It's me again.
When I boot up the kernel, it says:

    "Checking for CD... Unable to identify CD-ROM format.
     no CD found..."

And also this is the EXACT message I get when i type:

darkstar:~# mount /dev/mcd /cdrom  <ENTER>
mount: the kernel does not recognize /dev/mcd as a block        device. (maybe `insmod driver'?)

Maybe now someone can help me. (I need that darn CD!)

Thanks, Bromone4

Two things:

1. Make sure that you /dev/mcd matches your CD-ROM type.  The newer CD-ROM are IDE drives, so they go under /dev/hd?.

2. If /dev/mcd is really what you want, make sure you recompile your kernel to include support for MCD CD-ROM drives.  This is most likely the problem, since the kernel doesn't recognize the device.  If you are not familiar with compiling the kernel, see the CD-ROM HOWTO and the Kernel HOWTO at:

I need more adequate help than that. I have lots 'o' stuff on CD,
including WINE, and well, other junk. (Doom2, QUake...).

It seems that you should not be using /dev/mcd?  The boot up message says that it actually recognize the CD-ROM but found no CD in it (I hope you have put a CD in), where as mount /dev/mcd tells you that it doesn't recognize it at all.

In my slackware 3.1 setup, here are the different devices that the startup script tries to find a CD-ROM (see /etc/rc.d/rc.cdrom):

scd0 scd1 sonycd cdu535 mcd sbpcd aztcd cm206cd gscd0
mcdx0 mcdx1 optcd0 sjcd lmscd hdd hdc hdb hda hde hdf hdg hdh

(append a /dev/ to each of them.)  Try them one by one to find out which one is your CD-ROM (you can skip one of the hd's that corresponds to your hard drive if you want).

Also, make sure that when you use mount, do:

  mount -t iso9660 /dev/whatever /cdrom

so that mount knows that it is looking for a CD-ROM format.

Which brings me to a second idea.  Make sure that your kernel supports the ISO 9660 format.  If not, you will not be able to read standard CD-ROMs.  You can try the above mount command, and the kernel should complain if it doesn't support iso9660.  If that's the case, you have to recompile your kernel.

If that still doesn't work, make sure that you can read the CD-ROM from another OS, say DOS.  Hmm.. I just realize that you are running on UMSDOS.  I have never used UMSDOS, so I don't know how that will affect things.  From what I can see in the UMSDOS HOWTO, it shouldn't have much effects, but I wouldn't know for sure.

In your comment (since I only get it from email, I'll include it here):

I really think that UMSDOS has many things to do with it.  Once before I had RedHat 3.0.3 with Kernel 1.2.xx and 'mcd' worked fine. I had no troubles, but also I had it on its own partition.(1.5 gig).

By the way, i am also having trouble with DIP. I can't login to the net! (now I am using Win95). I need to download things (eg. sQuake) in Linux format. (I tried in Win95. tar don't work there) so anyways, i hope you can help me there also. Here is the error message using a modified /usr/doc/dip/samples/sample.dip script (reproduction not exact):

<CODE> Failed at waiting for Password entry... </CODE>

or i don't know.

also when i installed Slackware 3.1, I used mcd=0x320,11.
so shouldn't that be in the Kernel already? just a thought.

---

Whether the driver is included in the kernel depends on which kernel you used.  The kernel I had from Slackware 3.1 did not recognize my CD-ROM at all until I recompile the kernel.

As for the dip, can you set up a new question and post your dip script?  Posting what you usually get in a manual login (login prompts, etc) would help.
