This page lists hardware known to work with Plan 9. Most hardware is listed by chipset: you may need to know what chipset your particular cards use. FLOPPY DISKS Plan 9 supports generic floppy drives, although some people have had trouble accessing them. If you have trouble accessing your 3.5" floppy drive and also have a 5.25" floppy drive, try disabling the latter in the BIOS. USB floppy drives are not supported. IDE/ATAPI DISKS Plan 9 supports almost all motherboard IDE/ATAPI controllers, but DMA transfers are only used on these recognized chipsets (chipsets not listed here will simply run slower; you can try turning on DMA by editing /sys/src/9/pc/sdata.c). * PC-Tech RZ1000 * Promise PDC20262 * CMD 640B * CMD 646 * VIA 82C686 * ServerWorks IB6566 * Intel 82371FB (PIIX) * Intel 82371SB (PIIX3) * Intel 82371AB (PIIX4) * Intel 82371EB (PIIX4E) * whatever the IBM Thinkpad T23 uses SCSI * Mylex Multimaster (old Buslogic BT-*) adapter * Symbios 53C8XX adapter CARDBUS AND PCMCIA CONTROLLERS The following cardbus controllers are supported: * Ricoh 476 PCI/Cardbus bridge * Ricoh 478 PCI/Cardbus bridge * TI PCI-1131 Cardbus controller * TI PCI-1250 Cardbus controller * TI PCI-1450 Cardbus controller * TI PCI-AC51 Cardbus controller If the cardbus chipset is not supported, Plan 9 falls back to the PCMCIA driver, which handles the Intel i82365, Cirrus Logic CL-PD6710, Cirrus Logic CL-PD6720, Vadem VG-46x, and compatibles. This covers most laptops. ETHERNET * 3Com Etherlink III, PCMCIA (3C589), Fast Etherlink, and Fast Etherlink XL adapters * Intel i82557, i82558, i82559 Fast Ethernet PCI LAN controller (e.g., the Intel EtherExpress PRO/100B) * Digital (now Intel) 21114x PCI Fast Ethernet controller (e.g., Digital DE-500). Some PNIC and PNIC2-based cards may also work with this driver. * AMD 79C970 PCnet PCI Ethernet controller (e.g., VMware) * National Semiconductor NE2000 or compatible adapter * Lucent Wavelan PCMCIA wireless ethernet adapter (including Dell TrueMobile 1150) * Intersil Prism-based wireless ethernet adapter (including Linksys Instant Wireless PC card) These cards are supported but not as well used: * Western Digital WD8003 * Western Digital WD8013 * SMC Elite and Elite Ultra * Linksys Combo EthernetCard and EtherFast 10/100 * Accton EtherPair-PCMCIA * Netgear FA410TX VGA CARDS AND CHIPSETS For VGA cards more than any other hardware, it is more precise to describe the chips we support rather than the cards they are based on, since the cards are more ephemeral than the chip sets. Beware: different revisions of a card may use different chip sets. Linux users can look at their X server configuration to see which chip set they are using. Windows users can look at ``control panel'' -> ``display settings'' -> ``display type'' to find out. Plan 9 uses some basic accelerator for features such as filling and scrolling rectangles. We use none of the 3D features on the cards we support. Chipsets used at Bell Labs: * ATI Mach64xx * Cirrus Logic CL-GD542x, CL-GD543x, CL-GD544x, CL-GD546x Laguna * Trident Cyber938x * CHIPS hiQVideo (65550, 65554, 69000) * Neomagic MagicGraph * S3 Savage4, Savage IX/MV, SuperSavage IXC/16 * S3 ViRGE DX, GX, GX2, MX, VX * 3Dfx Voodoo 3 1000, 2000, and 3000 * Nvidia TNT * Matrox G400 * VMware virtual chipset Chipsets supported in previous releases but not tested in current system: * XXX Cards used at Bell Labs: * XXX Cards used elsewhere and tested with the release: * (none yet) Cards supported in previous releases but not tested in current system: * XXX AUDIO Supported audio devices: * Sound Blaster 16 or later, ISA card * ESS 1688 running in 8-bit SBPro mode * most USB audio devices Supported but not as well used: * Any Sound Blaster 16 clones (NOT Sound Blaster Pro clones) KEYBOARDS Any PS/2 keyboard should work. MICE Plan 9 supports PS/2 and PS/2 Intellimouse mice as well as serial mice using the Logitech or Microsoft serial mouse protocols. There is preliminary support for the scroll wheel and extra buttons as on the Toshiba Protégé 3440CT. Most laptops present their built-in pointing devices as PS/2 mice. LAPTOPS Laptops are often the hardest systems to get Plan 9 running on, because you can't choose the hardware piece by piece. The following laptops are known to work in the current release: * IBM Thinkpad 560, X20, T23 * NEC Versa LX, SX * Toshiba Portégé 3440CT The following laptops worked in previous releases and may work in the current one: * AT&T GIS Globalyst 250 * NEC Versa 6030X, 6200MX
