[ I sent this to freebsd-questions but got no response. I'm pretty sure this is a bug (wdc1 OK, wdc0 can't detect disk). ] DEC Celebris 590 (P90) 2 IDE on motherboard (CMD 640B), disabled Promise Ultra33 PCI IDE bus master WD AC24300 on Promise IDE #1 (won't work on motherboard IDE) Toshiba CD-ROM on Promise IDE #2 FreeBSD 3.3 kernel & mfsroot floppies The hardware is all OK: I have NT 4.0 running on this config. Enter CLI kernel config and config both wdc0 and wdc1 as follows: port 0 irq -1 flags 0xa0ffa0ff (have also tried 0xb0ffb0ff) Hardware probe detects both CMD 640B (wdc0) and Promise Ultra33 (ide_pci0). PCI attach says "ide_pci0: adding drives to controller 0: 0 1 2 3". Then: wdc0 not found at 0xfc48 wdc1 found at 0xfc50-0xfc57 (Further messages correctly identify the Toshiba CD-ROM.) As far as I know, these are the correct ports for the Promise (wdc1 is certainly correct because the CD-ROM is found there). FWIW, the BIOS on my motherboard can't detect the WD AC24300 when it's on motherboard IDE #1, although CMD's DOS diagnostic "checkide.exe" can. The motherboard BIOS has a 4096 cylinder (2.1 GB) limit and it's a 4.3 GB drive. Is this a bug in FreeBSD's IDE support? Please e-mail me directly.
