작은 재미 찾아가기

It's the installation guide for HP 6715b notebook users. This laptop is something special one which has not accepted to install Linux easily. So I wrote this log for someone who want to install Linux.

In my case, 6715b has MK-38 Turion single core processor. Stepping no. is 2, 2.2 GHz frequency. I also paste /proc/cpuinfo contents below.

As you could see, CPU's flags has pni. This flag is meaning "This Processor has SSSE3 Instruction Set." Yes. It has. But that was not stable for temporature aspects. Don't worry. After free radeon driver support X1250 natively, ACPI also has affected power management for CPU. You could use SSSE3 instruction stably and slowly.

I upgraded my computer specs in memory and hard disk. 6715b has two memory bank slots, bottom of machine and below keyboard. Two DDR2 PC5300U 2 GB Memories and WD Blue 2.5" 500 GB 5400 RPM HDD with 8 MB cache. (I recommend to use some HDD with 16 MB cache. 8 MB is not enough to use laughly.)

The most problem to install Linux on 6715b is 'ACPI'. It has trouble on booting process. ATI's video core rejected to be managed by linux distribution kernel's acpi module. If you want to install Linux without compile, I recommend to install OpenSUSE 11.1 with safe settings mode. That is able to install Linux for 14 hours. After installation, maybe you has doubt about your notebook's performance. It could be felt slower than using MS Windows Vista(C).

So you need to install Gentoo Linux on 6715b. It's more faster, good fancy, more utilized, and no-limitation of your computer's. Yes. It's really free!

After booting with Gentoo Linux minimal install CD or LiveUSB, etc. (Anything you could use live CDs without graphic interfaces.), if you meet the gentoo linux kernel compile interface, you must check follow modes. These modes are support for turion's and your laptop I/O's. Ah! Before compile anything, you must check your gcc's CFLAGS. In my case, I set CFLAGS="-O2 -pipe -march=k8 -msse3". Of course CXXFLAGS too.

General Setup ->
  [ ] remove sysfs features which may confuse old userspace tools (Don't set, It's for udev.)
Processor type and features ->
  [*] Symmetric multi-processing support
  [ ] GART IOMMU support (Don't set)
  [*] AMD IOMMU support
BUS Options (PCI etc.) ->
  [*] Interrupts on hypertransport devices
Networking Support ->
  <*>   Bluetooth subsystem support ->
    <*> Bluetooth device drivers ->
      <*> HCI USB driver
      <*> HCI BCM203x USB driver
  <*> Wireless ->
    <*> Improved wireless configuration API
Device Drivers ->
  <*> SCSI device support
    [*] Probe all LUNs on each SCSI device (for internal Flash memory reader)
  <*> Serial ATA (prod) and Parallel ATA (experimental) drivers ->
    [*] ATA ACPI Support
    [*] SATA Port Multiplier support
    <*> AHCI SATA Support
    <*> ATA SFF Support
      <*> ATI PATA support

Kernel Setting File

It's too much! I just attached my kernle's configuration file '.config'. You must check each settings. Cause I check most of TCP/IP rules and extension drivers for extended services. Important points are GART, radeon DRM, ALSA intel HD Driver (You must set ADI driver. It's not ATI IXP drivers!), X86 Platform Specific Device Drivers -&gt; WMI and HP WMI, I2O, I2C, Monitoring device STMicroeletronics LIS3LV02Dx three-axis digital accelerometer.

In fact Kernel 2.6.31 has perfect supports for 6715b. From video card driver to fingerprint scanner, you could use with your detailed settings.

Anyway, after compile kernel, don't forgot to emerge 'b43-fwcutter' and download firmware file from linuxwireless.org for wireless lan. *.fw files is needed on /lib/firmware/b43 directory.

After booting with your custom compiled kernel, you need to install X and KDE environment.

I also paste my emerge-info contents.

For using avahi, you must set howl-compat and mdnsresponder-compat USE flags.
'djvu', free pdf encoder and decoder, is using qt3 library. So I don't recommend to use djvu for KDE 4, instead of using poppler. But ebuils has bugs for poppler-utils-0.12.1. To avoid compile error, you must set package.mask on /etc/portage directory.

=sys-devel/binutils-2.20
=app-text/poppler-utils-0.12.1
=dev-libs/poppler-0.12.1

And some packages has troubled to compile on one time. It's from the USE flags set. It's also need to be set on package.use files.

net-dns/avahi -gtk -qt4
media-libs/urt -gif
www-plugins/adobe-flash -32bit

...

Yes. That's all. (But not completely.) If I have the time, I also want  to explain rule of kernel drivers and libraries. But It couldn't. Anyway, I want this article to be good hints for using Gentoo Linux on HP 6715b.
