Make your kernel config look like this and recompile/install new kernel. controller wdc0 at isa? port "IO_WD1" bio irq 14 flags 0xb0ffb0ff disk wd0 at wdc0 drive 0 disk wd1 at wdc0 drive 1 controller wdc1 at isa? port "IO_WD2" bio irq 15 flags 0xb0ffb0ff disk wd2 at wdc1 drive 0 disk wd3 at wdc1 drive 1 Then, watch the boot up messages when these device are detected and you should see something like: wdc0 at 0x1f0-0x1f7 irq 14 flags 0xb0ffb0ff on isa wdc0: unit 0 (wd0): <WDC AC34300L>, LBA, DMA, 32-bit, multi-block-16 wd0: 4104MB (8406720 sectors), 523 cyls, 255 heads, 63 S/T, 512 B/S wdc0: unit 1 (wd1): <WDC AC310100B>, LBA, DMA, 32-bit, multi-block-16 wd1: 9671MB (19807200 sectors), 1232 cyls, 255 heads, 63 S/T, 512 B/S wdc1 at 0x170-0x177 irq 15 flags 0xb0ffb0ff on isa wdc1: unit 1 (wd3): <WDC AC22000L>, LBA, DMA, 32-bit, multi-block-16 Notice they say DMA. I do not know if this extends to UDMA support. Smc659@aol.com wrote: > > Im currently using FreeBSD-3.2 stable. How do you get UDMA support working > under FreeBSD?
