Hi!
Thanks for the answer. I had tried that before (read it in the docs) but I choose "Keep old" in stead No wonder would not work. Problem solved now (I'm typing this on the A4000 now)

I'm sorry, but i don't see a thing

The HD is in the bottom cage, but i don't see the ACARD.
I must admit i still don't know if the bridge is plugged
right into the HD or if a cable goes from the HD to the
bridge and further?

Is it done like that?

Ah, come on, now you left me completely puzzled

Please, answer the following question with a simple YES or NO

An IDE HD connected via an Acard Bridge adapter to the UWSCSI controller that resides on the CyberstormPPC does DMA?

Hmm.. if I use IDE HD with Acard's 68pin adapter with CSPPC UWSCSI, it doesn't do DMA?

With my not-so-scientific measures, it would seem it does - cpu usage is low and transfer rates comparable to fast, native uwscsi drives.

Very cool.

I've never seen a demo of OS4 on the 1200 before -- not as fast as on an A1, but not bad at all.

Wonder whose system that was?

Thanks

Anyone know of a place which sells UWSCSI drives for a decent price?
Or do i have to pay outrageous 200 Euros up to get one?
Then i'll better to stick to some my SCSI-II drive.

SCSI-ADAPTER INTERN DB68HP BU / IDC50 BU
SCSI III / SCA ADAPTER
No information, only the pics...the last one is a SCSIIII and thus out of range, i suppose?

So, to get a few things straight.

1) There is no DMA whatsoever with IDE on classic?
2) SCSI is still the "standard" when it somes to speed?
3) There is nothing "in-the-works" to "cure" No.1?

That's what i meant to find out.

So, i need to use an Acard bridge?
A normal UWSCSI->IDE adapter won't do it?

About the speed, at least the Acard ads say that the IDE drives takes advantage of the SCSI bus in terms of speed.
I knew about the DMA issue on classics. So, that's a backstep then, too?

Hmm, too bad

Maybe, i'll better get me a new and already silent UWSCSI HD and CDRom?

Any objections on that one?

Thank you

Hi Amigans,

i wanna migrate from SCSI (noisy, expensive) to IDE/ATA on my Amiga4000.

I have a Cyberstorm with UW-SCSI on-board and would appreciate any comment/advice on possible hardware solutions.

I already looked at the Acard bridge adapter, but it's not exactly fitting my needs, the description says it has to be plugged right into an IDE HD which means i can only use ONE HD on the SCSI chain (and it would prevent me using further methods on silenting the amchine, e.g. capsulating the drive).
It also sounds a bit silly (only one drive), given the price of that thing.

Next thing i looked at was this adapter, but i dunno if this would help in any way, it's just an adapter and that aforementioned bridge is kinda recomputing with an extra chip on-board, isn't it!?

I know that there is no DMA IDE solution on classics (yet?), but i could use the bandwith of the UWSCSI.

So, what would be your advice/tips/hints?

I don't want to plug it into the slow A4000 onbord IDE and can't use the IOBlix one for known reasons

Thanks in advance

Still some beta testing left to do ;)

Yep -- and icons left to paint!

Been at this for 5 weeks -- about 100 done -- about 900 to go!
