I just installed an IDE drive into a SCSI system running
dmesg reports finding device "ad0" which is the right drive. However,
when I went into /stand/sysinstall to fdisk/label the drive my drive
options where da0 (my scsi disk), ad0, and wd0. As far as I can tell,
ad0/wd0 are the same disk.
Also, wd0 is *no where* in my kernal. For that matter neither is ad0,
just the ATA/ATAPI disk stuff...
# ATA and ATAPI devices
device ata0 at isa? port IO_WD1 irq 14
device ata1 at isa? port IO_WD2 irq 15
device atadisk # ATA disk drives
device atapicd # ATAPI CDROM drives
device atapifd # ATAPI floppy drives
options ATA_STATIC_ID #Static device numbering
#options ATA_ENABLE_ATAPI_DMA #Enable DMA on ATAPI devices
It seems to work just fine as ad0, but I was curious why both were showing
