Document Conventions --- -------------------- - -We have `underlined' text which represents user input with `-' -symbols throughout this document to differentiate it from -the machine output. - -1. Using UserConfig to change FreeBSD kernel settings --- -------------------------------------------------- - -The UserConfig utility allows you to override various settings of -the FreeBSD kernel before the system has booted. This allows you to -make minor adjustments to the various drivers in the system without -necessarily having to recompile the kernel. - -UserConfig is activated by specifying the `-c' flag at the initial -boot prompt. For example: - - >> FreeBSD BOOT @ 0x10000: 640/7168 k of memory - Use hd(1,a)/kernel to boot sd0 when wd0 is also installed. - Usage: [[wd(0,a)]/kernel][-abcCdhrsv] - Use ? for file list or press Enter for defaults - - Boot: -c - -- - -This command causes the system to boot the default kernel ("/kernel") and -the UserConfig utility to be started once the kernel is loaded into memory. - -The `-c' flag follows any of the other parameters you may need to provide -for the system to boot properly. For example, to boot off the second of -two SCSI drives installed and run UserConfig, you would type: - - Boot: sd(1,a)/kernel -c - ----------------- - -As always, the kernel will report some information on your processor -and how much memory your system has. Then UserConfig will be invoked -and you will see the prompt: - - config> - -To see the list of commands that UserConfig accepts, you may type '?' and -press [ENTER]. The help message looks something like this: - -Command Description -------- ----------- -attach <devname> Return results of device attach -ls List currently configured devices -port <devname> <addr> Set device port (i/o address) -irq <devname> <number> Set device irq -drq <devname> <number> Set device drq (DMA Request) -iomem <devname> <addr> Set device maddr (memory address) -iosize <devname> <size> Set device memory size -flags <devname> <mask> Set device flags -enable <devname> Enable device -probe <devname> Return results of device probe -disable <devname> Disable device (will not be probed) -quit Exit this configuration utility -help This message - - -You may alter nearly all of the default settings present in the FreeBSD -generic kernel. This includes reassigning IRQs, disabling troublesome -devices (or drivers that conflict with the hardware your system has), -setting special device flags, etc. - -The most common use of UserConfig is to adjust or disable a driver -which is causing trouble. The "ls" command displays the current -settings for all the drivers present in the booted kernel, and -once you have located an entry of interest you may use the displayed -device name to change its settings or even disable the driver completely. - -For example, to change the memory address of network adapter 'ed0' to -the address 0xd4000, you would type - - config> iomem ed0 0xd4000 - ----------------- - -To entirely disable a device driver you are not using, use the -"disable" command. In this example, you would disable device -`ie0' by typing: - - config> disable ie0 - ----------- - -You can use the "ls" command to verify your changes and correct -any other problems before continuing the boot process. - -Once you are happy with a given configuration you may type: "quit" - -This will cause the kernel to boot with the new settings you -have chosen. - -Once you have a fully installed system (e.g. the `bin' distribution -has been successfully extracted), any changes you make in UserConfig -are permanently stored in the `/kernel' file on the root filesystem. -This action is performed by the `dset' utility, which will ensure that -these settings remain in effect until you replace the kernel with -a new one. If you do not want your changes to be permanently -stored like this, remove `dset' from the /etc/rc file before you -make any changes. - -If you accidentally change a setting for a device that you did not mean -to change, the safest thing to do is to reset the computer and start -over. Do not allow the boot to proceed (e.g. do not type "quit") with -bad settings as these may be permanently stored by dset and -leave your system in a state where it will no longer run properly. - -We suggest as a general rule that you disable any drivers that are not -used by your particular hardware configuration. There are known problems -with certain device drivers (see section 4.0) that can cause conflicts -with other devices if they're also not disabled. You should move or -disable any device that resides at the same port or IRQ as a device -you actually have! - -You can also remove drivers that are not needed by building yourself a -custom kernel that contains only the device drivers which your system -really needs (see section 6.0 of the FreeBSD.FAQ). If your system has -sufficient free disk space to store and compile the kernel sources, -this is the option we most highly recommend. - - - -2. Default (GENERIC) Configuration --- ------------------------------- - -The following table contains a list of all of the devices that are present -in the GENERIC kernel, which is the kernel (the operating system) that was -placed on your computer during the FreeBSD installation process. -(A compressed version of the GENERIC kernel is also used on the -installation floppy diskettes.) - -The table describes the various parameters used by the driver to communicate -with the hardware in your system. There are four parameters in the -table, but not all are used by each device. They are: - - Port the starting I/O port used by the device, shown in hexadecimal. - - IOMem the lowest (or starting) memory address used by the device, - also shown in hexadecimal. - - IRQ the interrupt the device uses to alert the driver to an event, - given in decimal. - - DRQ the DMA (direct memory access) channel the device uses to move - data to and from main memory, also given in decimal. - -If an entry in the table has `n/a' for the value, it means that the -parameter does not apply to that device. A value of `dyn' means that the -correct value should be determined automatically by the kernel when the -system boots. - - -FreeBSD GENERIC kernel: - - Port IRQ DRQ IOMem Description - ---- --- --- ----- --------------------------------- -fdc0 3f0 6 2 n/a Floppy disk controller -wdc0 1f0 14 n/a n/a IDE/MFM/RLL disk controller -wdc1 170 15 n/a n/a IDE/MFM/RLL disk controller - -ncr0 n/a n/a n/a n/a NCR PCI SCSI controller -ahc0 n/a n/a n/a n/a Adaptec 294x PCI SCSI controller -bt0 330 dyn dyn dyn Buslogic SCSI controller -uha0 330 dyn 6 dyn Ultrastore 14f -ahc1 dyn dyn dyn dyn Adaptec 274x/284x SCSI controller -ahb0 dyn dyn dyn dyn Adaptec 174x SCSI controller -aha0 330 dyn 5 dyn Adaptec 154x SCSI controller -aic0 340 11 dyn dyn Adaptec 152x/AIC-6360 SCSI - controller -nca0 1f88 10 dyn dyn ProAudioSpectrum cards -nca1 350 5 dyn dyn ProAudioSpectrum cards -sea0 dyn 5 dyn c8000 Seagate ST01/02 8 bit controller - -wt0 300 5 1 dyn Wangtek and Archive QIC-02/QIC-36 - -mcd0 300 10 n/a n/a Mitsumi CD-ROM -mcd1 340 11 n/a n/a Mitsumi CD-ROM - -matcd0 dyn n/a n/a n/a Matsushita/Panasonic CD-ROM - -scd0 230 n/a n/a n/a Sony CD-ROM - -sio0 3f8 4 n/a n/a Serial Port 0 (COM1) -sio1 2f8 3 n/a n/a Serial Port 1 (COM2) -sio2 3e8 5 n/a n/a Serial Port 2 (COM3) -sio3 2e8 9 n/a n/a Serial Port 3 (COM4) - -lpt0 dyn 7 n/a n/a Printer Port 0 -lpt1 dyn dyn n/a n/a Printer Port 1 -lpt2 dyn dyn n/a n/a Printer Port 2 - -de0 DEC DC21x40 PCI based cards - (including 21140 100bT cards) -ed0 280 5 dyn d8000 WD & SMC 80xx; Novell NE1000 & - NE2000; 3Com 3C503 -ed1 300 5 dyn d8000 Same as ed0 -eg0 310 5 dyn dyn 3Com 3C505 -ep0 300 10 dyn dyn 3Com 3C509 -ie0 360 7 dyn d0000 AT&T StarLAN 10 and EN100; - 3Com 3C507; NI5210 -ix0 300 10 dyn d0000 Intel EtherExpress cards -le0 300 5 dyn d0000 Digital Equipment EtherWorks - 2 and EtherWorks 3 -lnc0 280 10 n/a dyn Lance/PCnet cards - (Isolan, Novell NE2100, NE32-VL) -lnc1 300 10 n/a dyn See lnc0 -ze0 300 5 dyn d8000 IBM/National Semiconductor - PCMCIA Ethernet Controller -zp0 300 10 dyn d8000 3Com PCMCIA Etherlink III - Ethernet Controller ---- End of table --- - - -If the hardware in your computer is not set to the same settings as -those shown in this table and the item is not marked 'dyn', you will -have to either reconfigure your hardware, or use UserConfig ('-c' boot -option) to reconfigure the kernel to match the way your hardware is -currently set (see section 1.0). - -If the settings do not match, the kernel may be unable to locate -or reliably access the devices in your system. - - - -3. LINT - other possible configurations --- ------------------------------------ - -The following drivers are not in the GENERIC kernel but remain -available to those who do not mind compiling a custom kernel (see -section 6 of FreeBSD.FAQ). The LINT configuration file -(/sys/i386/conf/LINT) also contains prototype entries for just about -every device supported by FreeBSD and is a good general reference. - -The device names and a short description of each are listed below. The port -numbers, etc, are not meaningful here since you will need to compile a -custom kernel to gain access to these devices anyway and can thus -adjust the addresses to match the hardware in your computer in the process. -The LINT file contains prototype entries for all of the below which you -can easily cut-and-paste into your own file (or simply copy LINT and edit -it to taste): - -apm: Laptop Advanced Power Management (experimental) -ctx: Cortex-I frame grabber -cx: Cronyx/Sigma multiport sync/async -cy: Cyclades high-speed serial driver -el: 3Com 3C501 -fe: Fujitsu MB86960A/MB86965A Ethernet cards -fea: DEV DEFEA EISA FDDI adater -fpa: DEC DEFPA PCI FDDI adapter -gp: National Instruments AT-GPIB and AT-GPIB/TNT board -gsc: Genius GS-4500 hand scanner -gus: Gravis Ultrasound - Ultrasound, Ultrasound 16, Ultrasound MAX -gusmax: Gravis Ultrasound MAX (currently broken) -gusxvi: Gravis Ultrasound 16-bit PCM -joy: Joystick -labpc: National Instrument's Lab-PC and Lab-PC+ -mpu: Roland MPU-401 stand-alone card -mse: Logitech & ATI InPort bus mouse ports -mss: Microsoft Sound System -nic: Dr Neuhaus NICCY 3008, 3009 & 5000 ISDN cards -opl: Yamaha OPL-2 and OPL-3 FM - SB, SB Pro, SB 16, ProAudioSpectrum -pas: ProAudioSpectrum PCM and MIDI -pca: PCM audio ("/dev/audio") through your PC speaker -psm: PS/2 mouse port -rc: RISCom/8 multiport card -sb: SoundBlaster PCM - SoundBlaster, SB Pro, SB16, ProAudioSpectrum -sbmidi: SoundBlaster 16 MIDI interface -sbxvi: SoundBlaster 16 -spigot: Create Labs Video Spigot video-acquisition board -uart: Stand-alone 6850 UART for MIDI -wds: Western Digital WD7000 IDE - ---- end of list --- - - -4. Known Hardware Problems, Q & A: --- ------------------------------- - -Q: mcd0 keeps thinking that it has found a device and this stops my Intel - EtherExpress card from working. - -A: Use the UserConfig utility (see section 1.0) and disable the probing of - the mcd0 and mcd1 devices. Generally speaking, you should only leave - the devices that you will be using enabled in your kernel. - - -Q: The system finds my ed network card, but I keep getting device - timeout errors. - -A: Your card is probably on a different IRQ from what is specified in the - kernel configuration. The ed driver will no longer use the `soft' - configuration by default (values entered using EZSETUP in DOS), but it - will use the software configuration if you specify `?' in the IRQ field - of your kernel config file. The reason for the change is because the - ed driver used to read and try to use the soft configuration information - even when the card was jumpered to use a hard configuration, and this - caused problems. - - Either move the jumper on the card to a hard configuration setting - (altering the kernel settings if necessary), or specify the IRQ as - `-1' in UserConfig or `?' in your kernel config file. This will - tell the kernel to use the soft configuration. - - Another possibility is that your card is at IRQ 9, which is shared - by IRQ 2 and frequently a cause of problems (especially when you - have a VGA card using 2! :). You should not use IRQ 2 or 9 if at - all possible. - - -Q: I go to boot from the hard disk for the first time after installing - FreeBSD, but the Boot Manager prompt just prints `F?' at the boot menu - each time but the boot won't go any further. - -A: The hard disk geometry was set incorrectly in the Partition editor when - you installed FreeBSD. Go back into the partition editor and specify - the actual geometry of your hard disk. You must reinstall FreeBSD - again from the beginning with the correct geometry. - - If you are failing entirely in figuring out the correct geometry for - your machine, here's a tip: Install a small DOS partition at the - beginning of the disk and install FreeBSD after that. The install - program will see the DOS partition and try to infer the correct - geometry from it, which usually works. - - -Q: I have a Matsushita/Panasonic CD-ROM drive but it isn't recognized - by the system, even if I use UserConfig to change the Port address to - 630, which is what my card uses. - -A: Not all of the companies that sell the Matsushita/Panasonic CR-562 - and CR-563 drives use the same I/O ports and interface that the - matcd driver in FreeBSD expects. The only adapters that are supported - at this time are those that are 100% compatible with the Creative - Labs (SoundBlaster) host interface. See matcd.4 documentation for a - list of host adapters that are known to work. - - -Q: I'm trying to install from a tape drive but all I get is something like: - st0(aha0:1:0) NOT READY csi 40,0,0,0 - on the screen. Help! - -A: There's a limitation in the current sysinstall that the tape MUST - be in the drive while sysinstall is started or it won't be detected. - Try again with the tape in the drive the whole time. - - -Q: I've installed FreeBSD onto my system, but it hangs when booting from - the hard drive with the message: ``Changing root to /dev/sd0a''. - -A: This problem may occur in a system with a 3com 3c509 ethernet adaptor. - The ep0 device driver appears to be sensitive to probes for other - devices that also use address 0x300. Boot your FreeBSD system by power - cycling the machine (turn off and on). At the ``Boot:'' prompt specify - the ``-c''. This will invoke UserConfig (see Section 1. above). Use - the ``disable'' command to disable the device probes for all devices - at address 0x300 except the ep0 driver. On exit, your machine should - successfully boot FreeBSD. - - -Q: My system hangs during boot, right after the "fd0: [my floppy drive]" - line. - -A: This is not actually a hang, simply a very LONG "wdc0" probe that - often takes a long time to complete on certain systems (where there - usually _isn't_ a WD controller). Be patient, your system will boot! - To eliminate the problem, boot with the -c flag and eliminate the wdc0 - device, or compile a custom kernel. - -[ Please add more hardware tips to this Q&A section! ] |
