6 GB Hard Disk

[Mauro73]

Hi,

is there a way to make a 6 GB Hard Disk work on my A4000?

I mean, now I have this HD with no data inside (but it work perfectly because I've tested it on my PC) and I wish to use it with the Amiga.

I never thought there was much to do other than connecting it up and doing up the formatting.

IIRC, here is what I used with large HDD (120Gb) on A1200&A4000 builtin IDE:

-setpatch from OS3.9
-pfs3(ds)

and thats it!
I think that OS3.9 setpatch worked with WB3.1

Ok but I'm supposed to run OS 3.9 first and how do I do this if the only hard disk I have is this empty 6GB one?

Well, this is true for a PC or a Macintosh, not for the standard IDE controller into the A4000.

just extract the setpatch command.. it may need few additional files.
you should have a boot floppy with all that, pfs3ds, pfsformat and hdinsttools.

Load Amigados onto a partition that sits *BELOW* the first 2GIG.

That way the 4000 will load the standard FFS operating system, load the Patches and other needed stuff to be able to read/write safely past the 2GIG barrier.

Ok I've done the trick. Now I have a 1.5GB partition with OS3.1 installed. I've installed idefix97 to see my dvd-rom and then I've created the Emergency-Disk from the OS3.9 CD (because the one coming from Amiga Kit doesnt work).

I'm going to start an installation and tell you how it goes.

Thank you very much  :-)

Yes you also need the AmigaOS ROM Update in DEVS:. Without this, setpatch will run but won't patch scsi.device to make it save to write above 4GB.

If you have OS3.9, the safest way is just to install it. That way you can be sure your >4GB access is working properly.

I can't understand this os rom thing, but I'm installing os 3.9 right now (I've formatted the disk in three 2GIG partitions with the os3.9 install cd before).

I'll let you know how it will end up  :-)

OS3.9 has its own version of Kickstart. But it's not on a chip, it's in the form of a file on hard disk. Setpatch applies this update on cold boot so that your Amiga is running Kickstart 3.9, which includes an updated scsi.device which is safe to use above 4GB.

But you don't really need to know that. I was really just pointing out that if you're trying to hack OS3.9 features in to OS3.1, then it's not as simple as copying Setpatch. If you're actually installing OS3.9 in full then don't worry - it will take care of all of this stuff for you.

Thank you for the explanation, now I understand: it's an operation similar to the one that relokick does, isnt'it?

Anyway, I've installed wb 3.9 and everything works fine now.
Now I'm installing programs and utilities... so, I'm pretty happy for now  :-)

Thanks again dudes  :-D

I would imagine the principle is the same. It softkicks the 3.9 updates and Kickstart is then accessed from RAM.

One thing... did you re-partition your hard disk after booting from the Emergency Disk? If not then your partition is still using the 3.1 version of FFS, which cannot write above 4GB.

Yes, I did three x 2GIG partitions just before installing the whole 3.9 Os.
