Hi, I was reading this thread as the problem I'm having seems quite similar, and with version 7.2, although I had the same behavior with 6.3 as well. The only variation on the dialog below is I do not have any CDROM or other device attached. My configuration is: primary IDE: 10GB Seagate seconardy IDE: 80GB Maxtor My dmesg is giving me ad0: 9541MB <Seagate ST310212A 3.39> at ata0-master UDMA66 ad2: DMA limited to UDMA33, controller found non-ATA66 cable ad2: 76345MB <MAXTOR 6L080L4 A93.0500> at ata1-master UDMA33ad0: 9541MB <Seagate ST310212A 3.39> at ata0-master UDMA66 ad2: DMA limited to UDMA33, controller found non-ATA66 cable ad2: 76345MB <MAXTOR 6L080L4 A93.0500> at ata1-master UDMA33 Any ideas?

However the ata driver sometimes warns: ``DMA limited to UDMA33, non-ATA66 cable or device''. This means that the ata driver has detected that the required 80 conductor cable is not present or could not be detected properly, or that one of the devices on the channel only accepts up to UDMA2/ATA33. ========================== You've got your 40GB Maxtor (you've installed FreeBSD on it), an ATA100 device, connected with your CDROM, an ATA33 device. The result is: your boot drive is running at UDMA33 instead of UDMA100. This is not going to work real well, as you can see. Do you really need that 40GB Maxtor? If you do, you're going to have to try adding an ATA controller card into one of your PCI slots and use that to connect your hard drives to. Try removing the 40GB Maxtor and reinstalling FreeBSD on the other two drives. I think that will clear up some problems for you. Don
