AMD 8131 / 8111 chipset with VERY SLOW PATA IDE

[rafafre]

I was finally abble to install OSX Leopard into a very strange and problematic setup. I`ve tried almost every distro out there, and only Kalyway with speedstepkernel worked out. It`s a Tyan K8SR motherboard with two Dual-Core processors, opteron 270. All cores are working, very fast processing. Also Network works great on both onboard ports. USB also works. Video is simple VESA, but works. Now, the problem is Hard Drive read and write speed. It`s really really really SLOW!

 

I`ve used Kalyway 10.5.2, and installed both AppleVIAATA.kext and AppleGenericPCATA.kext. In the system profiler, the VIA driver isn`t load at all. It`s working (kind of) now with the generic driver only. Well, to have an idea, here is what XBench says:

 

Sequential 4.50

Uncached Write 3.88 2.38 MB/sec [4K blocks]

Uncached Write 4.08 2.31 MB/sec [256K blocks]

Uncached Read 6.90 2.02 MB/sec [4K blocks]

Uncached Read 4.14 2.08 MB/sec [256K blocks]

Random 10.56

Uncached Write 7.53 0.80 MB/sec [4K blocks]

Uncached Write 7.12 2.28 MB/sec [256K blocks]

Uncached Read 66.24 0.47 MB/sec [4K blocks]

Uncached Read 11.06 2.05 MB/sec [256K blocks]

 

So, that sucks, no?

 

Now, I`ve looked for info on this subject extensively, and I can`t find any info on how to resolve it with my chipset. There was a talking about a modified applePCATAgeneric kext by Medevil, but I can`t find it anywhere in the net. Does anyone have this driver so I could try it? Or maybe you should point me in the right direction for putting this PATA chipset to work, with another drive or mod, I don`t know.

 

Thanks for any replies!
