You may find useful information on the Linux on Centrino Laptop page at tuxmobil.org.
You may find PCG-Z1A related information on Mark's page. Most of it apply to the Z1SP as well.
My old Vaio PCG N505SN was a bit too old, so I upgraded to a PCG-Z1SP. It comes with:
Of course it is way bigger than the old one, but the better resolution was really appealing. It has Windows XP pre-installed, and comes with 5 rescue CD-ROMs, it may be useful, and they are well done, as they won't erase your linux partition and will reinstall Windows on whatever space you leave for it. I chose to have 20G for Windows and 40G for Linux.

I first tried with with the "testing netinst" CD-ROM. It seemed to work fine until I installed LILO... At that time, it was impossible to boot Linux, nor Windows, I then reinstalled Windows. I then decided to try with the good old Woody CDs. I used Windows to write Ian Eure's woody netinst image and rebooted on the CD.
Here is the partition I used:
Disk /dev/hda: 60.0 GB, 60011642880 bytes 255 heads, 63 sectors/track, 7296 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 * 1 2432 19535008+ 7 HPFS/NTFS /dev/hda2 2433 2556 996030 a0 IBM Thinkpad hibernation /dev/hda3 2557 2680 996030 82 Linux swap /dev/hda4 2681 7296 37078020 83 Linux
If the hibernation partition is not used, it will give me some more swap later. I avoided to add a partition for /var or /home as I will be the only one on this laptop, and then the "safe" setup of regular servers is not needed. (Update, I might transform the hibernation partition into a swap one and use swsusp, more on this later)
The installation went just fine. I installed the base system, LILO (with both Linux and Windows), removed the CD, rebooted, installed woody, then sarge, got kernel sources as well as pcmcia ones, and the machine was (almost) usable.
I compiled a 2.4.22 kernel with the following options:
You can access the complete 2.4 .config
kernel configuration. Use
make oldconfig for more recent
2.4 kernels, like 2.4.24.
The configuration for 2.6 kernels is pretty much the same. I
changed the sound driver to use the alsa one, as it works now (and
it is in the kernel tree). My main issue is that the
sonypi module won't autoload (I have this
alias char-major-10-63 sonypi and
options sonypi minor=63). I need to find time to solve
The framebuffer was not right, I found this patch on the linux-kernel mailing list. Apply it and enjoy a working console and framebuffer!
You can access the complete 2.6 .config
kernel configuration. Use
make oldconfig for more recent
2.6 kernels, like 2.6.4.
It works (of course!) and the 2.4.22 kernel I use allow me to use
throttling (the performance states are not working, I get
acpi_processor-1095  acpi_processor_set_per: Transition failed"
instead of the expected behaviour).
With the processor.o from the kernel sources:
ACPI: AC Adapter [ACAD] (on-line) ACPI: Battery Slot [BAT1] (battery present) ACPI: Lid Switch [LID0] ACPI: Power Button (CM) [PWRB] ACPI: Processor [CPU0] (supports C1 C2, 6 performance states, 8 throttling states) ACPI: Thermal Zone [ATF0] (37 C)
With Intel's processor.o:
ACPI: AC Adapter [ACAD] (on-line) ACPI: Battery Slot [BAT1] (battery present) ACPI: Lid Switch [LID0] ACPI: Power Button (CM) [PWRB] ACPI: Processor [CPU0] (supports C1 C2, 6 performance states (Native), 8 throttling states) ACPI: Thermal Zone [ATF0] (39 C)
The main issue I have is that the computer stay awake after a
shutdown, the screen is powered off, but I have to press a few seconds
on the power button to power down the whole
machine. I modified
/etc/init.d/halt to force the S5 sleep
mode in ACPI, but a fix will be in
2.4.22-pre9, so I
applied the proposed patch and revert
its original version.
Update again. Nils sent me an email pointing me to a
post on linux.kernel.
CONFIG_X86_UP_APIC in the kernel configuration
cause the system to shutdown properly. I suspect that the
ACPI_DISABLE_IRQS(); call in
is just hanging and prevent the kernel to enter sleep state
S5 (power off).
Another note: Depending on the power source, the bogomips value reported at boot vary from 1186.20 on battery to 2968.70 on AC. Is this behaviour caused by the BIOS or the DSDT?
Status: ok (see above)
Works well with the
e100 module. As it works and I don't
use it very often, it's enough.
Intel just released a driver. It is under development, so more functionalities are expected (like Ad-Hoc mode),and it is not mean to be stable.
However, I tried it with kernel 2.6.4 (external build, with "legacy" firmware loading mode) and it works pretty well. Version 0.30 was not working in closed WiFi networks, but 0.34 if ok with that.
I will need to polish some scripts for that, as I manually start dhcp and set some parameters for now.
I still carry my old Orinoco PCMCIA card, just in case something goes wrong (it happened one time with 0.30)
Status: Partially ok
ehci-hcd module, I can access my external disk,
and with the
usb-uhci module, I can see (and use) the
memory stick and bluetooth. See below the output of

It works well also, I was able to use my cellphone as a remote control, using
bluexmms. See the
kernel .config above. Using Debian Sarge (testing), I was
unable to locate the
bluez-utils package, so I downloaded it from
the BlueZ Debian
download page. Useful to debug and test.
It is a yenta socket bridge, so be sure to have

to see if this was solved with no luck. I then decided to patch
the driver myself "the hard way", and it works perfectly now. you

dated 10 Sep 2003, in previous versions, a bug was preventing
external display to work as expected.
Also, I was unable to have direct rendering working. If someone has the solution...
Update: Nils got it right, he gave me his
XF86Config-4, but apparently it will
work only when Debian will move from 220.127.116.11 to 4.3.0...
Also I have to remove
xfstt, as it was preventing me to
start X (endless loop, or extremely time and cpu consuming startup).
You can read my XF86Config-4.
I am currently working (when I can find some spare time) on a tool to
use the function keys. I am using the
sonypi driver to
intercept the events, and
libxosd for the display part.
Here is a binary snapshot that only sets the
brightness. (I wrote the code in ten minutes, it is too ugly to
publish it yet :) ).
Status: almost ok

David reported to me that the sound was cutting sometime,
this behaviour is linked to X activity. It turned out
that the new O(1) schedulers were the cause, so a quick
fix was to fix the nice level of X from -10

Debian installation was quite easy, there are lots of things to
improve to be able to use all the functionalities, like suspend to
disk (it was working perfectly
on my previous
Vaio N505SN, handled by the BIOS),
and screen blanking.
The wireless card got support only in march 2004, better late than
