IDE - usb through a Spider - a good alternative to powerflyer?

[tjaoz]

@Boot_WB

Powerflyer transfers are higher as the data does not need to be processed through the stack eating the CPU power.


@Piru

> Well, I'd recommend you don't trust Elbox marketing talk anymore you trust anyone elses.

You really do not know that Mediator/Amithlon drivers for the Spider card are USB 2.0 (EHCI) and USB 1.1 (OHCI)?

At least you, a person who is involved in the promotion of pirating the Spider drivers, should know if Spider drivers are 2.0 or 1.1? :lol:

So you know wrong.

Spider is High-Speed USB 2.0 card. Spider card includes the USB 2.0 and USB 1.1 controllers. With the Spider card Elbox supplies drivers for both controllers: EHCI (USB 2.0) and OHCI (USB 1.1).

The speed of the USB 2.0 devices connected to the Spider card is limited by the turbo card connected to the Amiga. Amiga turbo cards have not enough power to process USB data faster. The speed of the USB 2.0 devices connected to the Spider on the system running Poseidon with Spider drivers under Amithlon is exactly the same like with the Windows USB 2.0 drivers.

The same applies e.g. for Bugatti (www.bugatti-cars.de). They are advertising Bugatti Veyron 16.4 running at velocity 400km/h, but failing to mention it's only in optimum cases. :crazy:

Do you think Bugatti should mention in their site that you will not be able to drive their Bugatti Veyron at 400km/h due to the road quality or speed limitation in your country? :lol:

@Piru

Yes, you do.

Even in this thread you link to your website which encourages pirating Spider drivers, where there are notes how to crack Spider drivers. Moreover, you also offer software tools needed for pirating these drivers.

> But is the Bugatti Veyron limited to 20km/h?

Sure, it is. In residential areas. :lol:

@ChaosLord

Busspeedtest to the graphic card in Mediator measures the maximum speed at which the turbo card can read the $200000 -> $9FFFFF area. Some A1200 turbo cards do at 6MB/s, others at 8-9MB/s, still others at 12-14MB/s, and some at 18MB/s. It all depends on the hardware design of the turbo card.

If busspeedtest in your A1200/060 reads 9MB/s, it means that your turbo card cannot access this area faster. It is the hardware limitation of your turbo card -- not limitation of Mediator.

Maybe you should submit complaints with the designer/producer of your turbo card, if they "annoyingly and intentionally do not mention these facts on their website"? :lol:

In the text on your website, someone (you?) writes what should be changed in the Elbox driver code to use this driver without Elbox restrictions. (These restrictions allow their usb driver working ONLY with the Spider card hardware.)

Next he (you?) describes what problem he (you?) found in the Elbox code during cracking it.

At the end, he (you?) writes: 'This archive was all made by me and contains code written by me. Nothing from Elbox.'

In the same way you can describe how to crack any other commercial software in order to break its restrictions.

Do you remember the email on the Mediator list with info how to break the Poseidon registration restrictions? This mail was treated as abusive despite that it only had info on which byte to change in the Poseidon code to remove restrictions on the unregistered version. You think such instructions are legal? :shocked:

Your website holds not only instructions what should be  changied in the code of the Elbox driver, but you also include a tool for decrypting the code of this driver, which is necessary for cracking it.

Sorry, it is not my busines...
Still, I wonder why moderators of Amiga.org allow you to post links to such texts here.

Why not?

The $200000 - $9FFFFF area is not used by A1200 motherboard at all. So what speed turbo card accesses this area depends on the hardware design of the turbo card only.

All accesses from the turbo card to this area are directed only to the external hardware (like Zorro II, Zorro IV or Mediators) connected to the CPU slot. If external hardware acknowledges cycles immediately (the case of the Mediator WAIT jumper opened), there is obvious that the speed at which this hardware is accessed is limited by the turbo card interface hardware only.  :-D

You are wrong.

It is funny to hear about ethics from someone from the US under Mr. Bush.  :lol:

Yes, I understand. You are 'Piru'. 'Qwe' is not you.
So, who is 'Qwe"? Your keyboard? :lol:

So if cracking instructions for Poseidon stack would be given in the form of speculations, would it be ok? :-?

Are you really ignorant or do you only pretend to be so? :-o

:roflmao:
What requirements for accessing the $200000 - $9FFFFF area?
Could you be more specific?

What for?

I know that Mr E3B has been trying to repair the Prometheus design for many months, as the original Prometheus does not have working PCI-to-PCI, and does not have DMA to Amiga motherboard at all.

Sorry, but I do not intend to help him. He should learn himself.  :-P

What was pronounced on several news pages? That the original Prometheus does not have working PCI-to-PCI, and does not have DMA to Amiga motherboard at all?

When I wrote about these facts on Amiga.org there were always some "eyewitnesses" saying that PCI-to-PCI works well in their Prometheus boards. :lol:

I suggest you read my post again, and this time try to read it with understanding. I clearly wrote about the 'original' Prometheus, not about your experimental toy. Whether it works or not. :-D

Many designs have been completed for Amiga, which others believed to be impossible.
 
You'd better wrote that making DMA to Amiga motherboard is too complicated for you. It's obviously not as easy as fix the PCI-to-PCI DMA in Prometheus. :lol:

You can send your Prometheus board for reflashing since January 2002. :roflmao:

Forgive me, but I couldn't resist.  :roll:
