Hi guys, Does anyone know when Linux will support ATA100 ? I would like to get the maximum out of my hardware. If it's allready supported, can somebody point my to the right links ?

Hi guys,
Does anyone know when Linux will support ATA100 ?
I would like to get the maximum out of my hardware.
If it's allready supported, can somebody point my to the right links ?
Tnx in advance,
ATA100 PCI cards have been supported sinve the 22 kernel and the 2.4 kernel (including that in 7.1) supports the onboard controllers. Charles (-:Forever never goes beyond tomorrow.

Hi Charles, Your response prompts me to ask whether you know what sort of transfer rate I should see. I have a correctly cabled IBM Deskstar ATA 100 (DTLA 307030) running under 7.0 and my home-compiled 2.4 kernel on an 815e mobo (Asus cusl2). So far as I can tell I have set everything correctly in the kernel, including dma. Hdparm reports UDMA mode 5 in use. When I run hdparm -tT, however, I see : /dev/hda: Timing buffer-cache reads: 128 MB in 1.03 seconds =124.27 MB/sec Timing buffered disk reads: 64 MB in 4.13 seconds = 15.50 MB/sec I know that hdparm is a crude tool for benchmarking a hard drive, and that one never gets the "full" transfer rate in the real world, but 15.50 MB/sec, seems very slow. I would be grateful for any observations / advice. Regards, Geoff _________________________________________________________ Do You Yahoo!? Get your free @yahoo.com address at http://mail.yahoo.com
Enable DMA by default (Also a kernel option, and I think this can be done by hdparm also) Using this I get 25MB/sec plus with my UDMA-66 drive.

Hi Muzh, Thanks for the response. I did in fact have dma set in my kernel, but it was helpful to see your 25MB/sec figure for purposes of ccomparison. This led me to do some google searching and I found a long discssion between linus and other kernel gurus in the past couple of months concerning problems with udma 3/4/5 and certain drives - including my DTLA. I did not understand everything I read, but I think that the bottom line is that I am going to have await some code changes before I get full speed.

This is slightly OT here, but is there a similar tool that can be used with RAID arrays (/dev/rd/c0d0px)? Ken -- "We can build a better product than Linux..." -- Microsoft VP Jim Allchin
From kernel 2.3.xx (In practice 2.4.x) Just compile it in or as a module -- there is a fair choice of drivers to choose from --
