- Uh, Intel's first overdrive chips, which were made available earlier
- this year, were expressly designed for the 486SX. I'm not even sure
- that Intel has yet released overdrive chips designed for DX machines.
- (though if they haven't they shortly will for 25 Mhz and 33 Mhz DX
- machines). As of the last time, I looked, the overdrive chips available
- were for the OverDrive sockets of 486SX 16-, 20-, and 25-MHz systems
- (or, as an alternate, OverDrive replacement chips for systems with no
- extra sockets).
