Don't know about the format, but if you look thru old ITJ articles[^1], it seems like the "direct access" interface for reading out different memories exists on older Pentium parts too. Presumably, if it were possible to dump over JTAG, it would be at least a little bit similar to what Peter/Mark have already looked at on newer parts.
