Hi,

I know no-one else has kicked up a rumpus about this, so I assume
that this is a problem with my configuration.  I have a FreeBSD
box that I track -STABLE with.  I don't use my CD-ROM much, but
recently discovered that it isn't working.  In fact, checking
dmesg showed that it isn't being detected.  I haven't changed my
configuration or my hardware.  Any clues?

Relevant evidence, exhibit 1:

[note absence of acd0]

The config file GURNEY still contains:

# ATA and ATAPI devices
device          ata0    at isa? port IO_WD1 irq 14
device          ata1    at isa? port IO_WD2 irq 15
device          ata
device          atadisk                 # ATA disk drives
device          atapicd                 # ATAPI CDROM drives
options         ATA_STATIC_ID           #Static device numbering
options         ATA_ENABLE_ATAPI_DMA    #Enable DMA on ATAPI devices

Hmm.  Looking at that, perhaps I don't need the ATA_STATIC_ID
option, and the associated wires.  I'll give that a try now.

Lastly: I noticed that at boot time, my BIOS claimed to see my
CD-ROM drive.  Unfortunately, I don't run this system dual-boot,
so I can't readily check to see if another OS can see it.  For
what it's worth, the cables seem to be intact, the power is
connected, and the eject button moves the cup-holder in and out.

Any suggestions?  Any more information that I can provide, or
tests that I can perform?
