I keep my /boot/device.hints on this notebook identical to GENERIC.hints. After commenting out "fdc" lines in /boot/device.hints: $ diff -u /sys/i386/conf/GENERIC.hints /boot/device.hints --- /sys/i386/conf/GENERIC.hints Sat Apr 3 13:59:14 2004 +++ /boot/device.hints Thu Aug 26 00:32:55 2004 _at__at_ -1,8 +1,8 _at__at_ # $FreeBSD: src/sys/i386/conf/GENERIC.hints,v 1.13 2004/04/01 21:48:31 alfred Exp $ -hint.fdc.0.at="isa" -hint.fdc.0.port="0x3F0" -hint.fdc.0.irq="6" -hint.fdc.0.drq="2" +#hint.fdc.0.at="isa" +#hint.fdc.0.port="0x3F0" +#hint.fdc.0.irq="6" +#hint.fdc.0.drq="2" hint.fd.0.at="fdc0" hint.fd.0.drive="0" hint.fd.1.at="fdc0" I got this: $ dmesg |grep fdc fdc0: ic_type 90 part_id 73 fdc0: <Enhanced floppy controller> at port 0x3f7,0x3f0-0x3f5 irq 6 drq 2 on isa0 fdc0: ic_type 90 part_id 73 fd0: <1440-KB 3.5" drive> on fdc0 drive 0 The following now works: 1. "kldload fdc" 2. "kldunload fdc" says "Operation not supported". 3. Kernel compiled with "device fdc". All results in a working floppy. The following still doesn't work: "kldload fdc" on a kernel compiled with "device fdc" results in a panic. P.S. If I comment out two "ppc" lines in /boot/device.hints, the ppc0 attaches normally, and there's no phantom ppc1. Cheers, -- Ruslan Ermilov ru_at_FreeBSD.org FreeBSD committer
