Yep, that's a jumper all right. I wonder what it does.

Good photos! I put some labels on interesting pads on the soic detail photo; available at: http://stuge.se/m57sli_soic_detail_labels.jpg We want to investigate two things: 1. Dual flash chip mod on this board 2. What is driving the flash chip - super io or southbridge? For 2 I need to put some labels on a super io photo, so let's start with 1. For the first iteration, please check: * which signals are connected straight across between U5 and U9. (I suspect SI, SCLK, HOLD#, VCC, GND, WP# and maybe also SO are all connected across.) * what Q4-1, Q5-1, R99-1 and R102-2 connects to on U5, if anything. //Peter -- linuxbios mailing list linuxbios@linuxbios.org http://www.linuxbios.org/mailman/listinfo/linuxbios
