do a 'man hdparm' ; this will tell you about which command line
switches you can use in conjunction with hdparm - a tool to test
your hdds' speed and change various settings such as udma mode,
read-ahead, etc.

or, you can go here for a guide on the subject.

good luck.

I tried hdparm.
seems that my pci ide , or to be exact , my motherboard chipset is not supported in linux.
Somehow I need a patch or an upgrade to kernel.
Whatever that will work.
Since I don't know how to make use of these, i need help in instructions too.

You could try adding the settings you want to make in;

/etc/rc.d/rc.local

Just use a text editor such as vi or whatever, make sure you save it!

Hmm yes , but for dma hdparm says device not supported.

I am sure that my board supports dma and udma66

It works fine on xp.
My guess is my board is newer so, the chipset or pci controller is not being recognized in xp.

Are you logged in as root, in single user mode?

What are the exact parameters you are trying to use, post them in.

Are you using the correct parameter for your harddrive?

OK probably a stupid question, but have you got DMA enabled in your BIOS configuration?

I think you are right in saying you need a patch for your kernel or maybe even better to install the newest one. You maybe better off asking advice about installing a new kernel in a different forum than this one, I don't know. Somebody more knowledgable on this will have to help you out.

Good Luck, sorry I couldn't be of more help
