Here's an odd one: If I disable the FLOPPY DISK in the BIOS of my ASUS Terminator K7, then FreeBSD (4.8-STABLE) will fail to find the HARD DISK when it boots. More details: Disable floppy in BIOS, try to boot machine. BIOS sees hard disk (primary master, 20GB Seagate) Boot loader loads Kernel loads and boots Kernel finds atapci0, ata0, ata1 But, kernel never sees ad0 and boot freezes at end of device probe. (Kernel issues no error message.) I did this because I pulled out the floppy cable (it was getting in the way of the fan). Curiously, if I enable the floppy disk, then: BIOS reports error (no floppy found) Kernel boots normally, although it does probe and recognize the floppy drive (the floppy drive is physically disconnected!) Apparently, floppy probing is more peculiar than I had ever imagined.... Tim Kientzle
