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

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).

but if the intended application cannot benefit from that speed why claim it? you can't tell me it was designed for use between two pci slots. this is just a misleading statement nothing more.

I suppose if they ever release the SharkPPC :crazy: ...

But your information is outdated, as PCI-PCI DMA is running for months now on my Prometheus...

Out of curiousity, is there any timeframe for when ordinary users will be able to send their boards in for reflashing?

About direct PCI-to-Zorro III DMA conversion... well. I know it is not worth the time to explain to you, but if you were familiar with Buster design, you should know that it is not possible due to timeout constraints on both the PCI bus and the Buster side.

Does this mean that PCI busmaster devices cannot access motherboard resources?

I don't know much about PCI and Zorro III timing so feel free to dismiss this outright, but couldn't Zorro III DMA be implemented with a series of individual PCI accesses since PCI is much faster than Z3. It seems a single PCI read or write operating takes around 5 cycles or so (or can it be longer depending on the device?). Can the buster chip not wait this long for each data transfer?

We are running tests now with some external testers, and are evaluating the handling of the boards (shipment etc).

Please give us some time... it's far better to have it tested into the deep than giving away a fix which does not keep it promises (like the last reflash from the original designer :-(

I understand your desire to be absolutely sure given the costs involved with shipping boards all over the place. I also understand your reluctance to give a date since one problem could potentially push back the date significantly. I was just wondering if you could give some kind of educated guess. If you don't want to, I understand.
