Actually, the old code was wrong. The 1742 only uses the registers from 0xZc00-0xZcff. Looking at the register definitions in the driver file itself will verify this for you if you have any doubts. After all, how do you think it would find the card at all let alone probe any devices on the bus if the base addresses were wrong? >NEWKERNEL will hang the system without a panic or a message in >/var/log/message.

If you want to hang the system, it is quite repeatable >with `iozone 32' in /usr/tmp. Sounds like an interrupt problem. I guess I'll have to install the 1742 that's on my shelf and see if I can reproduce this. Can you tell me what other devices are in your system? >One other point, to get NEWKERNEL to config and compile, I had to >edit sys/i386/conf/files.i386 and comment out the i386/isa/aha1742.c >line. Otherwise, you do not pickup the file aha1742.c. Whoops. Looks like I missed that change in my commit. I'll fix that later tonight. >-- >Steven G.
