C'mon, Sean, you're more imaginative than that! You just leave a hole where you move the FP regs out (leave a dummy of the structure there) and adjust sizes where you put them in. Check it carefully, and the offsets to the stuff used by drivers can remain the same. (I'm *not* the one doing the change. This is just a general observation based on what needs to happen. The hard part is NOT the principle of keeping essential parts of the u-area compatible; it's the many practical matters involved in ensuring that you don't screw up something else in the process.) -- Dick Dunn rcd@ico.isc.com -or- ico!rcd Boulder, CO (303)449-2870 ...But is it art?
