I have FreeBSD 5.3-BETA5 and 5.3-BETA4 installed on separate disks of the same computer. After the installation I added a second floppy drive (disk B in DOS). See following logs about how both systems work after that: dmesg and shell logs of 5.3-BETA5 (two /dev/fd0 device files): PNP0700: adding dma mask 0x4 PNP0700: adding io range 0x3f2-0x3f5, size=0x4, align=0 PNP0700: adding irq mask 0x40 pnpbios: handle 12 device ID PNP0700 (0007d041) [snipped] fdc0: ic_type 90 part_id 80 fdc0: <Enhanced floppy controller> at port 0x3f0-0x3f5 irq 6 drq 2 on isa0 fdc0: ic_type 90 part_id 80 fdc0: [MPSAFE] fdc0: [FAST] fd0: <1440-KB 3.5" drive> on fdc0 drive 0 fd1: <1440-KB 3.5" drive> on fdc0 drive 1 > ls -il /dev/fd[0-9] 73 crw-r----- 1 root operator 4, 10 Sep 24 20:21 /dev/fd0 73 crw-r----- 1 root operator 4, 10 Sep 24 20:21 /dev/fd0 dmesg and shell logs of 5.3-BETA4 (no such bug): PNP0700: adding dma mask 0x4 PNP0700: adding io range 0x3f2-0x3f5, size=0x4, align=0 PNP0700: adding irq mask 0x40 pnpbios: handle 12 device ID PNP0700 (0007d041) [snipped] fdc0: <Enhanced floppy controller (i82077, NE72065 or clone)> at port 0x3f7,0x3f 0-0x3f5 irq 6 drq 2 on isa0 fdc0: FIFO enabled, 8 bytes threshold fd0: <1440-KB 3.5" drive> on fdc0 drive 0 fd1: <1440-KB 3.5" drive> on fdc0 drive 1 > ls -il /dev/fd[0-9] 32 crw-r----- 1 root operator 242, 0 Sep 24 19:05 /dev/fd0 34 crw-r----- 1 root operator 242, 1 Sep 24 19:05 /dev/fd1 P.S. having two floppy drives became rare at our days but this is still possible and correct to be used by anyone. __________________________________ Do you Yahoo!?
