I have a Gigabyte 8KNXP which uses the Intel 875P chipset (almost the same thing) and a pair of Seagate ST3120026AS (120 GB Barracuda 7200.7) disks. They seem to work fine with FreeBSD 4.9-Release in either native or legacy mode even though 4.9-Release understands the ICH5 SATA controller only as yet another model of ICHx ATA controller. The driver thinks the disks are on an old 40 conductor IDE cable and tries to do dma at ATA33 speed, but the controller ignores the driver and runs at SATA150 rates. I used to operate the ICH5 SATA controller in native mode but had to switch to legacy mode because the AWARD BIOS won't boot off the controller in native mode. Legacy mode is less than ideal because the driver can't operate both drives at once. FreeBSD-current probably understands the SATA controller better than 4.9. I used to use 5.1-Release but had to give it up because it was just too flaky. (The rest of 5.1 was flaky. The 5.1 ATA driver seemed to work ok.) I have not attempted to upgrade to current because the traffic in current@freebsd.org suggests that it works correctly only on alternate weekdays. I have made no real attempt to stress the disk system. It seems to work. I have used it to install FreeBSD several times and caused hours of continuous disk activity building ports and running miscellaneous programs. I have noticed no hiccups. Dan Strick strick@covad.net
