Xfree86 4.2 screen modes

Folks, I've noticed the xconfig file mode section in 4.2 is different from the previous versions in that besides the row x col entries there is a list of decimal numbers which appear to be sync or something. I've looked through the XFree.org web pages for 4.2 and I cannot find any documentation for the syntax and definition of the mode lines. Anybody know how to interpret these and where I can find some useful documentation? Thanks! Babu __________________________________________________ Do You Yahoo!?
