	and then, got an error message like:
	/bin/9660srv 200: err stack 1: 114f 1872 3cf3 0 0 0
	and 9660srv died.

looks like a 9660srv bug.

i know nothing about the internals of 9660srv, but i just took
a look and it seems it tries to implement an error stack just as the
kernel does. this error comes out when the stack has not been
completely popped by the time the code gets back to the main loop.
the numbers printed are the PC's of 'waserror' functions in the
code. use acid on the 9660srv binary to find the 'waserror's then
check there are no code paths out which don't have a corresponding
'poperror'.

Thank you for your quck reply.
I also took a reply from Charles, and he suggested me to delete
the block of waserr in getcontin of 9660srv.c.
It solved my InfoMagic CDROM problem.

For an unstability problem of Atapi CDROM in my case is
now undergoing to replace the drive.  I called the reseller
and told them this drive makes extraordinal noize whern
used in a vertical position.  Sometimes it failes to access
CDROM etc., and they replied they could replace the drive.

If someone has CDROM named "InfoMagic Unix CD-ROM"
(January 1994), try to read it.
We cannot read this CDROM by none of our scsi and Atapi
cdrom drives.  We cannot find any scratches on it.
It can be read on our Linux box though.

And tested other more CDROMs..., and found some can be
read, but others cannot.  I cannot see any systematics on
those CDROMs.  The same CDROM can/cannot be read
in different trials.

To identify what's going on, I ran 9660srv with -v option.
The verbose messages are as follows:

mount -c /srv/9660 /n/cdrom /dev/atapi0disk

I'm getting trouble to make a new TEAC CD-532EK atapi drive,
attached to the primary IDE port without any HDDs.
( I have a SVGA card, SB16, and a nic card).

After booting up, I can recognize /dev/atapi0disk.
Then,  dispatched the command
/bin/9660srv,
and got the response of
/bin/9660srv 99: serving /srv/9660

Then, I followed it by the command
mount -c /srv/9660 /n/cdrom /dev/atapi0disk,

and then, got an error message like:
/bin/9660srv 200: err stack 1: 114f 1872 3cf3 0 0 0
and 9660srv died.

What is wrong with my configuration?
