Hi all,
CD/DVD drive will install system, but not there after install on Lenovo
3000 N200.
Have installed various Ubuntu, same problem. No entry for drive in /dev
list.
Have Ubuntu 7.04 on a desktop, and compared /dev list after install
using same install CD. Would not recognize the drive after Win XP
install as well.

Would anyone know of a work around that may get this working, or am I
committed to
an external CD drive?
Everything else works fine.
Many thanks in advance.
Take Care
Winton

I have the same computer, with the same problem. Booting with
acpi=off will work -- but not the best solution on a laptop. I've tried
every kernel configuration this way to sunday with no avail.

Hi,
I have been told of a possible solution quote below

"When I was setting up my toshiba satellite I came across this
http://gentoo-wiki.com/HARDWARE_Toshiba_Satellite_P100#Linux_Support gentoo articel.
there it says the optical drive needs some kernel command parameter (in this case: combined_mode=libata) to work properly."

Have had 3 suggestions as to where pass this parameter

/etc/modprobe.d/options

/boot/grub/menu.lst and look
for "defoptions"

/etc/sysctl.conf

None of the above work, Any suggestions welcome.

Are you using Etch? Maybe you need a newer kernel than the default
2.6.18. You can get newer kernels suitable for installation on Etch from
www.backports.org or you could try one of Kenshi Muto's updated Debian
installer images (http://kmuto.jp/debian/d-i/).
