A few questions from a new user of this utility (previously I relied on motherboard BIOS for this).
1. Is it me or does SETMUL L2D not work with P54C CPUs? It seems to have no effect on performance that I can discern and CACHECHK can still find 256K of cache when I try.
2. My P133 after using SETMUL L1D scores around what Speedsys says a DX2-66 should score (~25) and when I set it to 50MHz FSB I get around what a DX2-50 would score (~20). However DOOM runs painfully slow in full screen, probably the way it would run on a 386DX (<10fps) and certainly much slower than I remember it running on my DX33. For reference, I ran Phil's Doom benchmark for faster machines (fullscreen and high details), and got 2134 gametics and 1159 realtics with Cache On vs 2134 gametics and 6143 realtics with L1D. Is this because the L1D option disables L1 and L2 together? Should I have used L1DX instead, and is this supported on a P133?
3. As an extension of the above, seeing as the Speedsys results aren't really representative of my system's performance for whatever reason, which benchmark is a good gauge of where my system is after playing with SETMUL options?
4. Will using my K5 PR166 give me more control over the L1/L2 caches with SETMUL? There are a lot of references to SETMUL and K6 but not many people seem to have tried it with K5?
