Linux on the Toshiba Satellite TE2100

Preface

This is a survey about Linux related hardware features of the Toshiba Satellite TE2100.

Installation

On my TE2100 I have installed the Debian Linux distribution.
Currently I am using sid/unstable
I initially installed Mandrake 8.2 (had some cd’s handy) and it booted/installed first time, no problems

Hard Disk/DVD-ROM

30GB IDE with the unmask_irq, dma and 32-bit I/O support turned on. Use the following command to set this up

hdparm -d1 -u1 -c1 -m16 -X66 /dev/discs/disc0/disc

By doing this I went from 3.11MB/s to 22.15MB/s transfer speed

The DVD supports dma, unmask_irq and 32-bit I/O as well

hdparm -d1 -u1 -c1 /dev/cdroms/cdrom0

Note: the above commands are for people using devfs, other wise you use /dev/hda for the HD and /dev/hdc for the DVD

Ethernet

Intel Ethernet Pro 100
Supported by the eepro100 or e100 kernel module, I use eepro100 since has less licensing ‘difficulties’

PCMCIA

Works wonderfully, I have a Avaya silver 802.11b card (11Mbps) that is supported by the orinoco_cs module.
‘cardmgr’ recognizes the card straight off and starts it up automatically (DHCP to the rescue)

Graphic-Chip

Nvidia GeForce4 420 Go chipset
Supported well by the binary Nvidia drivers, supported by standard XFree86 nv driver since 4.3.0 (2D only) but for earlier versions you may need to use vesa driver for the initial install. My XF86Config-4 is available here
If you are having problems with there being a black border down the right side of the screen add the following lines to your /etc/modules.conf (some may already exist)

	alias /dev/nvidia* nvidia
	alias char-major-195 nvidia
	options nvidia NVreg_SoftEDIDs=0 NVreg_Mobile=2

Keyboard

Originally I had problems with the keyboard in XFree86 in that when I typed quickly it would recognize each key twice. This is fixed by adding the following line to your XF86Config-4 file into the ServerFlags section

Option          "XkbDisable"    "true"

APM

APM suspend works fine if you are not running X, but if you need to suspend from X you will need to modify the nvidia kernel module as below

  1. Grab the sources to the latest nvidia driver (modification works for older versions as well) and search for a file named nv.c once they are extracted. Go to the directory containing that file.
  2. Open nv.c in your favourite editor and search for “APM”
  3. In the lines following this look for “return 1;” in that subroutine (anywhere up to the second #endif)
  4. Change each instance to “return 0;”
  5. Save the file, exit then run “make install” and watch the magic

Note: This works for me even with AGP turned on YMMV

Example:

Before

default:
	nv_printf(NV_DBG_INFO, "NVRM: received unknown PM event: 0x%x\n", rqst);
	return 0;

After

default:
	nv_printf(NV_DBG_INFO, "NVRM: received unknown PM event: 0x%x\n", rqst);
	return 0;

Sound

Intel 810 Audio
Supported by kernel OSS driver but the kernel driver (as of 2.4.20) doesn’t support multiple sample rates (causing some audio to play double speed etc.) so use the ALSA 0.9 drivers as they work perfectly.

Infrared Port – IrDA(TM)

I don’t have any IrDA devices so unsure if this works

Floppydrive

USB floppy drive provided and worked beautifully.

Modem

The modem appears to be a Lucent AMR soft modem and I haven’t managed to get it working, so far no drivers found.

Useful Utilities

There are two main utilities that come in handy.
The first and most important is Toshutils available from http://www.buzzard.org.uk/toshiba/
The second contains utils to set the cpu speed/lcd brightness to particular settings (good for getting that last bit of battery life) 5005utils
