RedHat 8.0 Linux on a IBM X30 Laptop

Overall the install went smoothly from a RedHat 8.0 DVD (a novelty, as it was the first time I installed Linux from that medium. It seems not-to-long-ago, that floppy installs were commonplace.)

Everything critical came up first try, namely XFree86 came up, and my eepro100 apapter loaded, etc. Sound even worked. At first the laptop wouldn't suspend, and I originally had though it was a apm issue, so I futzed with stuff in /etc/sysconfig/apmd for a while, but figured out that it would suspend fine from console but not from X. Also, I could not CTRL-ALT-F1, etc to get out to console mode. Well, more specifically, it would go to console but not back, to X without locking the machine. The Intel i830 video card was handled by the i820 XFree86 driver, with some built-in extensions for the i830. I checked out the various XFree86 mailing lists and noticed a lot of work was being done on that chipset, so I pulled a copy out of CVS (2.3.99) and built/compiled it. Also, I updated to the latest stable kernel 2.4.20. See attached XF86Config and .config for specifics. Related info about the driver here (thanks to David Dawes).

Note, all the DRI stuff needs to be working for you to get OpenGL stuff to work as well as the suspend stuff.

The next bit to figure out was the integrated wireless pci card. It uses the prism2 chipset and is supported by the fine folks at AbsoluteValue Systems, Inc.. The syntax, once you've got every thing compile or installed ( I used the rpm's available here for the stock RH8.0 kernels, but had to compile from source when I updated to the 2.4.20 kernel. Anyway, is an example script on how I attach to my Airport network (not *really* and airport but one of those Orinoco access points that *looks* like an Airport, internally). It uses WEP, and that was the tricky bit to figure out the syntax.

#!/bin/bash
/sbin/modprobe prism2_pci
/sbin/modprobe p80211
/sbin/wlanctl-ng wlan0 lnxreq_ifstate ifstate=enable
/sbin/wlanctl-ng wlan0 lnxreq_autojoin ssid=<insert your ssid> authtype=sharedkey
/sbin/wlanctl-ng wlan0 dot11req_mibset mibattribute=dot11WEPDefaultKey0=xx:xx:xx:xx:xx
/sbin/wlanctl-ng wlan0 dot11req_mibset mibattribute=dot11WEPDefaultKeyID=0
/sbin/wlanctl-ng wlan0 dot11req_mibset mibattribute=dot11PrivacyInvoked=true
/sbin/dhclient wlan0

You'll probably want to incorporate this into your /etc/init.d scripts but this gives you the basic gist of things. Also, remember the xx:xx:xx:xx:xx bits of your WEP key is the hexidecimal representation of what would be your Airport "password". For instance, pW3rD would be 70:57:33:72:44. Check `man ascii` for a conversion chart.

I haven't checked the modem, but when I do I'll post it here. Hopefully, it will be a while before I'm unable to find a real network connection. Also, the ohci1394 drivers seem to work but I don't have any firewire stuff to confirm. USB seems to be working nicely on at least mass-storage devices that I've tested, and the X30 included Compact Flash slot also worked out-of-the-box. I think that's about it, if you have questions/comments/corrections, please email me at vmarshall AT fartytowels DOT org .

I actually got all these bits working over the course of the Christmas holidays, and braindumped them on the flight home, so some details might have been obscured in recollection, so please let me know if your experience is different. This is a great laptop and Linux runs beautifully on it. Now if I can only get the Rio s35s I got for Christmas to work with Linux...

I've dumped some (maybe) useful bits of info below:

OS = RedHat 8.0
Laptop Model = IBM X30
CPU = 1.20 Mhz
RAM = 512 MB

RedHat 9.0 Linux on a IBM X30 Laptop

Sometime in May, 2003

Ok, so to update to RedHat 9.0, I already had apt installed from apt.freshrpms.net . So I moved over the stuff from /usr/X11R6 (from cvs) and updated my /etc/apt/sources.list to this:

# Red Hat Linux 9.0
rpm http://ayo.freshrpms.net redhat/9/i386 os updates freshrpms
rpm-src http://ayo.freshrpms.net redhat/9/i386 os updates freshrpms

and did an 'apt-get update; apt-get dist-upgrade', and moved back relevent pieces from the old X tree and all was well.
