[-- cut --] Actually, this has been hashed over several times. I'm using several Athlon boxes with the same chipset (and some KX133) with no problems. Usually those errors (according to Soren) are from interference on the ata-66 cable, or improperly spec'd ata-66 cables. Make sure the cable doesn't exceed 18" and that's it a verified ata-66 compliant cable. Make sure it's tied up and not hanging near any of the voltage regulars or anything else that generates RFI. It should also be noted that some "ATA-66" hdd's are not 100% ATA-66 compliant. WDC suffers from this, as does some Quantum drives (which I use almost exclusively). I've not heard anything bad about IBM (which I've just started buying into). Maxtor suffers from this problem terribly, not to mention problems with DMA transfers even @ ATA-33 (what do you expect for cheap gear? :)) Hope that helps some, here's my dmesg from one of my boxes with relevant info (this one happens to be using WDC drives on a ASUS K7M motherboard.
