spfd do you ever read the manual? i have an asus mobo. what i'm guessing in your case, after reading my mobo manual
is that the jumpers on the mobo is for setting the maximum speeds of certain buses for the system. you would still have to set the configurations in the BIOS unless it is automatic.
for example on my asus a7n8x dlx mobo there are jumper settings to use either a 200mhz or 266/333/400mhz system bus support using the typical 1+2 or 2+3 jumpers settings. read the documentation on the asus website should tell you what those jumpers are spfd
