Well - after all you are asking for a documentation for a connector, which doesn't exist - there are just holes. I don't know about JP1 and JP3, but I would assume that one of them is a JTAG header, which, under normal conditions, is for production only. The boards are a mix of embedded, vs. normal PC boards. In the real embedded market you even can have the requirement for a schematic. I personally consider the board more normal PC boards than embedded ones and if you by a motherboard from a random vendor you never get a description about unpopulated headers as well. I think Søren is playing nice compared to them in that he answered a lot of questions for purposes that his boards are not designed for. There are more questions like this, which may or may not be insteresting. For example I also could ask: If I unsolder the CF header, what kind of chips can I solder on the fields hidden by the CF header? At least on the 45xx there are solder fields for chips under the header. You may say that this includes unsoldering components, but the thread started asking about headers that don't exist. It is true that other vendors are more informative, but it is also true that there are many vendors, which are less informative. I've made some expirience with chinese products and getting an answer about anything beyound pricing is impossible. And the board design made it impossible to ever put the board into a case without doing ugly tricks, but this is another story. > > How hard can it be to type a few lines about pin layout in a text editor? > > Bill asks a very good question. Rather strange that things are this way. Yes - having a manual for this board would be nice, but I don't expect that there is anything new in it. It will not tell about unpopulated headers - the 4501/4801 manual don't do it either. It mighr tell about the requirement for a 12V supply to use the internal header for supplying an SATA disk, but anyway the header isn't populated, so this feature doesn't officially exist anyway. -- B.Walter http://www.bwct.de http://www.fizon.de [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] _______________________________________________ Soekris-tech mailing list [email protected] http://lists.soekris.com/mailman/listinfo/soekris-tech
