Very Computer

I'm still having trouble getting my IDE CDROM to become a device that I
can mount.  Does anyone know what I need to do when I get this message on
startup?  

wdc0: unit 1 (atapi): <NEC                 CD-ROM DRIVE:282/3.04>, removable, dma, iordy
atapi0.1: unknown phase

Enclosed below this message is the rest of the "dmesg" output in case it
helps!

As far as I can tell, i have both IDE Hard Disk and CDROM on the same
controller configured correctly.  The original setup was HD on controller
0, and CDROM on controller 1.  I moved the CDROM to controller 0, and
jumpered it as a slave.  I'm assuming that the HD is a master because NT
and DOS still recognize them when I dual boot.

Should I include my kernel configuation file???
Thanks for any help!

I get exactly the same msg. I am just ignoring it... I have been able
to mount the cdrom... It has been working fine for me. I would also
like to know if I could rectify this msg.

That's because not all IDE drives are fully ATAPI compatible, even if it
says ATAPI, especially drives that are below 4X.

The newer IDE CD roms, 4X and 8X tend to follow to ATAPI standard more
closely than the old ones.  That's why you will have a better chance of
getting a new CD drive to work than an old one.

I also have my cdrom mounted as slave.

In your kernel config file, make sure you've disabled wd1 ( second hard
disk, first
IDE controller ) or it will fight with the wcd0 driver for control of
the CDROM:

# comment me out!
# disk            wd1     at wdc0 drive 1

  Basically it is a timing problem. The CD-ROM indicates that it has
  something for your computer, but it doesn't set the phase correctly
  until a little while after. So a simple delay loop until the phase
  gets itself sorted out works wonders. There are other problems with
  the audio support, but it has nothing to do with this :)

Hmmmm....  The CDROM I have is a newer one.  Either a 6 or 8x by NEC.  I
can't seem to ignore the phase problem though because I can't find a
device for it.  When I try to mount wd1, it says that it's not
configured.  What's the correct device name assuming that I can ignore
the phase problem?

thanks!

I've temporarily given up on my NEC CDROM that came with the Dell and took
my Mitsumi off my Micron Pentium Pro just to see if it was the CDROM
itself and not my configs, wiring, or jumpers that gave me the problems.
It appears to be working perfectly now.  The only problem is that I don't
want my 8x CDROM sitting in my experimental Dell where I plan to do UNIX
stuff that isn't multimedia strained.

It would be great if you could post the patch.  Is it difficult to insert
the patch?  So I would have to recompile the kernel?

thanks in advance,
Kelvin

:   This problem is caused by older "cheap" CD-ROM Drives, but there is
:   a work around. I submitted a patch to the author of the driver. I am
:   not sure if it has made its way in to the FreeBSD tree yet. If
:   people want it. I can post it.

Actually leaving in wd1 is fine so far.  It just probes it after the
wcd0 is configured.  I guess my next question is since both CD-ROM and HD
are sharing the same EIDE controller bus, is there going to be much of a
performance degradation with bus arbitration, or is the bus pretty quiet
when one device isn't doing anything?  I can't imagine how DMA figures
into the complexity of all of this.

Explanations!??
