again me ;) also when probing the 25 pad (SCK) of SIO with the scope, there doesn't seem to be electrical activity on this node (it stays tied @ 5V all the time..) also I have given an erroneous measure in my previous mail: the frequency of the spi clock is 16 MHz and not 25.. Florentin

SPI detection/flashing support is on my list.
Is the SPI flash connected to the sio on the m57sli?
No idea.
So we should find out.
Ward - do you have a continuity tester? Could you see if the SPI flash chip is connected to the Super IO?
If I get a high-res photo of the Super IO and the flash chip area I can mark the pins that should be connected on both to get a yes/no indication.
I didn't think that's where the flash chip was actually connected.
AFAIK CK804/MCP55 don't have SPI support. That's why the SuperI/O adds it.
Intel ICH has SPI, but maybe different for NVIDIA chipsets.
The logic design controlled by the boot-from-PCI jumper on the m57sli is less obvious with external SPI, but it's still entirely possible. I hope it is this simple! :)
