winteum Posted October 29, 2006 Share Posted October 29, 2006 I don't know why but today i realize that my osx86 are slow. Ran Xbench and got this: Results 28.05 System Info Xbench Version 1.3 System Version 10.4.8 (8L2127) Physical RAM 1024 MB Model ADP2,1 Drive Type SAMSUNG SP0822N CPU Test 43.15 GCD Loop 76.79 4.05 Mops/sec Floating Point Basic 67.94 1.61 Gflop/sec vecLib FFT 22.20 732.40 Mflop/sec Floating Point Library 50.20 8.74 Mops/sec Thread Test 53.16 Computation 37.34 756.41 Kops/sec, 4 threads Lock Contention 92.23 3.97 Mlocks/sec, 4 threads Memory Test 68.58 System 52.97 Allocate 79.27 291.09 Kalloc/sec Fill 43.71 2125.22 MB/sec Copy 47.30 977.04 MB/sec Stream 97.21 Copy 103.44 2136.61 MB/sec Scale 105.05 2170.37 MB/sec Add 91.27 1944.26 MB/sec Triad 90.87 1943.94 MB/sec User Interface Test 58.62 Elements 58.62 269.05 refresh/sec Disk Test 9.56 Sequential 7.26 Uncached Write 5.82 3.57 MB/sec [4K blocks] Uncached Write 6.34 3.59 MB/sec [256K blocks] Uncached Read 11.44 3.35 MB/sec [4K blocks] Uncached Read 7.47 3.75 MB/sec [256K blocks] Random 13.97 Uncached Write 7.73 0.82 MB/sec [4K blocks] Uncached Write 11.40 3.65 MB/sec [256K blocks] Uncached Read 66.94 0.47 MB/sec [4K blocks] Uncached Read 18.42 3.42 MB/sec [256K blocks] I don't understand, before my results reaches 57. You see that disk access are too slow and dropping my overall result. What do you guess?

I'm trying to recover to nforce and can't get it. How can I to substitute AppleGenericATA with nforce?

winteum Posted October 31, 2006 Author Share Posted October 31, 2006 If I remove the AppleGenericATA can't boot again. --> still waiting device How to configure to recognize the onboardATA as default PATA?
