First of all, Thank you for your reply.
I've already read this manual before. But, although Table 35 (page 72) shows they are in the "Host Processors" range, Table 36 (page 73) doesn't include them. So, I can't figure out why the system hangs up. Is it a unrecoverable processor problem? That's why I'm searching for a complete POST codes table.
Does anyone know how to get information from Intel about undocumented POST codes like these I got (14, 15 and 17) for my DX58SO?
Thanks in advance!
