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...
