Summary: Introduced the meaning of the FreeBSD kernel parameters, give us a custom-compliant FreeBSD kernel to provide reference #
# Generic - Generic Machine Kernel
#
## Host type I386 Because FreeBSD is running on x86
Machine "i386"
## CPU Type Look at yourself a few 86
#CPU "i386_cpu" # 386's computer
#CPU "i486_cpu" # 486's computer
CPU "i586_cpu" # 586's computer
#CPU "i686_cpu" # 686's computer
## 内 Nuclear ID No special meaning
Ident generic
## Defines how much the structure of the system should retain how much memory space, usually
## 16 or 32 is enough, unless you open, or use 64
## Pay attention to this value is less than your memory number
MAXUSERS 32
## A number of processes that users can perform
Options child_max = 256
## A file limit that users can open
OPTION OPEN_MAX = 256
## Open the kernel debugging, the average person can not use
#options ddb
## Allow debugging memory cells (seek KTRACE, KDUMP for details), or leave it to the kernel hacker
#options Ktrace #kernel Tracing
## No FPU (SX) friends, people with dx are not available
#oPtions Math_emulate #support for x87 emulation
## You have 64MB or more, specified units are k, for example, 128MB RAM
#options "MaxMem = (128 * 1024)"
## Support the network, must have a nonsense
Options inet #interneetworking
## i i 相关 相关 agreement
#options ipx # ipx / spx communications protocols
#options ipxip #ipx in ip encapsulation (Not Available
#options ptunnel #ip in ipx encapsulation (Not Available
#options ipxprintfs = 0 # ipx / spx console debugging information
#options ipx_errprintfs = 0 # ipx / spx console debugging information
## File System Settings
## Only UFS is required, the other can do not have to use the Kernel to load with LKM.
## Note that the file system is named with a double quotes, and see the Linux file system below.
Options FFS #Berkeley Fast FileSystem
#options NFS #Network FileSystem
#options NFS_NOSERVER #disable the NFS-Server Code.
#options msdosfs # msdos FileSystem
#options "CD9660" #iso 9660 FileSystem
#options procfs #Process FileSystem
#options kernfs #kernel FileSystem
#options nqnfs #enable nqnfs lese checking
#options fdesc #file descriptor FileSystem
#options LFS #Log FileSystem
#options MFS #Memory File System
#options Nullfs #Null FileSystem
#options portal #portal FileSystem # Options umapfs #uid map FileSystem
#options union # ion filesystem
#options devfs #devices FileSystem
##
## Friends with Linux file systems pay attention to use the following line
#options "ext2fs" # ext2fs, only in 2.2-current
## 4.3BSD compatibility, this is necessary, some programs can be used
Options "compat_43" #compatible with BSD 4.3
## Execute Linux program file Even if you use LKM to load, you still need this parameter.
## You can modify Linux = Yes in / etc / sysconfig or execute / usr / bin / linux
## Pair you must install Linux_lib in package
#options "compat_linux" #Linux Emulator
## SCO Binary Simulation
#options "ibcs2"
## When starting, the SCSI card will wait for the equipment to prepare for a few seconds, for some slow SCSI devices,
## If the CDROM is needed, the minimum is 2, choose the right value for you.
Options "SCSI_DELAY = 4" #be Pessimistic About Joe SCSI Device
## Allow users to intercept console information for the procedures for Xconsole, are necessary
Options uconsole #unix console
## Virtual console maximum, Alt-f1 to ALT-F12, etc., just define the upper limit
## Virtual console required to see / etc / ttys definition Vty
## This value is 16
Options "Maxcons = 8" #max number for Virtual Console
## For Wine (MS-Windows Emulator)
#options user_ldt #for Wine, MS-Windows Emulator
## Use the quota limit
#options quota #for quotas
## sysv ipc / shm (BBS needs to be used with X-window and compat_linux), this is necessary
Options sysvmsg, sysvsem, sysvshm #for SYSV-IPC
## LKM loader, this is necessary (abolished in 2.1.5r has been abolished into an internal parameter)
#options Lkm #Loadable Kernel Module Loader
## If you use the ISA's SCSI card, there is more than 16MB of memory, you must open this item, otherwise you can't
## Use> 16MB memory. If you are using the SCSI card of Eisa / VL / PCI, you don't need it.
## Open it will reduce a little speed, nothing, don't open (it is not available with IDE)
#options bounce_buffers #include support for Dma Bounce Buffers
## To use ip-firewall, you can use LKM to load
#options ipfirewall #firewall code
#oPtions ipfirewall_verbose #print Information About Dropped Packets

## To use ip-firewall or as Router
## After 2.2-960323-SNAP, it has been abolished and opened in sysctl (see / etc / sysconfig)
