Message-ID: <20020306223633.D485-100000@s096-n062.tele2.cz> MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-hardware@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org Hello, I've 2 IDE controllers in my computer (1 on the mainboard and 1 added PCI card). Both are ATA-100. FreeBSD finds them OK and all connected devices work. On the second controller I have 1 HDD (1st IDE channel) and ATAPI ZIP drive (2nd IDE channel) and none of them works with DMA. Even when I set dma with sysctl, it falls back to PIO mode. I am not sure about the ZIP drive, but I am sure the HDD supports UDMA (it's WD Caviar 15GB). The HDD is quite fast even when in PIO mode (about 3 MB/s), but the ZIP drive is extremely slow (about 50KB/s), which is annoying. In M$ Windows it works normally (at least 10x faster). Maybe the kernel sets bad PIO mode for the ZIP drive, but I don't know how to change it ? This is dmesg report about ata devices: atapci0: port 0xb000-0xb00f,0xac00-0xac03,0xa800-0xa807,0xa400-0xa403,0xa000-0xa007 irq 11 at device 8.0 on pci0 ata2: at 0xa000 on atapci0 ata3: at 0xa800 on atapci0 atapci1: port 0xbc00-0xbc0f at device 17.1 on pci0 ata0: at 0x1f0 irq 14 on atapci1 ata1: at 0x170 irq 15 on atapci1 ad0: 38166MB [77545/16/63] at ata0-master WDMA2 ad6: 14669MB [29805/16/63] at ata3-master UDMA66 acd0: CD-RW at ata1-master using PIO4 acd1: CDROM at ata1-slave using PIO4 afd0: 96MB [32/64/96] at ata2-master using PIO0 Is there a possibility to make the ZIP drive faster ?
