Hi!
Im trying to setup my CF card for my Amiga 1200. I have followed Johnim`s great guides to setup CWB OS3.9 and to format my CF card with SFS filesystem. Now everything is working great in Winuae, but when I put the card in the Amiga it will not boot and give me a black screen:blink:
Anyone have an idea of what can be wrong?
Maby this is a silly question, but Im pretty new with the Amiga software:)

My hardware is:
Amiga 1200, Blizzard 1230mk4 with 64mb ram, 32GB Sandisk CF card.

Hi!

How large is your system partition? It needs to be within the first 4gb and ideally smaller like 512mb.

I think you also need to patch the SCSI device as you're using a 32gb CF, (again I think don't quote me) that OS3.9 supports only 8gb drives by default.

I'm only using 4gb CF's here and all my IDE HDD's are on real SCSI chains without the 4gb limitation.

All the best,

Steve.
 
The boot partition is the first one and is 600mb, and the scsi device version is 43.43. I do have a 4GB card that works fine, I just wanted to try my 32GB for fun:)

scsi.device 43.43 isn't enough for system to recognize you partitions >4GB.
Load Doobrey's scsi.device 44.2 via LoadModule and you'll be fine.

If you use OS3.9 then you'll also need to exclude the loaded scsi.device from BB2's update file by changing setpatch declaration like this:
C:SetPatch SKIPROMMODULES "scsi.device" QUIET
 
Thanks for the tips Mfilos:) I will try Doobrey's scsi.device 44.2.
The last ting you said I didnt understand.. Do I need to write this in the startup-sequence?:blink:
Will try this before I try another card:)

Ok let me clarify what I meant a bit better :)

Since you have OS3.9 with BoingBag2 installed, there is a file in DEVS named "AmigaOS ROM Update". This file has inside all the BB2 ROM modules that are loaded in boot by SetPatch.
Since you're gonna load Doobrey's scsi.device with LoadModule, running SetPatch without any option will load the BB2 update file and will try and load the scsi.device 43.43 as well.
Since a scsi.device would be already loaded (44.2 by LoadModule) into RAM, system will tell you that scsi.device is already loaded and will stop the booting process.

In order to avoid that, you tell SetPatch to skip loading scsi.device from the BB2 update file with the following declaration:
Code: 
C:SetPatch SKIPROMMODULES "scsi.device" QUIET

So... all newer ROM modules will load just fine except the scsi.device which will load by your earlier declaration :)
 
hi mfilos mate could you do a little guide for this so it can be added to my guide
 
There's aren't much things to write my friend :S

In order to use a newer scsi.device you just need the new scsi.device (lets say for example in DEVS folder) plus LoadModule tool from Aminet (lets say for example in C folder).

Once you have those ready:
1. You just need the following declaration first thing into your Startup-Sequence:
Code: 
C:LoadModule Devs:scsi.device

2. You need to comment your existing SetPatch declaration (by putting a semicolon in front of the SetPatch command - like ;SetPatch.....) and then issue the following declaration instead:
Code: 
C:SetPatch SKIPROMMODULES "scsi.device" QUIET

That's all... you're set :)
 
I have benn working on this for a while now, but I can not get the machine to boot for some reason:huh: Have tried with a 8GB and 32GB card. Everything is working fine on my 4GB card though, so I think I will use this for now. Thanks for the help anyway:)

Maybe your CF isn't compatible with the Amiga.
Not all are.
