In the following, I'm going to describe how to install Debian GNU/Linux 5.0 (lenny) on a HP Compaq nc4000 notebook. This page only contains nc4000-specific information and should therefore be read together with Debian's more general installation guide.
Please note that I no longer own a HP Compaq nc4000 notebook, so I won't provide further updates to this page.
There are multiple ways to install Debian. The most convenient method is probably net booting via PXE. Alternatively, you can boot from an USB CD-ROM drive if you have the docking station with a CD drive or an external USB drive. Finally, it is also possible to boot from an USB memory stick.
Installation via the net using PXE
In order to perform the installation via booting from the net using PXE,
you first have to configure a PXE server. Joe Nahmias wrote a good summary
about this, and there is a wiki entry with more
information. Once you have a PXE server to boot from, you have to
configure your laptop to enable net booting. When you boot, press
get into the BIOS. Then, select
Device Security and
Internal Network. There, you have to enable
adapter boot and set
PXE. After you've enabled PXE, you'll be able to select
Notebook NIC when the nc4000 asks you where to boot from. If your PXE
server is configured properly, it will be found automatically.
Installation from a CD
First, you have to download a CD image with Debian on it. Torrents are available. Once you have
a CD with Debian, you can boot from your USB CD-ROM drive. For this, you
have to first turn
Enable USB Legacy Support on in your BIOS. You will
then have the choice to boot either from the laptop hard drive or from the
USB CD-ROM drive.
Booting from USB memory stick
Aleksandr Koltsoff wrote that he was able to boot from a USB memory stick. He said that you have to do some trickery:
- instead of partitioning the flash, you make the msdos-filesystem directly on it (/dev/sda instead of /dev/sda1).
- then run syslinux on /dev/sda
(or whatever the memory stick is instead of
The nc4000 has a Broadcom NetXtreme BCM5705M chip which supports Gigabit
Ethernet (10/100/1000). The Linux kernel includes the
tg3 driver for
these types of chipsets.
The laptop has an ALi Corporation M5451 audio chip which is supported by
Linux. By default, ALSA will be used and the
snd_ali5451 module is
The nc4000 features a ATI Radeon IGP 340M graphics chip. As far as I know,
this chip is also known as Mobility U1. During the installation, X.org
will be installed and it will automatically work, using the
Both the touchpad and pointer stick work without any problems.
Aki Mimoto mentioned that you can also get the 7 special buttons on the
upper side of the keyboard to work. Simply add the following lines to your
keycode 160 = F21 keycode 174 = F22 keycode 176 = F23 keycode 136 = F24 keycode 248 = F25 keycode 138 = F26
(160 = cpqmute, 174 = cpqvoldown, 176 = cpqvolup, 136 = cpqpresentation, 248 = cpqwireless, 138 = cpqlock)
USB works without any problems.
The Linux 2.6.26 kernel shipped in Debian lenny has the
ath5k module with
which wireless works without any problems. You don't need any binary
firmware to use wireless.
ACPI correctly reports the battery status as well as information about the fans. Frequency scaling is done automatically.
Fabian Kneißl pointed out to me that the Radeon IGP video chip has a power-saving feature known as PowerPlay which can be activated in X.org with the following line:
Option "DynamicClocks" "true"
You can use my info/xorg.conf file and save
/etc/X11/xorg.conf. You should see the following in
/var/log/Xorg.0.log when starting X:
(**) RADEON(0): Option "DynamicClocks" "true" ... (II) RADEON(0): Dynamic Power Management Enabled
You can use
s2disk to hibernate your system (i.e. to write the content to
disk and power it off). Suspend to memory does not work on the nc4000.
Not tested. Bdale Garbee said he got it to work.
It works without any problems. All modules are loaded automatically.
Michael Rasmussen pointed out that laptop-mode-tools is a
useful package for laptops. The package contains several userland scripts
that can be used to save considerable battery power. By default, this
package remounts your partitions with the
noatime parameter when you are
on battery. Unfortunately, this breaks mutt, a popular e-mail client.
Please be sure to read through the documentation of this package and to
look at the configuration file,
- Aleksandr Koltsoff told me that memdisk (a program to boot e.g. from a floppy image via the network) does not work; interestingly, I observed the same so this seems to be a bug in the nc4000. Aleksandr observes that "there's definitely something fishy about the BIOS since for example using memdisk with syslinux doesn't work on nc4000, although on nc6000 it works as expected."
- When the laptop is in the docking station and I connect a USB memory stick during bootup, the system freezes hard.
