Linux RedHat 6.2 on Notebook:
This document provides a description of the installation and configuration
of Linux RedHat 6.2 on an IBM ThinkPad A20p notebook computer. It can serve
as a guide for setting up your own A20p system, a reference for setting
up aspects of other machines with similar hardware.
IBM ThinkPad A20p Model 2629-6SG
The ThinkPad as I ordered it came with the following specifications:
CPU: Intel Pentium III 700Mhz SpeedStep Technology
RAM: 128MB SDRAM
Storage: 17.0 GB
Display: 15.0" TFT (1400x1050)
CDROM: Internal 6xDVD Typ Matshita SR-8174 RPC-2
Floppy: Internal NEC
Sound: Crystal SoundFusion PCI Audio
Modem: Xircom MPCI+Modem 56 WinGlobal
LAN: Intel PRO/100+ MiniPCI
Pointer: TrackPoint w/ 3 buttons
PC Slot: two Type I or Type II, or one Type III
Interfaces: Serial, Parallel, Monitor, S-Video, USB, IR
Size: 12.97" x 10.66" x 1.69"
Battery: Li-Ion 58 Wh, 10.80 V (Panasonic)
If you have more hints, write me
The ThinkPad came with Windows98SE installed, and though I tend towards
the extreme side of Linux zealotry I decided to leave the beast installed
for the time being so I could watch DVD's and use the Hibernation. For
all Partitioning issuses i dicided to use PartitionMagic 5.0x from DOS.
So I shrank the Windows partition down:
WIN98 - 4 GB
/ - 12,7 GB
/boot 128 MB
swap - 128 MB
I installed RedHat 6.2
with server option. So X will not be started at setup. Do not use the graphic
setup feature. The screen will remain blank after installation, and the
There is an error to access the floppy (also after booting from it!).
I'm unable to read / write or mount data to/from the Floppy! (If
you have the same Error, please contact me!)
Installation of PCMCIA Drivers done (autodetect) and running. (Except running
with loadlin from WIN98! Then you will not be able to load the PCMCIA Module!)
The A20p uses the ATI Mobility 128 AGP video card. Support for the ATI
Mobility 128 cards is *NOT* included in XFree86 as of version 3.3.6,
and support is *NOT* available in binary distribution of Xfree86
4.0. However, if you run XF86Setup, it`s unable to find a apropriate card.
FrameBuffer Support solution (XFree86 3.3.6)
To running X (very slow) i had to enable Framebuffer support. Use kernel
option "vga=834" (1400x1050x16). Installing the XSERVER "XF86_FBDev" and
generate an configuration with "xf86config" and replace the /etc/X11/XF86Config
file by this
After this, you have to replace the link to the XServer. Just do "rm /usr/X11R6/bin/X
; ln -sf /usr/X11R6/bin/XF86_FBDev X".
Accelerated r128 FB solution (XFree86 4.0.1)
To get fast accelerated FB support of your A20p (1400x1050) see
Lingevitch's Page for helpfull tips. It's working, and realy fast.
Here is the XF86Config
file, to get 1400x1050x16 with vga=834 in lilo.conf! Or 1400x1050x24 with
vga=835 in lilo.conf! Use Binary-Distribution
of official XFree86 4.0.1 release.
The A20p comes with a Crystal SoundFusion PCI soundcard. Using the ALSA
snd-card-cs461x modules. Compile it with "./configure ; make install".
First you must disable "PCI Bus Power Mgmt" in BIOS menu. Push [F1] at
startup, and disable <Config> - <Power> - <PCI Bus Power Management>
(last entry, scroll down!). Otherwise you are unable to play files using
More hints you find here
from Alan Shutko.
Tha A20p includes a Xircom Modem MPCICard with PartNO: MPCI3A56GSP-100PA.
This device works great with the Lucent
WinModemDriver. Just download the file, unpack with unzip and start
./ltinst. If its not able to find the devicelink, remove the module by
./ltuninst and redo ./ltinst.
I have not yet had a chance to test the USB port, as I have no USB devices.
If anyone has info on this, let me know and I'll update this site.
Apm is giving a correct load of my battery. apm -s working very well. For
wakeup use [Fn] and when see garbage on the screen just move the mouse
a little bit, and the desktop is ready again!
Hibarnation with running X-Server will result in unusable X-Desktop
I'm using the following RedHat Kernel-RPM: kernel-2.2.16-3.i686.rpm
with this config.
