As have I. I found that the IOC firmware has undocumented 0dh and 0eh commands. Command 0x0d allows the main CPU to write to arbitrary IOC memory, and is probably for diagnostics, but is not allowed unless IOC RAM location 5af4h contains the value 24h, and I haven't figured out how that can be made to happen, since you can't use command 0x0d to set it if it isn't already set. I haven't yet figured out what command 0eh does. Best regards, Eric
Perhaps this document will be of use. I don't think I've passed it along. At one time I had a pretty good source for internal information. Friends who worked in the development teams...
