Linux on a Toshiba Satellite 2430-301

By Jochen Voss, last updated 2012-02-18

This text describes the adventures I encountered while installing Linux on a Toshiba Satellite 2430-301 Laptop. If you have questions or additional hints, feel free to contact me.

News. in February 2005, less than two years after I bought it, the laptop described on this page died. The symptoms were:

The fans seemed to start to produce a little bit more noise than they used to do.
The machine switched itself of from time to time, seemingly from overheating (at least it was quite hot). This effect got worse and worse over the time until the machine was mostly unusable.
One day it did not recognise it anymore when the power cord was plugged in. After the battery was emptied, the machine was of course no longer very useful.

This might be the problem discussed at the computer hardware forum.

Summary

I was able to install Debian GNU/Linux without an unreasonable amount of trouble.

component	hardware identification	status
core components	Intel Pentium 4 (2.66 GHz) 512 MB RAM IDE hard disk	works perfectly
graphics card	NVidia GeForce4 420 Go (rev 163) 32 MB	works perfectly (using the closed-source NVidia driver)
sound	Intel 8x0	works perfectly (I use the ALSA driver)
Ethernet Controller	RealTeX TRL8139 Fast Ethernet	works perfectly
USB	Intel 82801DB USB EHCI	works perfectly (using the usb-uhci driver), USB 2.0 never tried
Power Management	APM or ACPI	works partially: Power off works, but suspend does not
Modem	unknown (to me) chipset	works (using the proprietary SmartLink driver)
PCMCIA slots		works perfectly
SD card slot		never tried
Infrared port		never tried

Table 1. This table summarises the hardware support for the Toshiba Satellite 2430-301 under Linux.

BIOS

The pre-installed BIOS version is 1.30. The boot message says

PhoenixBIOS 4.0 Release 6.0

I upgraded to BIOS version 1.60 in the hope that this would involve an ACPI BIOS upgrade. It did not: The new BIOS is for me almost indistinguishable to the old one. The corresponding part of the dmidecode output is

Linux Kernel

Kernel Version 2.6

Linux kernel 2.6 works fine. Currently I am running the Debian flavour of kernel 2.6.5. Some information about my setup:

the kernel config file config-2.6.5.
the kernel's boot messages as obtained by dmesg.
the lspci output
the dmidecode output

Kernel Version 2.4

I successfully tried the Linux kernel versions 2.4.20 and 2.4.21.

Warning: I had to disable the Local APIC support on uniprocessors feature in the kernel configuration. With the local APIC enabled the machine hung immediately after LILO passed control to the kernel.

The following link points to my kernel config file: config-2.4.21

Modem

The built-in modem works fine under the Linux kernel 2.6.7 with the proprietary SmartLink driver slmodem-2.9.10 from SmartLink's linux driver page.

I do not know which chipset the modem uses, but the following information is available:

The Toshiba product web page for the machine states that the modem is a Scorpio AC 97 soft modem produced by Agere.

The modem shows up in the lspci listing:

00:1f.6 Modem: Intel Corp. 82801DB AC'97 Modem (rev 02) (prog-if 00 [Generic])
	Subsystem: Toshiba America Info Systems: Unknown device 0001

		Status: D0 PME-Enable- DSel=0 DScale=0 PME-

The SmartLink driver produces the following messages while loading the kernel module:

slamr: SmartLink AMRMO modem.
slamr: probe 8086:24c6 ICH4 card...
slamr: mc97 codec is SIL27
slamr: slamr0 is ICH4 card.

Under Windows XP the Modem identifies itself as follows:

ATI3 TOSHIBA V.90 Data+Fax Software Modem Version 3.1.116
ATI4 Built on 09/17/2002 16:12:37
ATI5 3.1.116, AMR Intel MB, AC97 ID:SIL REV:0x27, 06

Infrared Port

Windows identifies the infrared port as an SMC IrCC - Fast Infrared Port.

ACPI

The ACPI BIOS has a lot of problems. In short: powering the machine down works, but nothing else.

The file /proc/acpi/ac_adapter/0/status correctly shows whether the machine runs on AC power. But the battery status information at /proc/acpi/battery/0/status seems to always read

Present:                 yes
State:                   ok
Present Rate:            0 mA
Remaining Capacity:      2040 mAh
Battery Voltage:         14800 mV

Under linux 2.4.21 you can only read out these vales two times in a row. Starting with the third time the error message

Present:                 yes
Error reading battery status (_BST)

is displayed and the systemlog shows things like

ectransx-0199 [-3] ec_read               : Unable to send 'read command' to EC.
evregion-0302 [-6] Ev_address_space_dispa: Region handler: AE_TIME [Embedded_control]
 dswexec-0392 [-15] Ds_exec_end_op        : [Store]: Could not resolve operands, AE_TIME
Ps_execute: method failed - \_SB_.PCI0.LPC0.BAT1._BST (c15ae828)

then. I did not investigate wheter this is a kernel bug or an ACPI BIOS bug.

Reading the CPU temperature etc. does not work.

I tried to override my ACPI BIOS with a fixed version, as described in Intel's Overriding your BIOS's DSDT page. Recompiling the disassembled ACPI code uncovers some syntactic bugs (missing return values etc.), but fixing these does not visibly improve things.

The Omnibook Module

Using the Omnibook kernel patch makes several things work better. Despite of its name, the project actually intends to provide kernel support for several classes of notebooks, including Toshiba Satellite ones.

While installing the module I get the following promising kernel messages:

omnibook: module version 2004-01-20.
omnibook: Toshiba Satellite 2430 detected.
omnibook: AC adapter status monitoring is enabled.
omnibook: Battery status monitoring is enabled.
omnibook: LCD display turn off at console blanking enabled.
omnibook: External display status monitoring is enabled.
omnibook: Fan status monitor and control is enabled.
omnibook: Fan policy setting is enabled.
omnibook: LCD brightness handling is enabled.
omnibook: OneTouch buttons are enabled.
omnibook: Temperature monitoring is enabled.
omnibook: module unloading does not work yet on 2.6 kernel.
atkbd.c: Unknown key pressed (translated set 2, code 0xb4 on isa0060/serio0).
atkbd.c: Use 'setkeycodes e034 <keycode>' to make it known.
atkbd.c: Unknown key released (translated set 2, code 0xb4 on isa0060/serio0).
atkbd.c: Use 'setkeycodes e034 <keycode>' to make it known.

Using this patch, the one-touch keys (right of the power button) and CD player controls (at the left hand side of the machine's front edge) actually produce scan codes and can be used with tools like ACME. Also I can read out the processor temperature and current battery status from the files in /proc/omnibook/.

Miscellaneous

There are some minor things which do not work:

The Intel chipset is supposed to contain a hardware random numer generator. This device does not work. The corresponding kernel message is
```
hw_random: cannot enable RNG, aborting
```
The Fn key acts a little bit strange. Pressed alone it does not generate any scan code. The keys Fn-F6 and Fn-F7 to control the brightness of the display work fine. But pressing Fn-F7 gives the following kernel messages every time:
```
atkbd.c: Unknown key pressed (translated set 2, code 0x10f, data 0x59, on isa0060/serio0).
atkbd.c: Unknown key released (translated set 2, code 0x10f, data 0xd9, on isa0060/serio0).
```
Fn-F6 gives no such messages. Fn-F9 to toggle the mouse works fine. Fn-ESC emits the scan code for the F13 function key.
The mouse daemon gpm dies sometimes without appearent reason. The corresponding message from the syslog is
```
/usr/sbin/gpm[971]: oops() invoked from gpn.c(205)
```
