@PQuasar
Not really in the Amiga-design, but in the Mediator, which just couldn`t handle
such an amount of data (*), the Mediator isn`t a Z3-DMA card itself and has no ROM
to allow autobooting from such a controller.


Nuff said ;)



*Yes I know Elbox's babble bout benchmarks, but these are allway between a PCI card
and a nonexistan PCI-master(shark). Transferrate PCI to Zorro/Amiga are dead slow in
comparison.

1. Make an announcment.
2. Wait a while.
3. Check if it can actually be done.
4. Wait for someone else to do it.
5. Start working on it while giving out hillarious progress-reports.
6. Deny that you have ever announced it
7. Blame someone else

@Grumb

Z3-DMA just isn't possible with the programmable chips used on the Mediator.

Using different chips would result in a completly different design ;)
(and would cost a fortune with such few units build)
