Question ATA 100 HDD reports no DMA

There actually are several questions related to my hard drive.
1. during the boot time BIOS says my HDD is "LBA ATA100 120Gb". Do I have to pass any parameters to kernel in order to use that "100". AFAIK, the default is 33. I can increase this to 66 by adding something like "idebus=66" to the "kernel" string in GRUB's menu. I can well be missing [mixing up] something.
2. dmesg says no DMA found. hdparm says dma is not enabled (and I can't enable it). reiserfsck warns about the same thing. All this makes me think that the motherboard does not contain a particular piece of hardware (what does "dma" look like, anyway? - is it "sotf" or "hard"?)
