big Linux-supporter and most of their hardware is supported. That's
why thinkpads are probably the best choice for running Linux on a
laptop. Let's go through it in detail.

IBM Thinkpad 765L
Model number: 9547-X9J
List of hardware:
CPU: Intel Pentium 166 MMX
Chipset: Intel Corporation 430MX - 82437MX
Intel Corporation 82371FB PIIX
Memory: 64MB RAM, 100 MHz, non-parity, 64-bit SDRAM SO DIMM memory
Hard disk: 5 GB IBM ATA DISK, IBM-DADA-25120
CD-ROM: SANYO CRD-S372B ATAPI CD-ROM
Video: Trident Microsystems Cyber 9397, 2Mb RAM
Soundcard: Crystal 4232 Chip
PCMCIA: Texas Instruments PCI1250
Internal modem: ACP (MWave) modem
Screen: 13.3" TFT Display
Installation of Red Hat 7.1 didn't give me any unusual problems, the
sound card didn't run off the shelf but it was really easy to get to
work (read on...).
Please note that if a graphical installation with your distribution
does not work, you can always try to install it text-based if possible.
To avoid problems with booting large harddisks, please use a recent
version of LILO
with large hard
drives and that doesn't have the 1024 cilinder limitation for
The nice thing about Linux is that you can configure your kernel exactly to fit
your hardware and since kernels improve very fast, you can keep up with the
latest features of the kernel as soon as they arrive.
The general rule of thumb is to use the latest stable kernel. The 2.4-series
work fine and the stock Red Hat kernel has everything you need.
To compile a kernel for your system, you should check the
The configuration of X works automaticaly for several distributions. If you
have troubles, remember that the 2Mb of memory on the card only allows you
to use 1024x768 with 16bit colors.
On these types of thinkpads the key-combination Fn-F7
allows you to
switch from your LCD
to an external monitor or both. (Three phases) This
however leaves your
X in the same resolution as on your LCD, which is lower than the capablities
of your external monitor. At this time however, you need to restart your
X-server to change the resolution. Work is in progress to overcome this
allows you to boot with an external monitor by default.
The drivers you need to load are: cs4232
modprobe cs4232 io=0x530 irq=5 dma=1 dma2=0 mpuio=0x330 mpuirq=5
modprobe opl3 io=0x388
APM seems to work without problems.
You can suspend your laptop by pressing Fn-F4
check your BIOS for additional configuration.
is supported and will most probably work off the shelf with your
distribution. But if you have build your own kernel you need the right drivers
for your PCMCIA-devices. To get more information about PCMCIA-drivers and how
to configure them, check the
The laptop comes with an ACP (MWave) modem. (A WinModem avant la lettre)
Fortunately, IBM is working on an Open Source driver, which already works.
At the time of writing it isn't included with the kernel yet, but only time
will change this minor problem.
You can find the module and more information about winmodems on the
If you used the kernel-config above, you're able to use the VESA
by adding the following lines to your /etc/lilo.conf
Here's a list of different modes:
| 640x480 800x600 1024x768
256 | 0x301 0x303 0x305
32k | 0x310 0x313 0x316
64k | 0x311
If you want to use the faster text-mode with smaller fonts (80x60) then you can simply use:
If you used the kernel-config mentioned above, just link /dev/mouse
and load the following modules usb-uhci
I'm using journaling filesystems on most of my systems nowadays. I use ext3 because at this
moment I don't trust neither reiserfs and XFS nor JFS or included in the kernel. And
Red Hat comes by default with all the tools to use ext3 (although I've build a newer
e2fsprogs package myself).
You don't really need a journaling filesystem, but occasionaly you find your machine
locked up because it ran out of power or because you were experimenting a bit too much.
And then you will enjoy a journaling filesystem more than ever.
Some settings allow to use both your trackpoint and an external mouse at the
same time without a problem. TODO
There is an alternative to configure your BIOS (much like tpctl under DOS). TODO
IBM released some BIOS updates, unfortunately these updates are
distributed as DOS
or Windows executables which is a pain for Linux users. It would
be nice of IBM to just distribute the images created by these
disks so users of other platforms can upgrade their BIOS without
needing DOS or Windows.
For your convenience we've put the image online:
Only update your BIOS if you really need to.
