[Sheflug] Dell X200 and Redhat 8.0



Dear All,

I have just acquired a Dell Latitude X200 and want it to work (more or
less) under Redhat 8.0 (or any other distribution). The main problems
are getting the internal modem and the CD-RW to work.

I have installed redhat 8 with 2.4.18 kernel using an external USB
connected CD drive. The only problem (other than not being able to
install from the machine's CD-RW) was that I couldn't use the graphical
installer.

I'll start with the modem first.

I have installed the pct-0.9.6 driver from Jan Stifter and used minicom
to test the modem. I have successfully managed to connect to Freeserve
(I get a message like CONNECT 46999) but then shortly afterwards get a
NO CARRIER message. I understand that this is a known bug in the driver
but that it's believed to be ISP dependent. Does anyone know if
freeserve could be the culprit and if so could someone recommend another
ISP (I'm currently paying £14/mth for unlimited use). BTW the modem is
an Intel 82801CA/CAM AC'97.

Now the CD-RW.

I opted for the X200 media slice with a floppy and CD-RW connected via
firewire. The floppy works fine and during boot up, Linux recognises
when the machine has been undocked/docked (although I don't think it
does without a reboot). Redhat 8.0 installs the modules 1ee1394,
ohci1394 and sbp2 amongst others. It seems to recognise that there is a
CD drive but I can't mount it.

Sorry for a lengthy first email but I'm totally fed up with this and
running out of ideas.

Thanks,

Nicola.

P.S. Here are some screen dumps
