>&#13; Most notebooks today come with CD drives. If floppy and CD drive are
swappable they are usually mutually exclusive, however many vendors (HP,
Dell) provide cables which allow the floppy module to be connected to
the parallel port. Sometimes the CD drives comes as external

CLASS="acronym"
>PCMCIA</SPAN
> device (e.g. SONY), or as SCSI device (e.g. HP
OmniBook 800), USB device (e.g. SONY), or as Firewire (e.g. SONY VAIO
VX71P). Such an external devices might bear problems to install Linux
from it.

>&#13; As far as I know there are SONY DiscMans available which have a port to
connect them to a computer or even a SCSI port. I found an article
published by Ziff-Davis Publishing Company (September 1996 issue, but
missed to note the URL) written by Mitt Jones: "Portable PC Card CD-ROM
drives transform laptops into mobile multimedia machines", which listed:
Altec Lansing AMC2000 Portable Multimedia CD-ROM Center; Axonix ProMedia
6XR; CMS PlatinumPortable; EXP CDS420 Multimedia Kit; H45

Some notebooks come with an external CD drive, you need an extra cable
to connect the sound output of the drive to the sound input of the
notebook.

The internal usually work, see

for details. But with the different external (PCMCIA, Firewire, USB) drives you probably need
some tweaking.

: "UDF is a newer CDROM filesystem standard that's required for
<SPAN

>DVD</SPAN
> roms. It's meant to be a replacement for the
ISO9660 filesystem used on today's CDROMs, but the immediate impact for
most will be DVD. <SPAN

filesystem to contain MPEG audio and video streams. To access

cdrom drive, the kernel driver for the cdrom drive, some kind of MPEG
video support, and a UDF filesystem driver (like this one). Some
<SPAN
CLASS="acronym"

ISO9660 filesystems. In that case, you could get by without UDF
support."
