Very Computer

Hi there! I have a problem concerning my CD-ROM under Linux, the drive is
a Funai 2-speed and it uses its own controller card.

Here are the specs;
FUNAI 2x
on it reads;    NSA Model; NSCD-2X-P1
                Nissei Sangyo America Ltd.
                100 Lowder Brook Drive
                Westwood, MA020909
                May 1995
On the controller card I found these marks;
                Copyright Creative Technology
                CT1810
[end of specs]

Here's what happens when I boot DOS;
config.sys:     E252X/E282X CD-ROM Device driver Ver1.07
                (c) FUNAI ELECTRIC CO LTD 1993-1995
                i/o port: 0250  i/o mode: P10
                ID: E2520 0.01
[end of dos config.sys]

When I try to boot Linux with the bootparameter hdc=cdrom
INIT echoes;    ide1: secondary interface on irq 15
[end of INIT echo]
but the dmesg gives me this;
                hdc: no response (status = 0xff)
                hdc: ATAPI cdrom
[end of dmesg echo]

My system is a 486/66 20Mram w/ Linux -slackware 3.1? -kernel 2.0.21
I have tried with the soundblaster and other drivers but they don't seem
to notice any drive at all...
Um, I HAVE read the faq's and HOWTO's  ;)
This is what I know of my drive and what it does, I'm kindo' stuck here,
I don't like booting up DOS every time I need the drive ;)
Could someone PLEASE help me????
I could ofcourse BUY a new drive that is a 'real' IDE-drive but I
don't think that's the Linux way of doing it !! ;)
[end of humble-bumble ;)  ]

I have the identical drive :(  except I don't see the word Funai anywhere
on the drive, the brand is marked NSA, but the model NSCD-2X-P1. It seems
as though mine MAY be set up slightly different than yours: For one thing
the I/O port is different, (then again I think my controller card is
different: some generic thing with the only marking being CD338), mine is
0x340, no mention of the CD being on the IDE port, (which on my card is
jumpered to "disable"). The CD rom is on the connector marked Panasonic,
(the others, are IDE, Mitsumi, and Sony).

Well I hope you have better luck than I have been. Hopefully someone will
answer these messages with some info that could help...

I'm not completely uninitiated to writing device drivers, (played with it
a little in DOS), but I really never tried to do anything like that with
the CD drive. I'd actually be quite curious to know what kind of
information is out there for this drive. Perhaps the people to contact
are the folks who distribute Funai/NSA?

After installing slackware 3.0 from the Infomagic CD, I got the
kernel release 2.0.0. and everything (a lot) worked, especially my
SONY CDU31a CD , mounted as device /dev/sonycd. After that I tried to
upgrade my kernel, first to 2.0.21, then to 2.0.23. Both times, the
kernel could not mount my cdrom, saying something about
"unknown block device".
I definitely added support for my CD Rom (it is specially asked by
config). The mount command is
"mount -t iso9660 -o ro /dev/sonycd /cdrom"
(worked with 1.2.13 and 2.0.0 - slackware).

Has anybody got an idea, what's wrong ?

Thanks in advance

You need to read the documentation for the CDU31A driver.  Linus requested
that the driver *stop* autoprobing for the drive, as that was causing problems
on some systems.  Therefore, you *must* tell the kernel where the drive is.
If the driver is compiled in the kernel, you specify the address by using
the append= feature of LILO.  If the driver is a loadable module, you need
to create a file in /etc named (from memory) conf.module, where you then
tell the module where the drive is.
