Daring to challenge the will of the almighty Leviam00se, Matto
(molson@milwaukee.rbvdnr.com) had the courage to say:


: I finally got mine to work last night!  The problem I was having was that
: the boot floppy(and the generic kernel) set the I/O address for the 
: IDE CDROM to something like 0x330.  Thanks to Windows 95(the only thing
: about it I've been thankful for), I could print out my entire hardware
: configuration and found that my CDROM was at I/O 0x630.  I changed this 
: using config on booting the ATAPI floppy and the install went great.  
: Then I used config on the generic kernel and it found it just the same.
: The only thing left to do was mount it.

: In CONFIG(to set address):
: config>port matcdc0 0x630  //or whatever your I/O address for IDE CDROM
: config>quit

Uhm, pardon me for barging in here, but I feel compelled to point out
that this is _NOT_ an IDE/ATAPI CD-ROM. If your computer salesman or
documentation identifies it as on, they're wrong. This is a
Panasonic/Matushita CD-ROM. I have one too, at the same I/O address even:

matcdc0 at 0x630-0x633 on isa
matcdc0 Host interface type 1
matcd0: <CR-5630.75>  

The actual drive happens to be a crufty Panasonic CR-563 double speed
device, which is puny by today's standards but I don't care so long
as it works. The controller is a 'Packard Bell' (actually Aztech)
combination audio board/CD-ROM controller which actually supports
three types of CD-ROM interfaces (it does Mitsumi and Sony too). I
ended up having to steal the matcd driver from 2.1 and compiling a
kernel with 'options AUTOHUNT' so that it would search all of the
possible I/O addresses defined in its table, of which 0x630 is one.

Anyway, you don't need the ATAPI boot floppy for this drive. The stock
one will work just as well. Unfortunately, I'm not too familiar with
actual ATAPI drives in general (the few I have access to all worked
when I tested them with pre-2.1 SNAP kernels) so I can't offer any advice
to the original poster, other than to keep trying.
