You're saying the interrupts are correctly registered with the | devices (you get correct probe information), but the interrupts are | getting lost? Yes this is appears to be my problem. The probe finds the card, attaches the driver (ed). When I do an ifconfig I see the ether address but get a device timeout during pine. Looking on various web pages from TI in which they have an explanation of different interrupt methods. They talk about a bit that needs to be twitled in order to enable ISA mode interrupts to happen. So it is my best guess that interrupts are not happening since I had the same problem when I had and interrupts problem on my laptop with TI1130. I guess my question is, that when booting -v with a 6832 what does the probe return for the port of the 6832? On my card it returned 0. Then when it set the emulation to work at port 0, it didn't work. My setup is a bit odd. I have a 6832 eval card that goes into a PCI slot. A cable goes from this card to an ISA card to trigger ISA interrupts. Kind-of neat. Unfortunately I didn't get any programming doc's with this card so I need to ask for them. I have a belief that some laptop BIOS's have the code to set this stuff up so old drivers work with the new chip. Since, I'm just using a standard old PC my BIOS doesn't touch it. Hopefully I get a better kit from TI with better doc. Doug A.
