BTW, I am getting lots of error messages and messages saying some processes failed while booting in Debian:

While calculating module dependencies it says "hda: dma_intr: status=0x51 (DriveReady SeekComplete Error)" and {addrmarknotfound}
and similar messages many times.

And somewhere while booting it says "Missing Kernel or usermode driver...." I couldnt write all the messages it gives while booting but I can see that not everyting is working right. Does this help one of you experts to diagnose the problem?
