So far I tested about 3 three different 440BX based boards with a 133MHz Pentium-II, and they all disable the L2 at that speed.
About three other people reported the same with their 440BX boards.
Only swaaye and elianda seemingly have the L2 working on the 440LX.
L2 does not matter much in the DOS game benchmarks I did, maybe the L1 size on these P-II's is already sufficient? Also the L2 on the P-II is half speed and would be running at just 66MHz. Still the disabled L2 is annoying me somehow. Maybe a slot-1 Pin-mod would make a difference....
Setting a P2 to 133 MHz is not really special though.
Swaaye did this very nicely for his architecture comparison at 133 MHz with different CPU cores.
But that is not that long ago. About 4 years ago P-II's were considered poor DOS retro material here, But now it is well known that some can run at 2x and they are used more often.
