Introduction

This document describes experiences with running Linux on a Toshiba Portege 4000 Model PP400E-0008L-EN - see also cs.helsinki.fi and it.uc3m.es/ptb.

This page was started a few hours after I got the first machine, and developed as I learnt more. As soon as it was working sufficiently, it was taken back by its user, so I no longer have access to the machine (unless it happens to be on the internet, which is rare).

This report is listed at TuxMobil - Linux on laptops, notebooks, PDAs and mobile phones under Toshiba


Overall Description

The 4000 has a 750MHz Mobile PIII with 32K of L1 and 256KB of L2 cache. It comes with base memory of 128M, and can upgraded to ``1,024GB'' (I assume this means 1GB). It can have a 10, 20 or 30 GBi (9.35, 18.62 or 27.96GB) IBM Travelstar 30GN (4200RPM, 12mS seek, ATA-5). It has a `slim selectbay' which can take a CD, DVD, CD-R/RW, CD-RW/DVD, HDD, or battery.
It has a 12.1" TFT LCD display, managing 1024x768. It has the usual Toshiba AccuPoint II, but as well as the normal 2 buttons, it also has two small `scroll' buttons. There is an SVGA monitor port at the back, next to the modem and ethernet.
It has two typeII Cardbus slots, which can take a single typeIII PCMCIA card, and an SD slot. It has built in Winmodem, and in some countries, WiFi and bluetooth. It has two USB ports, IR port, audio in and out, and a docking station socket. There is an optional USB floppy, but I didn't have one.

Initial system Load

RedHat 7.2 CD Load

The system came with W98 on a single partition using the whole of the disk, although it used less than 1GB. I used PQMagic to reduce it to 4110.4MB.

As I didn't have a floppy, and someone had just burned a RH 7.2 CD, I used that. I did a custom install, partitioned the disk as required, and asked just for Laptop and Network.

Machine capabilities

XFree86 - Trident Cyber BLADE XPm (Napa2) 8820 - use trident or vesa driver

If using the trident driver set `ChipSet "cyberbladeXPm"' and `VideoRam 16384' in XF86Config, and set `vga=791' when booting. Set `Option "Protocol" "IMPS/2"' and `Option "ZAxisMapping" "4 5"' to get the extra buttons to scroll. The keyboard bounces horribly, but using `xkbset bo 1' from math.missouri or `xbounce' from sdb.suse.de seem to help.

APM

`apm -s' saves to RAM (not to disc) `just works'. The battery lasts about 4 to 5.5 hours (see small, medium, large battery graphs).

Setting it to resume mode and pressing the off button or using `apm -s' caused it to hibernate to RAM.

Set `PCMCIARESTART="yes"' to ensure PCMCIA cards restart correctly.

Ethernet - multiple internal interfaces

The machine has a permenantly connected UTP NIC and a (SW) ejectable PCMCIA internal WiFi interface. The order the Linux detects these does not seem (very) deterministic. In is prudent to eject the WiFi card when not using it, so as to ensure that the UTP NIC is eth0, using `cardctl eject'.

UTP Ethernet - Intel 82557 Ethernet Pro 100 - eth0

WiFi - Lucent ORiNOCO - eth1

Use the wvlan_cs (or orinoco_cs) driver.

There is an `on' / `off' switch at the `front', RHS, near the `Portege' sticker to the right of the mouse buttons.

CHECK THAT THE WiFi IS TURNED ON!

PCMCIA/CardBus - TI PCI1410 + Toshiba ToPIC95

It has a single internal slot `Texas Instruments PCI410 PC card Cardbus Controller (rev 01)' to drive the internal WiFi card, and a Toshiba `ToPIC95 PCI to Cardbus Bridge with ZV Support (rev 32)'

Disc - IBM IC25N020ATDA04-0 17MB/s

IBM 20GB Travelstar 30GN 4200RPM, 12mS seek, ATA-5. Without DMA it manages 1.8MB/s; with UDMA2 it manages 17MB/s, UDMA3 it manages 18MB/s.

DVD/CD - TOSHIBA DVD-ROM SD-C2502 - 24x

USB - Acer M5237 - OHCI

`Acer Laboratories Inc. [ALi] M5237 USB (rev 03)'

Audio - ALi M1535/5451 / AK4543

The ALSA snd-card-ali5451 driver works, giving
Card config: ALI 5451 at 0xed00, irq 11
Audio devices: 0: ALI 5451 (DUPLEX)

Memory Stick - Toshiba SD TypA - not tried

Bluetooth - TAIYO-YUDEN - not tried

IrDA - Super IO SMSC LPC47N227 - not tried

WinModem - Softmodem (Agere Systems LU97 - SCORPIO) - not tried

gromitkc says that `LU97 = CSP1037 + CSP1037A/B' and that there is no Linux driver.
