| First Impression: | Base system installed without problems. |
| What Works: | XFree.4.2.0 with S3 Savage card auto-detected and installed by Yast2 at 1024x768, mouse/touchpad (peculiarity: the extra navigational button is detected and a 3-button mouse is installed. However, the extra navigational button does not seem to so something. When a 3-button mouse is connected in the PS/2 port, it is automagically detected with the the 3rd button working OK. As an added bonus, the touchpad remains operational). CD, CD/RW, DVD (data, at least SuSE's DVD works OK). UDMA100 on HDD is also recognized. RealTek RTL8139 NIC is recognized and auto configured as 10/100 at boot. |
| What I haven't tested (yet): | USB, FireWire, Parallel port, DVD (movie), PCMCIA |
| What doesn't work (in default install): | Sound, Modem, ACPI, the extra touchpad button |
| What was made to work (so far): |
Sound (date: 02 JUL 2002) HOW-TO Followed instructions found at http://wwwhome.cs.utwente.nl/~berensch/compaq.html, text is also attached below. After installing new compiled kernel, Yast2 could not install sound card through the GUI. So in /etc/init.d/boot.local I added the following line: modprobe via82cxxx_audioSound now works fine! I applied the SoundCompaq.patch (see below for newer versions) against the linux-2.4.18.SuSe tree. ACPI (date: 22 JUL 2002), not 100% but acceptable for me. Read "The ACPI saga" below for more info. |
| The ACPI saga |
The main reason I would like to see ACPI working is to be able to control the
temperature. In the current situation the fan is always on, even when then machine
does nothing for a prolonged period of time, and the keyboard gets getting hotter
and hotter. I'm sure that this can't be good for the health of the machine... What follows is a log of what I did and the pitfalls I run into. If anyone has a better solution, please mail me. Applying the acpi patches from sourceforge.net to the /usr/src/linux tree (which is linked to /usr/src/linux-2.4.18) and recompiling was not possible as the whole process failed at " make modules". On the other hand, applying the same patches to the
/usr/src/linux-2.4.18.SuSE tree failed. Digging into SuSE's sources I found out that
SuSE had already buitl ACPI support with the supplied kernels, although the acpi version
indicated 2001. Booting with "apm=off acpi=on" as kernel params and
afterwards "modprobe -a ospm_ec ospm_system ospm_processor ospm_button ospm_ac_adapter
ospm_battery" produced an acpi tree under /proc. Now,
/proc/acpi/ac_adapter/0/status indicates whether the AC adpater is plugged
or not, but nothing else seems to do something usefull. I have not yet found a way to
stop the fan from running continually. Also, ospm_thermal fails to load. Update : 22 JUL 2002 Temperature problem solved. Added " hdparm -S12 /dev/hda" at
/etc/rc.d/boot.local and now the HDD spins down after approx. 1min.
I've also added the above modprobe afterwards. Now fan actually stops
if the machine sits idle. Also, on halting, it also power-offs.

Linux on the Compaq Presario 700 EASend all comments to Marc Berenschot, E-mail: berensch@cs.utwente.nlIn january 2002 I bought a Compaq Presario 700 EA. It sells with Windows XP pre-installed... Some Specs: Mobile AMD Duron 900 MHz (PowerNow!), VIA Chipset (KN133???), Twister K Graphics, Conexant Modem, 20 GB harddisk, 14.1" TFT, 128 MB Memory (Shared with the Video Card), Realtek Ethernet, pcmcia and USB. Watch out, there is no Serial-Port (I found that out after a few days...). Also the BIOS is not very configurable (read: almost not configurable), even PNP can not be turned off... Since I had the Mandrake 8.1 CDs lying around that became my choice of distribution. Making a base install with these CDs was easy. After installation was complete rebooting the machine was a problem. During boot it rebooted again. And again... Problem was PNPBios. Booting with nobiospnp solved this. Unfortunately I found this out later, after adding another kernel (2.2.19-19mdk). Mandrake installs kernel 2.4.8-26mdk. Because not everything was working
correctly I upgraded to 2.4.17. This solved the nobiospnp problem.
ProblemsThis laptop is 100% ACPI. And Linux is not... So some things are not possible yet (automatic throttling, responding to events, hybernate). Battery Lifetime is short now (I do not turn off disks using hdparm).Update: I have installed kernel 2.4.18 with acpi-20020308-2.4.17.diff. Now batteries and ac-adaptor are recognised and you can see the status. Throttling is still not possible. I did not try sleep and hybernate yet. Another Update: I now have acpi-20020404. But I could not find any differences yet. I now know how to throttle the machine. This might have been possible with the previous patch, but I did not know how to do it. I have not yet used the laptop for a longer time with this patch, so I don't know what it does with the battery-life. I hope it is better now. Events are still not detected UPDATE (26 April): I found a patch on the ACPI mailing-list for the presario 711 FR that should make events working. I tried it and it does! So now it is possible to use acpid. And hopefully the machine will use less power since it is spending more time in the C2 state. The patch is from Juliusz Chroboczek and you can download it on the bottom of this page. His page is here. Currently I am running the 20020503 acpi-patch with the kacpid.patch. It is working very well now. Battery lifetime looks better and it doesn't feel as hot as before. The fan is off now for most of the time (used to be running at full speed). Since it is a FAQ here is how to apply a patch:
No ProblemsThe soundcard has been a problem for a long time. David Gardner sent me a patch from Santiago Nullo for kernel 2.4.18 and now it works!The Network Card is a Realtek RTL8193. It was running immediately after install, no problems encountered with it. The modem is offcourse a winmodem (Conexant HSF). But with the driver from http://www.mbsi.ca/hsflinux (hsflinmodem-4.06.06.02mbsibeta02022600) I could get it to work. So thanks to Marc Boucher. Framebuffer device is working properly. So X is running, but without any acceleration. I have to check which version of X I am using. It is possible that XFree 4 is already supporting this card. Update: And that is true, so now it is running accelerated on Xfree 4 and there is no problem with the graphics. It looks like the PCMCIA adapter is running. Inserting cards is detected. I did not install any PCMCIA card since I don't have them. USB is recognised and modules are inserted. I have tried an Intellimouse and it works. Even the Scroll-wheel works without a problem. Touchpad is working fine. It also has an extra button with functionality comparable to a scrollwheel. The extra button does not work and I am not yet trying to get is to work since I don't use it anyway. Same thing for the send-e-mail-key and friends. CD-Rom player and diskdrive work correctly. Also the Harddisk works fine and it uses UDMA-100. Files and linksSound patch: SoundCompaq.patchKernel Config file: config.2.4.18 Acpi event patch:kacpid.patch The acpi patches can be found at sourceforge The Linux Kernel HOWTO (It is a question I very often get and it is taking to much time to answer): http://www.tldp.org/HOWTO/Kernel-HOWTO.html ConclusionAt this moment this laptop is not the Ultimate Linux Laptop. But I think this goes for all ACPI laptops. The biggest problem in my opinion is the short battery life (I think aprox. 1.5 hours). But progress with ACPI is very good, they are currently releasing patches very quick. So hopfully in a few months... |
