CD-RW IDE Freecom con PCMCIA

Post by JJ Bonill » Fri, 26 May 2000 04:00:00



Hola a todos. El problema es el siguiente:

Tengo un CD-RW Freecom IDE que se conecta al portatil mediante un adaptador
PCMCIA. El driver para las Freecom existe y funciona bien (da problemas en
presencia de la PCMCIA Ethernet, pero eso es otra historia), te coloca la unidad
como IDE en /dev/hde y se puede montar perfectamente para leer. Lo que quiero
.. claro, es escribir, para ello pongo la emulacin SCSI para las IDE/ATAPI y
todo eso que explica el COMO de grabacin. Resultado:

La emulacin funciona bin (el CD-ROM me lo pone como SCSI) y esta deteccin la
hace al principio del arranque, luego entran las PCMCIA y al llegar el driver
de Freecom carga y dice que falta el driver IDE de /dev/hde (claro, est
desactivado al compilar el kernel).

1.- Como la deteccin SCSI es previa no detecta el CD-RW que todava no ha
cargado.
2.- ?el driver Freecom PCMCIA admite este proceso?, pensando en cargarlo antes
que la deteccin SCSI.

Como resultado, no puedo grabar en Linux.

Tengo tambien el cable paralelo ?podra por ah?

Gracias. Un saludo.

Sorry, I was referring to the backport of the 2.4 IDE code to 2.2.
I'm currently using ide.2.2.19.05042001 successfully, which I got from:

  ftp://ftp.us.kernel.org:/pub/linux/kernel/people/hedrick/ide-2.2.19

I've used several similar patches, though.  Stock 2.4 kernels work
fine with my CD-RW as well; however, I've now discovered that plain
2.2 kernels do not.  This could easily be a long-standing problem,
probably at least a year old - I've only recently stumbled across it,
though.

Since I have a solution (use the 2.4 IDE backport), this isn't
critical; however, since many people still rely on 2.2, and I'd like
to use a stock 2.2 kernel if possible, I'm willing to spend some time
debugging this.

Thanks!

(A bit of background: Before I got my CD-RW drive last summer, I
bought an OnStream DI-30 drive.  This drive was then only supported on
2.2 with the 2.4 IDE backport, and so I've used this drive
successfully with 2.2.16 + 2.4 IDE patch, and a similar combination
since.  Since stock 2.2.19+ now support this drive through the osst
patch, I thought I'd try it out.  It does work, but at the cost of
losing my CD-RW.)
