of the non whdload works fine.

Wouldn't it have an influence on that too?

Max transfer will cause problems loading bigger files, i.e the larger WHDLoad games, when you said the smaller games work I thought this could be the first thing to check.

Also this problem is more to do with the IDE on the A600/A1200 so I doubt whatever HDD solution you used on the A500 was affected.

I think its best to re-do the CF card from scratch for the A600 (or another CF) and use MaxTransfer 0x1FE00

When you enter this value you must press enter or it will not be saved.

Mapping ROM3.1 from HDD is a very nice idea, I must try it, so the iBrowse and other 3.0+ applications should work? Thats awesome!

I don't see why they wouldn't. MiamiDX and IBrowse both work on my A600 with 3.1Rom

Have a look at AWeb as well, it isn't a bad browser.

[Nikolaj_sofus]

Ok, i'll give it a try.
what about SFS, would that work with os 2.1?
Might be the better solution and save me a couple of headaches in the future.

Why use OS2.1? Your ACA630 can re-kick 3.1Rom so why not use OS3.1? (or even 3.9 if you're brave!) I'm not sure if you can use SFS with OS2.1 but I know it needs at least an 020 processor, of course your ACA has better however if you want to disable the ACA then your 68k fallback would not be compatible.

You could look as PFS3 which supports both or just stick with FFS, I'm using FFS on my A600 and its doing a great job, 2mb/sec off the IDE with my Apollo 620

I understand him, I would also keep OS2 in my A600 if it would be possible, just because OS2 simply belongs to Amiga 600 in my opinion. But unfotrunatelly it prevents me to use jabber / web browser, so I will probably switch to OS3 as well.

With a 68000 and just Fast Ram for sure I agree stick with OS2.1 but if you've gone and stuck this rocket of an ACA630 in then as you say for the apps that take advantage of the 030 you're going to need a more up to date OS...

[Nikolaj_sofus]

ok... think that i'm gonna try to reformat with FFS and the correct settings.

Even though i shouldn't have to with whdload, it would be nice to be able to disable the ACA in case i want to play some old games which does not agree with the 030 cpu.

What about the maprom option?
I got kickstart 3.1 on my a1200, but i do not own a 3.1 rom for my a600 or 500. Are there even a way how i can aquire a 3.1 rom image for my a600 legaly?

Otherwise i don't see a reason for not changing the rom physically on the mainboard.
Even if i wanna do a dual boot with fallback to os 2.1, i guess the 3.1 rom shouldn't cause a problem.

[Twiggy]

I have OS3.1 running on my A600 (which really has an 2.0 ROM in it) using WinUAE to set it up and adding the maprom line to it (after installing ACATune), works fine.

You could buy the Rom and dump the Image, I'm not sure if its part of Amiga forever, I doubt it being less common...

Anyway I doubt anyone will string you up if you get the Rom from another source

Otherwise i don't see a reason for not changing the rom physically on the mainboard.

I've never tried, but I imagine there could be a chance of things not being compatible. You could install a Rom switch if you were worried about that and wanted the real roms installed.

I guess it's legal if you are running not more than one Amiga with 3.1-kick (either in ROM or from HDD) at the same time.

Eeerrrmmm, and if so, does it really matter?

Enjoy.

Damn, I added ACAtune -maprom dh0:Kickstart3.1 >NIL: as the first row to my startup-sequence, where acatune is in DH0:C, Kickstart (rev40.63, 524288 bytes) is in the root of DH0: and after reset there is a black screen and Amiga doesn't boot. If I reset it again, I get a green screen (chipmem fail I think), then black and thats all. Unfortunatelly I can't even remove the first row from startup-sequence, because it is not possible to boot my Amiga without startup-sequence - I can't get into early startup even if I turn off and the on my computer. I will have to try to boot from Workbench floppy probably.
