Title: Dual CF adapter in A1200?

Can a dual CF adapter work in an A1200 or is it only the singel adapter that will work. In other words, does the idefix contain any specially clever amiga spesific hardware?

Also, if I use a CF card, I guess that I won't be able to read it on a PC CF card reader since it will contain a RDB and an Amiga file system?

I've used the same compact flash card on windows and mac without any trouble. I don't see why there would be any kind of special platform dependent file system on there. Mac likes to put a .trashes file in every directory, though. :-/

I was thinking that since I don't have network on my a1220 that I could put files on the cf using my pc, and then plug it in the adapter?

But thinking harder about it made me worried that it might not work like I'd planned/hoped... :)

WinUAE can read/write RDB,CF card reader,CF pcmcia adp. or harddrive .

 AFAIK, using the CF cards on Amiga only works with just one CF on the IDE chain. The Amiga simply refuses to boot if a CD-ROM (marked as slave) is connected.

 Maybe two CF could work, if the problem lies in the speed of response of old firmware devices (like CD and HDs).

I once used to have external hard disk and CD-ROM drives, connected to the A1200's IDE port with a (not so) long cable, and they worked fine: hard drive as master, CD-ROM as slave.

You can read the card in winuea if you want.

I got a dual CF adapter in my A1200/030 works great and it boots first time every time.
256mb with AmigaSYS3PlusAGA,WhdLoad and iGame installed.And a 4gb Full with WhdLoad Games. :-D

 I still use the internal HD and an external DVD in my setup. What I was saying is the Amiga refuses to boot with a CF card as master and another device as slave. But with two CF seems to work ok.

 That's caused by differences in response time, I guess.

So please excuse me, I hadn't understood.
That is strange, must be related to the way IDE is implemented on the Amiga.

FUD, aka: lies.

Mac OS X, not Mac (that's a computer) puts the .Trash folder/drawer/directory at the root of the each volume/partition/disk so your precious "undelete" will work, when you mistakenly delete a file that you shouldn't have.

What Mac OS X does put in every folder/drawer/directory is the file .DS_Store, which stores the state of the view used in Finder (view = icon mode, or list mode, or browser mode).

it's also used as the term for the platform...

So it's like a .info file, essentially.

Indeed. Except AFAIK only Mac OS X exhibits this behaviour, therefore it doesn't apply to the platform.

:-) Tiger... hehehe. Good one! I was actually writing it in a very non-chalant way, but I do get ticked off with the exhibited misinformation about Mac OS in general.

As for the 'like .info', it's not so. Because the .info contains file metadata. The .DS_Store (which like the .Trash is safe to delete any time you want, as long as you realize what you're deleting), basically saves or contains the settings for the views. For example, if I select icon view (so that I see the thumbnails of a directory), and then enlarge those icons to 128x128 pixels, that setting will take effect every time you open said folder, as long as .DS_Store exists in there. If you delete it, then the default Finder setting takes effect, which is icon view but I think closer to 48x48 pixels for each icon.


PS. Sorry for high-jacking what seems a completed thread, but ignorance is not bliss, it's mental poverty, and facts are facts, and knowledge is information and information is mental power.

i think os 9 did the same.

...which is clearly not enough:

EDIT:
And a helpful tip for disabling .DS_Store files on network stores:

I was surprised when  this (http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&rd=1&item=200179141056&ssPageName=STRK:MEWA:IT&ih=010) didn't sell (btw it's not mine).  It seems to have a dual CF card.

I would be surprised as well, but you know now... as the seller was obviously a pirate (since he's including 3 DVDs of games), and Amiga buyers are ethical people, they just refused to buy it!


OK, in all truth the fine print says what happened: "The seller ended this listing early because the item is no longer available for sale. This item or one like it has been relisted." Which probably means the seller and buyer agreed on a Buy It Now and finished off the deal nice and quick.

And now the thread is back on topic, all with factual info, and no FUD, yay! Let's go get some 2xCF adapters now!

EDIT:
And to add something pertinent and useful, check the DMA compliance of your CF card:
