Thanks Darrin.
I'm gonna put this forward too, so obvious it is stupid maybe? If the ROM OFF is set, then there is no way that I get to the goodies, says:
"ROM OFF: disable activation of FlashROM contents during booting. In case of problems when starting the computer with DENEB installed you can set this jumper to disable the FlashROM."
And this,
"During the first installation of DENEB in your system the RESCUE jumper must be set (got that part right). This allows accessing the (non erasable) installation software which has been stored in a specially protected area of the DENEB FlashROM."
Sooo, these are what you call "mutually exclusive" me thinks. FlashROM if off, who cares what RESCUE is set to, it's ignored. Verify my understanding?
So, I may need to get over this DMA buster thing after all...
Wonder if AmigaKit has one around?
