I might suggest using FreeBSD 4.0-CURRENT if that's not a production Box. It has a new ATA driver that might work. you may want to repost the original message and ask if there are known problems, I would've thought that if you got BIOS to use it properly, FreeBSD would've gotten it to work too. This is a dmesg output for my computer to show you what the ata driver detects as: ata-pci0: <Intel PIIX4 IDE controller> at device 7.1 on pci0 ata-pci0: Busmastering DMA supported ata0 at 0x01f0 irq 14 on ata-pci0 ata1 at 0x0170 irq 15 on ata-pci0 ad0: <Maxtor 90845D4/GAS54112> ATA-4 disk at ata0 as master ad0: 8063MB (16514064 sectors), 16383 cyls, 16 heads, 63 S/T, 512 B/S ad0: 16 secs/int, 0 depth queue, UDMA33 Creating DISK ad0 Creating DISK wd0 ad1: <Maxtor 84320D4/NAVX1920> ATA-3 disk at ata0 as slave ad1: 4120MB (8438850 sectors), 8930 cyls, 15 heads, 63 S/T, 512 B/S ad1: 16 secs/int, 0 depth queue, UDMA33 Creating DISK ad1 Creating DISK wd1 ad2: <FUJITSU MPC3064AT/6020> ATA-3 disk at ata1 as master ad2: 6187MB (12672450 sectors), 13410 cyls, 15 heads, 63 S/T, 512 B/S ad2: 16 secs/int, 0 depth queue, UDMA33 Creating DISK ad2 Creating DISK wd2 acd0: <CD-ROM 40X/AKU/U30> CDROM drive at ata1 as slave , 128KB buffer, PIO acd0: supported read types: CD-DA acd0: Audio: play, 255 volume levels acd0: Mechanism: ejectable tray acd0: Medium: CD-ROM 120mm data/audio disc loaded, unlocked That's the full output from a dmesg. If you think this driver would help you, go ahead and upgrade to -CURRENT, but be careful, this driver is beta. I'm also not sure that the wdc driver knows about your harddrive controller, I don't think anyone has done anything for the chip that AMD supplies with the K7 yet. ================================================================= | Kenneth Culver | FreeBSD: The best OS around. | | Unix Systems Administrator | ICQ #: 24767726 | | and student at The | AIM: AgRSkaterq | | The University of Maryland, | Website: (Under Construction) | | College Park. | http://www.wam.umd.edu/~culverk/| ================================================================= On Tue, 5 Oct 1999, Stephen Roome wrote: > On Mon, 4 Oct 1999, Kenneth Wayne Culver wrote: > > Well, with your setup with the cyls and heads and all, you have to make > > sure that your custom kernel thinks you are using LBA, Generic actually > > doesn't use any flags at all, what I would suggest doing (if you havn't > > already) is taking all flags off the wdc0 and wdc1 devices, and step by > > step adding each one in until you get a problem; then you will be able to > > pinpoint the problem if it is with the flags.
