Installing Slackware/11.0 on a ThinkPad T42

As the name suggests, this page documents a start-to-finish installation of Slackware 11 on a thinkpad T42. This is a work-in-progress, so check the history page for mistakes I made (if you are that type). Original installation done by User:Frobnitzem, additional edits performed by:

System Information

Gathering system information is like mice storing away for winter.

CPU	Pentium M, 1.7 GHz
Monitor resolution	1400x1050
Graphics	ATI Mobility Radeon 9600
Network	Intel Pro/1000 MT Mobile Connection
	Intel Pro/Wireless 2200BG
CD/DVD	Matshita DVD-RAM UJ-812
PCMCIA	TI PCI-4520 Cardbus Controller
Sound	AD1981B(AC'97) (module snd-intel8x0 works on 2.4 kernel)
IR	IBM ThinkPad FastIR
HDD	Intel 82801DBM UATA-24CA for Fujitsu MHT2080AH

These sections follow in the order I installed them, with some of the later customizations do-able while the kernel is recompiling.

Installation proper

Grabbed a DVD install of Slackware 11 [1]. It failed to boot (maybe 2.4.33 kernel shipped doesn't recognize the drive?). Grabbed install CDs ibid. Sat through package selection process. Created a second user account (useradd).

Found out that sound is muted by default. Fix:

1. amixer set Master 70 unmute
2. amixer set PCM 70 unmute
3. amixer set CD 70 unmute
4. alsactl store

Installed all my favorite software, not worrying about how to make the wifi work for now or optimizing video performance.

Updating the Kernel to 2.6.x

As you may know, the wifi driver is in the 2.6.4 or newer kernels. This necessitated more work on my part and while I was at it I may as well recompile some respectability into my kernel.

1. cd install-media/extras/linux-2.6.17.13
2. pkgtool
   1. no to kernel itself (patience grasshopper)
   2. yes to source (modules and/or headers optional)
3. cd /usr/src/linux yes, the symlink had been changed to 2.6
4. install suspend2 kernel patch
   1. bzcat /path-to/suspend-2.2.8.2-for-2.6.17.13.patch.bz2 | patch -p1
5. cp .config Default.config
6. make mrproper
7. make menuconfig
   1. See options section, below.
   2. strangely, make complained about --no-stack-protector, so I deleted that option
8. If you aren't using any other frame-buffer, make sure to add radeonfb to /etc/rc.d/rc.modules.

Suspend2 Kernel Patch

The last kernel patch for 2.6.17.13 released is 2.2.8.2-for-2.6.17.13 [2]. This requires the suspend2-userui version 0.6.4 [3]. I used the latest hibernate script, since this did not have any version disclaimers...

Kernel Options

Make sure you save your config. options somewhere safe, since you will probably need to recompile and/or reinstall the kernel sources a couple of times to get all the options right. In order to avoid compile-time errors, use make mrproper before make modules, but note that make mrproper deletes .config.

• Processor Family = Pentium M (scroll down)
• ACPI Options
  • CPUFreq driver = Intel Enhanced SpeedStep
    • ACPI Processor P-States = fall-back module
• IrDA
• Added reiserfs into the kernel to avoid messing with initrd
• Disabled all graphics modules in Devices->Graphics support except ATI Radeon display, which I built as a module (so as not to interfere with ATI's driver later)

1. 1. If you do this, make sure to add radeonfb to /etc/rc.d/rc.modules, since my system didn't load this module automatically and I had to login and modprobe it blind.

Recompile kernel overnight.

(make && make modules) ||  echo "poo-bear"

Install the thing. make modules_install depmod -ae 2.6.17.13 # I have heard that this is a good think to do, but your mileage may vary. make_install

realize that slackware is still using lilo, so install has just replaced vmlinuz. Copy original to unique name and symlink, then install new lilo menu.

cd /boot
cp /usr/src/linux/arch/i386/boot/bzImage vmlinuz-2.6.17.13-Farfrumlernen
rm vmlinuz
ln vmlinuz-2.6.17.13-Farfrumlernen vmlinuz
vi /etc/lilo.conf 
lilo
reboot # with fingers crossed

Make sure you add another image="vmlinuz.old" to the file just incase the worst should happen... And hey, why not add append = "acpi_sleep=s3_bios" from SUSE on T42 while you're at it! My system hung on bootup with my first try here because it couldn't mount some filesystems. I added the noauto option to appropriate drives in /etc/fstab and everything was peachy again.

WiFi

Follow the install from source options, and don't forget to patch ipw2200-2.tgz because you're going to compile it anyway. I mistakenly used the development version of ieee802011-1.2.17 (instead of 1.2.15) with ipw220-1.2.0 and ipw2200-fw-3.0, but it is working anyway.

1. ieee802011-1.2.15
2. ipw220-1.2.0
3. ipw2200-fw-3.0 (contents of folder ipw2200-fw-3.0 not the folder itself goes in /lib/firmware)

In order to test wifi and make the thing go once it is working, I installed the Wireless Assistant package.

Some Customization

Added suggested sections to /etc/modules.conf and /etc/modprobe.conf from Ipw2200, IrDA, and others.

/etc/modprobe.conf -- supercedes modules.conf with 2.6.x kernels

alias irda0 nsc-ircc
options nsc-ircc dongle_id=0x09 io=0x2f8 irq=3 dma=3
options ipw2200 led=1
options ipw2200 disable=1

Followed instructions on How to configure acpid to create scripts in /etc/acpi.

Muse at all the time I could spend on making special keys work.

X11 Configuration

Installed ATI's own Mobility Radeon driver installer [4].

Additions:

• Option "DPMS" in Monitor section.
