It is a while. The problem is restricted to my 150x reader only. Now, the problem is the USB speed of N1200. I've gave up to use the N1200 to read the SD directly. I use a Window machine to read SD and save to N1200 instead.
I am rather interested to use the USB port to connect a web cam, where speed is not demanding.

The 10pin flat cable is for some old motherboards that don't have DB-9 male connector on board. Besides, N1200 board comes with 8 pin header only, that's why I said 9-10 not connected.
If you custom-made a cable, only 3 wires are required. Pin 2, 3 and 5. Since the null cable is for Rx/Tx crossing, so if you still find the console does not display, just swap pin 2 and pin 3 and try again.

It is located at J1. Same pin assignment as a DB-9. Since it is 8 pin header, pin 9 is not used.
You can buy a 10pin flat-cable type DB-9 cable, with 1-2 aligned, 9-10 not connected, in addition to a null modem cable, you can see the message coming out at 115200 baud rate.
Enjoy.

Planned to use the N1200 to send Magic Packet to wake up a computer on its LAN port. Get my friend to prepare a full boom "busybox". It comes along with "ether-wake" utility and more. I did try ether-wake only, successfully wake up a standby XP. let me know if you have tested any other additional utilities. www.mediafire.com/?dgdecmbzbtrEnjoy.

Have you considered to install application (DVR ?) + USB driver to the existing OS ? Should be easier. I think if you are not happy what existing OS offers, for example, the TCP/IP stack cannot help me to fragment a jumbo frame into mutliple 1.4KB packets automatically, you may need to reinstall a new kernel.

Does anybody know what webcam server is using at N3200 ? I would like to add this feature to my N1200.

The PCI slot is intended for Wi-Fi card expansion. Thecus has prepared some drivers for this expansion, definitely not including any memory card. For PC desktop market, some manufacturers built PCI memory card, intended for hard disk replacement, I would say a hard disk cache.
I recall that the N1200 PCI is 66MHz, 32 bit wide. Performance wise, it is not matching with 64 bit wide 266MHz DDR1 memory. Most important, no manufacturer is intereted to build mini-PCI memory card.
I have two NAS at home, N1200 always runs BT, another NAS (old PC)is quite idle. I am thinking to transfer the on-going BT task to the old NAS at evening time (when I am at home). Then N1200 will have more Bwidth to do other things.
Just an idea to maximize the N1200 utilization under limited resource.

The DDR1 DRAM chips are soldered on the board. No DRAM expansion card slot is provided.

My N1200's fan had died several days ago. There is loop beep alert. When I opened the case, I found the CPU heatsink has fallen off. Since I have overclocked the CPU. thecususergroup.proboards106.com/index.cgi?board=n1200modifications&action=display&thread=1186119015 Improving the CPU heat dissipation is one of my task. The original CPU heatsink is several mm away from the case, and plastic adhesive tape is used to adhere the heatsink to the CPU. I replaced it with higher heatsink. The black one is the original. Then clean up the CPU surface. The adhesive stuff is quite sticky. Then clean up the new heatsink. R hand side is the finished one. Paste a good thermal conductive grease on the CPU and heatsink. Press the heatsink firmly on the CPU. Paste the grease on the heatsink top. Fix the heatsink with epoxy resin (A+B gum) on 4 sides between the heatsink and CPU. The transparent stuff is the epoxy. Note the foreground header is the serial port header. I can feel the heat at the case now !! I may plan to overclock the CPU to 533MHz later. If you plan to do that, don't peel off the heatsink directly. Heating it up is suggested.

I have the same 320GB HD as yours. It died after 9 days inside my N1200. Right before it dies, I plugged a USB HD to the N1200, and tried the "USBCOPY" function. Maybe the global warming plus hot weather of Hong Kong, anyway I gave up to put a 3.5" inside N1200. Besides, a HK computer magazine ranked N1200 is the worst NAS with high HD surface temp at a publication. After the replacement, I put this 320GB at the eSATA port and spin it down for 20min idle time. Only at eSATA, SATA port cannot be spinned down. A 2.5" 40GB HD is inside my N1200 now. Works OK, but the fan will get noisy for every 4~5 days.

Freescale PowerQuiCC family suffice "E" means encryption engine. Frankly, with or w/o "E" contains the engine. Owing to this engine still has strict export control to places such as N Korea and China. The documentation on the web is good enough. What the key factor is the u-boot operation. If the operation is not correct, you may need to reflash the board with the JTAG port. It will be more complicated, and I don't know where is the JTAG port yet

I tell the concept 1st. Freescale 834x CPU can operate the CPU core from 266 to 667MHz. There are multiple PLL (simply speaking clock multiplier) inside it. In order to avoid the modification affecting the serial port and DDR clock rate, only the CPU PLL would be modified. The internal bus clock (CSB clock) remains 266MHz, then you can modify it the CPU multiplication factor from x1 to x1.5. The CPU fetchs a HRCW (config stuff) from the 1st 32 bytes of the flash during reset. The factor is at the HRCW. The modification can be done at u-boot. Modify the CPU multiplication factor only. Copy the 1st sector ( I guess 256B) to the DDR, modify it and write it back to the flash.
