3.2. HP hardware supported by Linux

The latest version of XFree86 is the 3.3.6, available from our mirror.

To use the MGA G100 AGP card, with a version of XFree86 before the 3.3.2 one, you have to use an option in the file XF86Config : Option "no_accel".

Section example :

Section "Device" [...] VendorName "Matrox" VideoRam 4096 Option "no_accel" EndSection

The maximum resolution supported by vthis chipset in frame-buffer mode is 800x600 in 16 bpp (vga=0x315 in /etc/lilo.conf)

This chipset is also supported by XFree 3.3.6 with the Mach64 driver and a patch available at http://www.staikos.on.ca/~staikos/tp1460/XFMa64-Rage-Thinkpad.patch.

A precompiled X server is available at this address : http://www.0wned.org/XFMa64-Rage-Thinkpad.tar.gz.

To use a Cirrus Logic GD 5465 AGP card, with a version below Xfree86 3.3.3, you have to use an option in the file XF86Config : Option "xaa_no_color_exp".

Section example :

Section "Device" [...] Identifier "CL-GD5465" VendorName "Cirrus" BoardName "GD5465" VideoRam 2048 Option "xaa_no_color_exp" EndSection

Some users who had problems with the support of this chipset were more satisfied with the use of the "sw_cursor" option.

Specifications of that card should be consulted on Elsa web site. This card is equiped with an hardware OpenGL accelerator. Under Linux, there is an OpenGL compatible layer called Mesa. This layer begins to support hardware accelerators, and among them the 3DLabs chipset which is on Elsa Gloria cards.

• OpenGL web site

• Mesa web site

This card is only supported from the 3.3.6 version of XFree86. Nevertheless, even in that version, this is a preliminary support, which isn't as stable as the Frame Buffer mode.

On the other hand, to be able to install a RedHat 6.1 version, you should do that in text mode, because the server provided (3.3.5) doesn't support this card.

If you have a dual-boot system, booting first on Windows, and initialize the card through its driver seems to improve the oprations then under Linux (warm reboot).

Versions of XFree86 above 4.0.2 also offer the support of this chipset.

These cards are only supported with a specific X server XFCom_i810/5 downloadable in both format RPM or tar.gz and a complementary module for the kernel agpgart, downloadable in both format SRPM or tar.gz (old).

Detailed documentations on the installation are provided at http://www.linux-france.org/article/x/GuideIntel810/book1.html and ftp://download.intel.com/support/graphics/intel815/release_linux.pdf

To summarize, once the X server installed, the module compiled and installed, it's sufficient to modify with the following parameters the file /etc/X11/XF86Config :

Section "Device" [...] Identifier "i810" [...] EndSection [...] Section "Screen" [...] Driver "svga" Device "i810" [...] EndSection

You have to note that the agpgart module provided by Intel should replace the one delivered in the kernel so that it works. You then have to reinstall it, particularly when a kernel update occurs.

This card is only supported with a specific X server downloadable at ftp://ftp.s3.com/pub/s3/desktop/395/395_xf86_1011.tar.gz

For the installation, please read the following document

To use the Frame Buffer mode, please consult the following documents http://www.medasys-digital-systems.fr/linux/framebuffer.html and http://www.medasys-digital-systems.fr/mirror/linux/LDP/HOWTO/Framebuffer-HOWTO.html.

The latest version of the aic7xxx driver is available from the reference site.

The latest version of the ncr53c8xx driver is available from the reference site.

A driver disk for the RedHat distribution is available at the following address for the versions 6.2 and 7.0.

To use the D6692A card, you need to use a 2.1.122 kernel at least. Previous kernels didn't handled correctly the shared IRQ between the network and SCSI parts of the card. In particular, a standard RedHat 5.2 version doesn't allow to the network part to be supported. You have to update your kernel with a recent one (preferably 2.4.3) and the distribution with the complementary packages needed.

The latest version of the 3c59x driver is available from the reference site.

There is also a version provided and supported by 3Com, available at http://support.3com.com/infodeli/tools/nic/linuxdownload.htm.

There are also other drivers available at ftp://ftp.scyld.com/pub/network/test/3c59x.c and http://www.uow.edu.au/~andrewm/linux/#3c59x-bc.

This card is supported by kernel 2.2.17 and upper.

The chipset 2EM (Vendor id: 125d - device id: 1978) is supported in 2.2.14 kernel and upper. Version 3 (Vendor id: 125d - device id: 1998) on the other side is supported in 2.2.19pre5 kernel and upper. Cf : the site of the maestro3, driver, in the Alsa^Rem. project (version >= 0.5.10) driver, and in the commercial software Open Sound System . The latest version of the ESS Maestro driver is available from the reference site.

The latest version of the AD1816 driver is available from the reference site.

For Visualize workstations, it's recommended by HP to put in /etc/conf.modules :

alias sound ad1816 pre-install sound /sbin/insmod sound dmabuf=1 options ad1816 io=0x500 irq=5 dma=0 dma2=3 ad1816_clockfreq=33000 alias midi opl3 options opl3 io=0x388

The Alsa project has for primary goals to develop drivers to support sound cards in Linux, being fully compatible with current OSS drivers, bringing more functionalities and supporting more hardware.

All the information on this project, as well as sources under the GPL license, are available from their home page http://www.alsa-project.org

RPMs for RedHat 6.2 and Turbo Linux 6.0 distribution are available at the address http://hp-linux.org/aau/alsa

These models are delivered with MS-DOS only, in order to have a Linux Machine at the best price.

These models are delivered ready to be installed with Turbo Linux, in order to have a Linux Machine at the best price (2 CDs + 30 days of support).

On that machine, the Bios doesn't give the right amount of memory which is in the machine to Linux. You need to use a line such as append="mem=xxxM" at the begining of /etc/lilo.conf where xxx is your RAM in MB.

The support of "big size" IDE disks (for example, 27 GB disks provided for the XU 800) on these machines needs a kernel 2.2.15 at least.

If you intend to use both the sound chipset and a PCMCIA card in this laptop, in order to avoid conflicts at input/output ports level, you'll have to modify the file /etc/pcmcia/config.opts to change the line 6 to

include port 0x300-0x4ff, port 0x1000-0x17ff

The NSC PC87108/338 chipset controlling IrDA on this model is supported by the 0.93 kernel. (Source : http://www.bits.bris.ac.uk/madmatt/laptop.shtml)

Some users had to apply the same tric for their Omnibook 4150 with success.

It is recommended to not launch /sbin/halt under X11. The integrated modem card is not supported under Linux (ESS ES56CVM-PL).

The installation of a RedHat 6.2 distribution gives a problem when rebooting the system, at the PCMCIA initialisation. You have to install the latest version of the pcmcia-cs package at ftp://pcmcia-cs.sourceforge.net/pub/pcmcia-cs/

To use the network, you need a tulip driver modified by P. "goldpenguin" Depouilly, and available at http://www.math.u-bordeaux.fr/~depouill/XE3/tulip.tar.gz

These models are delivered preloaded with a improved distribution based on RedHat (shameless plug, as I did it :-)

In order to use the native SCSI controler you need to disable in the Bios the option "Reserve PCI Bus Numbers", in the menu PCI Device Setting. (Indication of GILLYNN COUCH)

To use the native SCSI bus of this machine, it's necessary to use the sym53c8xx driver with a version upon 1.6c. A driver disk for RedHat distributions is available for versions 6.2 and 7.0.

For the SuSE 7.0 distribution, you have to enter the manual mode to load the driver, as autodetection doesn't work correctly.

In order to use the native SCSI controler you need to desactivate in the Bios the "reserver PCI Bus #s", in the menu PCI Device Setting. The PS/2 system doesn't work correctly with a RedHat 6.1 or 6.2 distribution. In order to correct that you need to either put the machine in MPS 1.1, in the BIOS, or use a kernel above 2.3.47 in MPS 1.4 mode. The network card doesn't work correctly with the kernel of the RedHat 6.2 distribution.

In order to use the native SCSI controler you need to desactivate in the Bios the "reserver PCI Bus #s", in the menu PCI Device Setting.

Intel BX Chipset (Memory Bus at 100 MHz) is supported by kernels above 2.0.34/2.1.103.

Coppermine 0.18 µm technology - 256 kB synchronous cache - Intel i820 Chipset

These machines are equiped with a Pentium IV processor, supported by kernels 2.2.18/2.4.0 and above. The RedHat 7.0 and TurboLinux 6.1 distributions, e.g., can be installed correctly on this kind of machines.

Attention, the XF86_SVGA server works correctly with this mother board embedded version only above XFree86 3.3.5, due to the use of different frequencies (In particular, use the updates for RedHat 5.2/6.0).

Creation of a custom RedHat 5.1 Boot disk

To be able to boot with the RedHat 5.1 boot disk, and to have the support of the 3C905B-TX card, you need to do the following :

# Log as root. Go in the home directory (~root) #cd ~ # Put there the 3c59x.c source module for the 3Com card #ncftp ftp://ftp.medasys-digital-systems.fr/pub/linux/networking/drivers/3c59x.c # Compile it #gcc -DMODULE -D__KERNEL__ -Wall -Wstrict-prototypes -O6 -c 3c59x.c `[ -f /usr/include/linux/modversions.h ] && echo -DMODVERSIONS` # put the RedHat 5.1 floppy boot disk in the drive # you have to copy the initrd.img file from the floppy disk #mcopy a:initrd.img /tmp # then uncompress it #gzip -cd /tmp/initrd.img > /tmp/initrd.ext2 # Mount the "file" filesystem thus obtained #mount -t ext2 /tmp/initrd.ext2 /mnt/floppy -o loop # uncompress the modules provided #gzip -cd /mnt/floppy/modules/modules.cgz > /tmp/modules.cpio # extract the modules #cd /tmp ; mkdir modules ; cd modules ; cat /tmp/modules.cpio | cpio -i # Copy the new updated module for the 3Com card #cp ~/3c59x.o . # recreate the compressed cpio file #ls | cpio -o | gzip -c9 > ../newmodules.cgz # replace the modules by their update #cp ../newmodules.cgz /mnt/floppy/modules/modules.cgz # unmount the "file" filesystem #umount /mnt/floppy # compress the "file" filesystem #gzip -c9 /tmp/initrd.ext2 > /tmp/initrd.img # copy it on the floppy disk #mcopy /tmp/initrd.img a:

To be able to boot with a RedHat distribution (>6.1), and to have the recognition of a peripheral non supported in standard in the distribution, you need to do the following :

Download the delopment toolkit to create driver disk for the RedHat distribution at the following address: http://people.redhat.com/dledford

Install the sources of the driver in a directory and follow the instructions of the README file of the kit to create the modules necessary for the various kernel of the distributions.

# Log as root. (~root) # put the RedHat floppy boot disk to modify in the drive # you have to copy the initrd.img file from the floppy disk #mcopy a:initrd.img /tmp # then uncompress it #gzip -cd /tmp/initrd.img > /tmp/initrd.ext2 # Mount the "file" filesystem thus obtained #mount -t ext2 /tmp/initrd.ext2 /mnt/floppy -o loop # create a temporary directory #cd /tmp ; mkdir modules ; cd modules # uncompress and extract the modules provided #gzip -cd /mnt/floppy/modules/modules.cgz | cpio -ivdum # Copy the new updated module.

The LH4 doesn't seem to work correctly when not in Raid. Even with the latest Bios available at the time of the test (16.00), the problem remains. If you desactivate the Raid management, during the boot, the ncr53c8xx driver in Linux detects 4 controlers instead of 2 and boot doesn't end. To avoid that, you have to activate the Raid in the Bios and use each of the disk in Raid0 mode, which is quite the same as the solution without Raid at all.

These cards are equiped with an AMI Megaraid chipset and may support the following Raid levels : 0, 1, 3, 5, 10, 30 and 50. Some NetRaid cards, as well as the chipset integrated on the LH3 and LH4 mother boards are supported by recent version of the Linux kernel (2.0.36/2.2.19/2.4.3 typically - don't use 2.0.37/38).

For the RedHat 5.2 distribution, it's not possible to install the system on this type of controler, because it's not detected by the installation program. You have to use a specific floppy disk . This floppy disk should be used as input to the rawrite tool, for example. It works for systems with less than 1 GB of memory.

For the RedHat 6.0 distribution, you have to manually declare the existence of this card as a supplementary SCSI adapter, in order to use it directly during the installation. The megaraid driver isn't automatically detected.

To avoid strange messages during the boot printed by the megaraid driver, it's necessary to recompile it with the option -DHP (before kernel 2.4.2) or -DMEGA_HP_FIX (after).

For the RedHat 6.1 distribution, the megaraid driver provided by the kernel does support on ly the first logical drive. In order to obtain the others, please recompile a 2.4.3 standard kernel.

You have to note that the integrated card of the LH3/4 realises a software parity checks and performs thus less efficiently than the NetRaid daughter cards. On the other side, LH3000/6000 are equiped with an integrated card doing hardware checks.

In the fourniture of the driver provided by AMI there is a Raid management tool megamgr, usable within Linux, and equivalent to the tool included in the software embedded on the controler. It's downloadable from http://www.ami.com/support/prodsearch.cfm?InpProdID=17

In case of problem, a version is available there.

In addition to what is mentionned above, these models require a 1.14 version of the megaraid driver to work correctly. You may find a version of the sources of this driver there.

A driver disk for the RedHat distribution is available at the following address for the versions 6.2 and 7.0.

These cards are equiped with a StrongARM Chipset and correspond to the Adaptec card AAC-3642. A driver is available at http://domsch.com/linux. The RedHat 7.0 includes in standard the driver even if that release of the kernel doesn't handle it normaly. Information are also available on the Navigator L.19.00.

On these machines, when the second ide bus is probed by the kernel, there is a timeout, which doesn't hurt, but is useless. To avoid it, just add to your lilo.conf the following line :

append="ide1=noprobe"

To desactivate processors on a Linux server, you need to give an option during the boot to the kernel such as :

Lilo boot: linux maxcpus=3

where the number of processors given in option is less by one of the number of processors wanted. For example, here we activate 4 processors.

To use a High Availability Custer under Linux, you need to use additional software, such as :

• RSF-1 (Commercial)

• Linux-HA project (free) and ext3

Some of the PCs provided by HP are equiped with a multimedia keyboard. You may use the additional keys thanks to the HotKeys daemon (Cf:http://freshmeat.net/projects/hotkeys/)
