This seems like a very inefficient design to me. :-) This is what Intel planned originally. However they failed to account for the Independant Motherboard Manufacturer. These days a lot of the motherboards will take a 486SX or DX interchangeably, with a simple jumper setting, in the same socket. They often also have the extra socket for the overdive chip (modified 486 DX2 or the mysterious chip- to-come). -- ------------------------------------------------------------------------------- Iskandar Taib | The only thing worse than Peach ala Internet: NTAIB@SILVER.UCS.INDIANA.EDU | Frog is Frog ala Peach Bitnet: NTAIB@IUBACS !
