I prefer GNOME.

Good news. The Linux kernel performance issue with SiI 3112 SATA controllers is going to be fixed! Here is a message from the kernel maling list by Andre Hedrick who is working with Silicon Image to get the fix prepared and put into the kernel: Quote: I have a scheduled fix prepared for release and review by SiI monday morning (October 6th) 9AM Pacific time. Once it is cleared by SiI, it will be released out to the masses. I can only chortle over the issue of how attempts to replace me, and me trying to escape the indenture servant slave of maintainership yet still bound after nearly 6 years. Will attempt to address the mod15b phy issues Cheers, Andre Hedrick LAD Storage Consulting Group

hey, thanks for the help. I'm am using an nForce2 board, in fact. the Abit NF7-S. its an awesome board... but I've already given up and pulled out my Serial to IDE converter. I might be sacrificing a bit of potential performance but i don't mind at this point. at least now I can have my SATA controller disabled which speeds up my boot time quite a bit because before the BIOS and the kernel had to both query the SATA controller for drives which takes several seconds for each of the 2 channels...

i tried this and the second number i got was: 64 MB in 48.56 seconds = 1.32 MB/sec pretty impressive, eh?.... i'm going to try a couple more kernels (maybe see if 2.6pre will work) and then i'll just have to get rid of the converter and go back to IDE. however, i'll have to reinstall RH at that point, i'm sure, although i think windows will be OK.

oh, and, can anybody tell me how i might go about figuring out exactly what kind of HD drive performance i'm getting (MB/sec)? i've seen people reporting how many Megs/sec they're getting. how do they find this? thanks.

Quote: Try the hdparm command mentioned earlier in the thread, that should help a bit. What's happening is that it might be detecting the controller but it's not setting the correct DMA mode resulting in the effect you describe. If you don't want to have to enter the command every time you log in open up the file /etc/rc.d/rc.local (I think that's where it is, my memory of Red Hat is fading fast) and add it to the end. thanks for the input by i've already tried % hdparm -X66 -d1 /dev/hde and it completely disabled my HD. my home directory showed up empty and i couldn't bring up anything that wasn't already in RAM. so, i think i'll have to scratch that idea. i didn't get the feeling that it was very healthy for my HD to give it that command... by the way, I'm using an IBM/Hitachi Deskstar ATA100 120GB hard drive with a serial to ATA convertor. i may just have to get rid of the converter and go back to IDE but i get better performance under WinXP with the converter. thats why i was using it...

I keep hearing this 'kernel 2.4.x doesn't support SATA' stuff everywhere but I'm afraid that I was able to install Red Hat 9 (2.4.20-8 ) using my mobo's Silicon Image iI 3112 SATA controller just fine. Red Hat found my hard drive immediately and the only problem I'm having is that it seems to be running slowly. When I'm moving/copying large files my system becomes completely usesless (choppy mouse movements, apps won't launch) and on top of that data seems to be being read/written slower than it should be. Does anybody know how I can get SATA to work as well and as fast as IDE? I'm using an IDE to SATA converter on my hard drive. Is this the problem (I'm pretty sure its not, but...)
