IDE Autochanger CD's, Any drivers

Post by Terry Collin » Thu, 07 Aug 1997 04:00:00

Hello Folks

Have an NEC CDR-4300 IDE autochanger CDrom drive.
Works fine for the first platter under Linux, but I'm looking to make use
of the other three. Does anyone know of any drivers, or switching stuff.

Can not get it to work by doing the umount, front panel button select,
mount sequence. It just doesn't like it.

1. New IDE-CD/extended IDE driver supports Sony 55E ATAPI CD-ROM!

I'm now successfully using my Sony CDU-55E CDROM drive (an ATAPI drive)
from Linux.  I'm using 1.1.75 plus the ide/ide-cd patch by Mike Lord and
Scott Snyder.  I understand that this code is now part of 1.1.76.  Cool!
This means that just about all my stuff is now supported by "standard Linux".

There are some rough edges.  As mentioned in the README.ide file in
/usr/src/linux/drivers/block, the mount command for the cdrom must be
just right; if a block size other than 2048 is used (or block size
isn't specified, weird errors result).  I initially thought this meant
it didn't quite work.  However, given the exact commands mentioned in

        ln -sf /dev/hdc /dev/cdrom
        mkdir /cd
        mount /dev/cdrom /cd -t iso9660 -o ro,block=2048

I am now successfully reading CDROMs.

Some folks mentioned that they got the older NEC-260 driver to work
provided they'd booted DOS first and used LOADLIN; I'm booting from
LILO and everything works fine.

Note that this drive isn't mentioned in the README.ide file.  Anyone
documenting this, please add the Sony 55E to the list of drives it
works with.

Thanks to all who sent me mail, and especially to Scott Snyder for writing
ide-cd.c !
