Important note
Be aware that it does not have an integrated serial
port !! (I found that out after I had bought it...)
(you will need to use a USB protocol converter if you want to
use any serial peripherals).
Core system
There is a bug in the PCI chipset which
causes the machine to lock when using a kernel optimised for Athlon/Duron.
A workaround is included in kernel 2.4.18 and probably in later kernels.
This workaround is enabled if you see the following line in your kernel
log:
Disabling VIA memory write queue: [55] 3c->1c
For some reason, the system hangs on
boot if you enable the local APIC.
Use kernel 2.4.18 and choose "Athlon/Duron/K7 processor family";
disable "Use local APIC on single
processors".
Here is my .config for kernel 2.4.18
and the .config for the 2.5.x development
serie.
There aren't any problem with IRQ routing
neither with vanilla 2.4.x kernel nor with any of the ACPI patches.

Power management
The Presario 705 does not have an APM
compatible BIOS. Unless you use ACPI, the fun will run all the time and
the machine will run very hot. I can report success with version 20020404
of the ACPI code available from the ACPI project's
site.
With this patch, all ACPI functionality works with the exception of suspend
and performance management. (Both S3 and S4 suspend states cause a hang
on wakeup; according to Pavel Machek, the problem is understood and being
worked on. The Presario's BIOS doesn't advertise support for S1.)
(The Presario does performance management using AMD's PowerStep interface
and the support for this is in development in the 2.5.x series.)
Apply acpi-2002xxxx-2.4.xx.diff with date >= 2000918 or a previous version but with this kacpid.patch applied, then enable all ACPI options.

Software suspend
The swsusp patch appears to work with the Presario, and
partly compensates for the lack of ACPI suspend.
Swsusp can't disable automatically the eth interface, so you have the disable
and enable it manually before and after software suspend.
I use this suspend script.
If you want to try swsusp apply patch-acpi-acpi2002xxxx-swsuspx and select "Software suspend" in the kernel config.
Dual Boot with Windows XP
I've deleted the system rescue partition
that comes with the presario out of the box, resized the NTFS partition
with Partition Magic 7.0 and installed linux in the second partition. So
I have windows on /hda1, linux on /had2 and swap partition on /hda3
If you want to enable the dual boot, here is an example of lilo.conf:
prompt

vga=791

PCMCIA
No problem with it. I''ve tested a Cisco
Aironet 353, and it works well. The only issue is that there is only one
slot for PCMCIA cards. I cannot insert the arionet and the GPS module at
the same time...
Choose "Support for hot-pluggable devices", "PCMCIA/CardBus
support" and "CardBus support".
Network
Works fine with the 8139too driver. Choose "RealTek RTL-8139 PCI Fast Ethernet Adapter support".

Add to the /etc/modules.conf the following
line:
alias eth0 8139too
Sound
The sound chipset is an AD1886 and is supported
by the ac97_codec.
Version 0.9.0rc5 of the ALSA drivers supports this machine out of the box. Simply
configure them with
./configure --with-cards=via82xx
then edit the /etc/modules.conf and add:
alias char-major-116 snd
options snd cards_limit=1
alias char-major-14 soundcore
alias snd-card-0 snd-via82xx
alias sound-slot-0 snd-card-0
alias sound-slot-1 snd-card-0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-1-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-2 snd-seq-midi
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
If you want to try the development kernel
2.5.x, the ALSA driver are integrated in the kernel tree.
Chose "Sequencer support", all the bool state of "OSS api emulation"
and unter PCI devices "VIA 82C686A/B South Bridge"
USB
USB works correctly and it detects my Logitec
optical mouse. Choose "UHCI support".
Add in your /etc/modules.conf
alias usb-controller usb-uhci
CD-Writer
You need to enable the SCSI-emulation in the kernel and
to pass the "hdc=ide-scsi" directive to the kernel at bootstrap.
To do so edit your lilo.conf and add:
append="hdc=ide-scsi"
Touchpad
It is a Synaptics PS/2 TouchPad. Choose "PS/2 mouse".
Modem
The Conexant HSF modem is a cheap controllerless
and DSP-less thing; however, the CPU is fast enough to make it work
with no noticeable decrease in interactivity.
It is supported under Linux using proprietary (binary-only) drivers
available from Marc
Boucher's site.
FrameBuffer
Framebuffer is working correctly.
You have to select the support for the "VESA VGA graphics console"
because the S3 Savage doesn't have specific support.
To enable the graphical penguin at bootstrap you have to pass the vga=xxx
to the kernel (edit the lilo.conf to do so).
The supported value for the vga parameter are:
resolution vga value
-----------------------
800x600 771
1024x768 791
look at /usr/src/linux/Documentation/fb/vesafb.txt for more
values.
XFree86
The video chipset is a S3 Savage Twister
K. While this chipset is supported by XFree86 since version 4.1.0,
it is not (yet) detected automatically. Manually configuring XFree86
for any Savage chip should give you a working XF86Config. Make sure that
the Device section of your XF86Config looks as follows:
Section "Device"
Identifier "S3 Savage Twister
K" # identifier doesn't care
Driver "savage"
BoardName "Unknown"
Option "VideoRAM" "16384"
# Option "no_accel"
# You may enable this if there are timeouts when starting X
# Option "xaa_benchmark"
EndSection
To get both touch pad and USB mouse work
under X take a look at this section:
Section "ServerLayout"
Identifier "XFree86 Configured"
Screen 0
"Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Mouse1" "Alwayscore"
InputDevice "Keyboard0"
