Date: Mon, 4 Dec 2000 00:44:59 +0000 Hi, I'm experiencing the same problem in getting UDMA66 out of FreeBSD. dmesg snippet follows: ... atapci0: port 0xd000-0xd00f at device 7.1 on pci0 ata0: at 0x1f0 irq 14 on atapci0 ata1: at 0x170 irq 15 on atapci0 ... ad0: 9773MB [19857/16/63] at ata0-master UDMA66 ad1: 4110MB [14848/9/63] at ata0-slave UDMA33 acd0: CD-RW at ata1-master using WDMA2 acd1: DVD-ROM at ata1-slave using UDMA33 I believe I've got round the problem by editing ata-dma.c and commenting out the code that sets udmamode back to 2 (which the above dmesg shows). Anyone knowing a good I/O benchmark to confirm this please let me know. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
