The availablility and lack of licensing restrictions of source code for the Linux kernel, has allowed Linux to be ported to a plethora of processors. There are the most popular for desktop, laptop and servers:
- Intel - Pentium (desktop)/Xeon (server) x86, x86-64, Itanium, Alpha
- IBM PPC (Power PC)
- YoLinux: List of Hardware Ports
RAM heat sinks:
- SRAM: Static RAM (SIMMS connector)
- DRAM: Dynamic RAM. Typically 70 ns. Can only read or write but not both at the same time. (DIMMS connector)
- EDO DRAM: Extended Data Output DRAM
- SDRAM: Synchronous Dynamic RAM. (PC100 compatable) Typically 10ns. DIMM module has 168 pins.
- RDRAM: Rambus DRAM. Requires motherboard chipset support. (RIMMS connector)
- DDR/DDRAM: Double Data Rate/Double Data RAM. Operates twice as fast as conventional memory by performing two memory operations for every CPU clock cycle. (PC133 SDRAM compatable) DDR DIMM module has 184 pins.
- DDR266: Double Data Rate at 266 Mhz. Throughput=8bytes x 266 Mhz/sec = 2.1 GB/sec. Hence the term: PC2100
My choices for best video graphics are:
- NVidia: - Best 3-D support,
chip-set based graphics cards
Quadro (high end CAD), GeForce (PC) and Quadro nView (dual monitor support Quadro)
NVidia based graphics cards are by far the best for Linux because of 3D performance, 3D GL and GLX (SGI X-window/GL interface) support, and X-window DRI support. NVidia is the best for 2D video playback of video files and DVD's because of the Xv (Xvideo), and Xrender support. (fast screen access) In order to enable this support one must download the NVidia binary "Accelerated Linux Driver Set" from the NVidia web site and the modified Linux Kernel RPM. (See the YoLinux kernel RPM install Tutorial) Source for the modified kernel is also available from their site. This is NOT included in the Red Hat distribution. Note that this applies to XFree86 4.0+ which supports these X-window extensions. (Red Hat 7.0+)Also see:
- NVidia list of available Linux drivers
- NVIDIA Accelerated Linux Driver Set installation instructions.
- LDP: NVidia HowTo
- YoLinux.com: Dual monitor NVidia configuration
List of popular graphics boards manufacturers which use the NVidia chipset:
- Albatron Technology, Co. Ltd
- ASUS Computer International
- Chaintech Computer Co. Ltd.
- eVGA.com Corporation - Dual DVI monitor GeForce 7800 GT
- Gainward Co., Ltd.

Video Capture and TV cards:
- Hauppague analog WinTV bt 878 (Brooktree chip-set) - Hauppauge Linux support page
I purchased the Hauppauge model 447 which includes a PCI WinTV television and FM radio tuner card, video camera, FM antenna, an internal sound card connector and an infrared remote. The TV tuner card is cable-ready, supports 125 channels and closed captioning. The card is capable of supporting a resolution of 1,600 x 1,200 pixels, and has S-Video input, audio in/out (1/8" = 3.5mm, 3 conductor minijack), coax connectors for cable TV and FM radio cable/antenna inputs well as a remote control (IR) reciever socket (2.5mm minijack). An external IR reciever is also included. (Newr versions include headphones with mic and volume control.)
This capture card works with qVIX Video conferencing for Linux
The prefered Hauppauge video camera has an S-video or RCA video connection such as the:
- Hauppauge XC77B/44x (supplied with the Hauppauge WinTV 447)
- Hauppauge 338
- X10 Wireless video cameras - 2.4 Ghz
- Pixera - The PXG-100 (N-NTSC or P-PAL) ship with newer models of the 447.
- Swann - small
The default Red Hat 7.1 kernel comes ready to support TV/Video. If compiling the kernel, note that it requires the following modules: I2C Core, I2C Devices, I2C Algorithms, Video4Linux (v4l) API driver, Bttv drivers (this includes everything required for TV, radio and teletext) and Bttv mixer device (from the sound section).

The winner these days seems to be Intel. They also manufacture the Intel Pro/100 Dual port server adapter which has two 10/100 Mbps Ports. This can be used to increase bandwidth, enable routing or setting up a firewall (ipchains/iptables) and only use one PCI slot. See Using Linux and ipchains/iptables to set up an internet gateway for home or office. In the near future Intel will present I2O (Intelligent I/O) NICs which are supported by the current Linux kernel. This will offload the TCP/IP stack to the network card reducing the CPU load. This will be essential in supporting iSCSI (network SCSI storage)
- Intel - Pro 1000 and Pro 1000 Dual Port
- Intel - Pro 100 and Pro 100 Dual Port:
This PCI NIC card supports two physical ethernet connections (eth0, eth1) on one card conserving valued PCI slots. Great for a firewall set-up.

Other network hardware:
- Logitech wireless "Cordless iTouch" or "Cordless Freedom Pro" mouse and keyboard. An RF receiver plugs into the regular PS/2 keyboard and mouse ports on your computer. (USB mouse connection is also available) The keyboard and mouse are wireless using radio technology. The mouse is a two button mouse with middle scroll wheel. (As a programmer, I prefer three button mice for UNIX workstations.)

The Creative Labs Sound Blaster Audigy or Live PCI with output for digital speakers is about as good as it gets. This is not because it's the best sound card, it's because it's the best supported. I tried to get fancy with a Turtle Beach and as far as I got was being able to play my CD and that was it. (I basically failed and ended up buying a Sound Blaster) If you want to get fancy you may have to buy commercially supported drivers from 4Front using Open Sound System (OSS). (Note: Most other references to OSS refer to Open Source Software) See the 4Front list of supported cards.

- Plextor - CD-RW
32X/12X/10X REWRITABLE EIDE CD-RW Internal
I mention the Plextor because all the others are so much alike and this one stands out. It has the fastest write throughput, available in Ultra-SCSI and comes with "BURN-Proof" features which allow it to stop in the middle of burning a CD. This is unique to Plextor. It has been ranked the best by all the reviews I have seen.

There are only two manufacturers with licensed software support of DVD system for Linux.

- IBM: IBM Thinkpad notebook computers with Linux pre-installed and a DVD come with the InterVideo, LinDVD player installed and configured.
There is DVD player software available for Linux but its legality has been under attack in the courts. The battle has not been resolved and unless the Linux DVD developers lose the battle, the OMS (Open Media System) software is available from: http://linuxvideo.org
- The DVD disk must be mounted: mount /dev/cdrom /mnt/cdrom
- Use the hdparm command to enable DMA access to the DVD drive or
else video playback will seem slow, broken and ragged.
i.e.: hdparm -d1 -c1 /dev/cdrom
Also see YoLinux: System Optimization and hdparm
- New DVD players do not have a country code burned in. Burn this in with specialized Linux software or run it under Windows once before use under Linux.
- Requires udf file system support in kernel.
- When compiling OMS from source, bootstrap with autogen.sh to create a configure file, then run configure and make.
