Linux Step By Steps

TOSHIBA 1550

REVISED MARCH 2000
 

I have just loaded Linux onto a Toshiba laptop. 
 

Hardware: 
Toshiba laptop 1550 CDS (very similar to a 2100 CDS)
AMD K6 2 CPU 400MHz
64 MB RAM
24 speed CD ROM
4 GB Hard Disk (1.5 for Linux)
12.1 inch colour dual scan super twist nematic LCD screen
S3 graphics controller
accupoint keyboard mouse
ESS Maestro sound system, drives two built-in speakers
Toshiba LT v90 modem built in
PCMCIA 10/100 network card

Software
Linux Mandrake 7.0 GPL
LT binary module downloaded separately

I spent about an hour slavishly checking the specs of everything under windows prior to attempting to load Linux. I put aside 1.5 GB space on a new partition at the end of the windows partition. I used windows scandisk and defrag, then fips.exe to create the new partition. No data loss was incurred on the windows side in doing this.

A boot floppy was made using the windows rawwritewin.exe program supplied on the mandrake 7 CD, in the dos utils area. It only seemed to work on a newly formatted floppy. Booted from the floppy and followed the install prompts. Made a 128MB swap partition, the rest of the 1.5 GB for a single root partition for Linux. This is to be a single-user
simple installation, no extra partitioning was done.

I chose a custom install, selected about 900 MB of stuff, let it go and followed the prompts. It took about 35 mins to load everything in, then stitch it together. Out of the box all hardware was detected and configured except the LT modem. Automagically sound was set up, the network card was detected (I haven't tested that yet, I don't have a
network to plug into yet) X was set up ok by accepting all the defaults suggested, except I chose 800x600 at 16 bpp for the default resolution.

The lucent technologies LT modem driver version 568 was downloaded from a link from the Linux laptop page, as a zip file, and unzipped and installed using the provided install script. A search for Linux and Laptop on any engine will get you to a nest of inter-linked Linux laptop resources. Read them. A test reboot at this stage showed a problem that stopped the boot at the PCMCIA services line. Since I don't have anything useable on the only PCMCIA card plugged in, I disabled PCMCIA services using the mandrake config tool, re-booted, and I have everything up and running.

Next I spent about an hour removing a whole swag of packages that seemed to come along for the ride. Lots of stuff went west, leaving a total install size of about 500 MB, with a system based around KDE, which I quite like.

The only gripe I have is that X is a bit less than commercial quality in this configuration. Moving or re-sizing a window results in a kind of splattering of ghost images and echoes of hidden icons happening around that window. When the windows are stationary, the reolution is great, crisp, sharp and very nice. I got an XF86config file sent to me by a helpful guy in Finland, but using it did not make any noticable difference. I consider this to be relatively trivial though, it has no
bearing on the usability of the system. If anyone knows of a good fix to this please email me at bmoffatt@picknowl.com.au

*****UPDATE*****
I have modified the XF86Config file in the Toshiba 1550 CDS laptop to get rid of the ghosting and spalttering. I added the line:

Option "noaccel" 

in the Device section of /etc/X11/XF86Config. The display is much cleaner, but a little less smooth when you move a window around.
 

The next thing is to get a good office suite loaded. I will be putting the 4.4.2 trial version of applixware on next week, and will probably be buying version 5.0 when it is released. I have used version 4.3.7 for a couple of years now on my desktop machine, and I could probably not get by without it.

Future plans are to resolve the PCMCIA conflict, and buy another similar laptop - this one belongs to my daughter and she has taken it back. She loves Linux by the way.

I hope this is of some help if only to confirm that all this stuff worked out so easily. Love to hear any comments.

***********Further Update
Here is the final chapter to my Toshiba Laptop story

The PCMCIA problem was found to be a system hang due to interrupt scanning when the i82365.o module was loading. This is a known problem with PCMCIA and is well documented in the PCMCIA-HOWTO.

The fix was simple. In the /etc/sysconfig/pcmcia file add this line:

PCIC_OPTS="do_scan=0"

Reload the PCMCIA modules (or reboot if you don't know how) and that fixes the interrupt scan hang problem.

The ethernet card now works. With help from a mate at work I connected the laptop to a network, set up an IP address (use netcfg) and away it went, just like a bought one.

This now completes the whole exercise. I am happy to take questions on my email address
