There are plenty of questions in the archive on the website, but not
many answers.  My ATAPI IDE CD-ROM is configured as master on the
secondary line, and I have enabled ATAPI and wcd0 in my kernel
configuration file, and rebuilt the kernel:

> controller	wdc0	at isa? port "IO_WD1" bio irq 14 vector wdintr
> disk		wd0	at wdc0 drive 0 
>
> controller	wdc1	at isa? port "IO_WD2" bio irq 15 vector wdintr
> disk		wd2	at wdc1 drive 0 
>
> options	ATAPI
> device	wcd0

I've done some debugging and inside the wcdattach() call,
atapi_request_immediate() is returning 1: the operation failed.  So
the atapi code to check what kind of device it is is returning 5
(CDROM), it just isn't able to *talk* to it.

I have a Hitachi FX400 IDE quad speed drive, on a brand spanking new
"Clincher" PC (Intel Pentium at 99Mhz and all).  Not a spec of SCSI
anywhere on the machine.  I'm using 2.1.0-RELEASE.  Any and all help
greatly appreciated,
