Hi all, I've been trying to find out this answer myself but I am not having any luck with the Dell documentation. I have a new Poweredge 350 which seems to be working fine, apart from this oddity: atapci0: <Intel PIIX4 ATA33 controller> port 0xffa0-0xffaf at device 7.1 on pci0 [...] ad0: 38146MB <IC35L040AVER07-0> [77504/16/63] at ata0-master UDMA33 FreeBSD is reporting the controller as ATA33 capable only. The ata(4) man page says this is its maximum speed, and a web search for 'Intel PIIX4' shows this appears to be correct. What I am _hoping_ is happening is that the chipset in this server is backward compatible with the PIIX4, and FreeBSD is not properly detecting the native chipset. I find it hard to believe that a brand new server shipped with a 7200RPM ATA100 drive would have a controller limited to ATA33 only? It may sound like I'm niggling but as I often do HD image backups it is relevant; even the older 5400RPM ATA66 drives can saturate the ATA33 controller on my other server (31-32Mbytes/sec). Thanks in advance for any help...
