U ISOLINUX produced along SYSLINUX {alternativelya

First, the guide profiles programs for anyone operating system on anybody one hardware platform to run the process requires a guide,GHD Deluxe Midnight 2011, that is, initialization software environment, the kernel into memory from the storage media were to go, and start running. Of course, fknow next to nothing ofme simple software and hardware systems, this process may and simple, and slightly more complicated fhardly everme of the PC will.
PC on the order of the boot process BIOS, then beneath the kernel initialization code, notwithstanding once a machine is not run only once, leaving traces, but still quite important. All of the boot program are act alike things:
stay in the special position of arsenal media can be BIOS boot, or that he is a system executable file that can be consumer explicitly or implicitly in the system (host system) within the boot; understand the need to be launched starting location of the file, including the system kernel, ramdisk, etc., and peruse them out, being fraught into memory; tectonic surroundings,GHD Straighteners NZ, running the operating system kernel, himself this stage of history. Historically, most noted for the Linux bootloader than LILO and Grub, and as a general navigate the process, either warmhearted used, but fknow next to nothing ofme special causes, such as the boot program can use the limited space for removable arsenal media (layman's terms, including CD-ROM, floppy disk, u disk, etc.), they are a mini too thick and cumbersome, which leads to today's hero --- SYSLINUX / ISOLINUX, now, you equitable know they are ample to adviser the process, Next, we need to insert some rubbish.
Second, initrdinitrd = init ramdisk, the name suggests, is to start using a RAM disk, it is a system wide hardware patronize of necessities.
we know, Linux is a kernel driver part,GHD IV Straighteners, they invest the hardware to the altitude of the abstract interface, Linux kernel subsystem --- the essence part of the work of the virtual file system strongly depends on the underlying hardware driver support, In the startup process, when some of the necessary drivers can not use it, such as the EXT2 file system, IDE hard disk adapter, and can not work, system boot will stop this, the accident of the so-called `` Kernel Panic'', which Beginners kernel is the most common difficulties encountered.
However,GHD Precious Gift Set, we certainly can not put all the drivers are compiled into the kernel were to go, for we can not indefinitely boost
the size of the kernel, which for system resources, especially in the boot process is very limited storage resources obtainable is unbearable that we can put a lot of drivers compiled as modules, as used with the load in infrequent cases, certain modules are conflicting, such as among some versions of 2.4 kernel, reiserfs and ext3 driver can not be both were compiled into the kernel. Therefore, we can only put in the kernel drivers required, and the rest is not much chapter of the compiled module into / lib / modules / `uname-r` / being, when needed will be loaded.
However, for a universal kernel, it is complicated to decide which of several drivers out of real absence, and what is the IDE disk master Intel or AMD / nVidia's, or VIA,GHD Pink Limited Edition, and even the Fibre Channel SCSI disk ... ... Yeah, this is actually a quite troubled person's problem, not a driver can come from less space, the absolute requirement to cope with all the equipment, so we stable for the media seeking a middle --- ramdisk
ahead the start of the kernel, the boot agenda first in memories to build a ramdisk, as a elementary file system, then Linux kernel in mandate to start their own root file system, so that you can not bypass the benefits of disk drive problems As long as drivers ramdisk on it.
with ramdisk starts, the startup script in the ramdisk (ordinarily shrieked / linuxrc) within the try because the hardware inside the ramdisk / lib / modules / `uname-r` /, load the applicable driver, then the system has been with the switch to the hard disk or other media file system above the condition of the.
missed, this time, we first load the disk or CD-ROM, u disk, and other boot media and the media to set the root partition, and run the init process is a process, then, in the init script, freed initrd space, this is the use of initrd boot process. In this process the boot process to assist us do one entity --- build ramdisk, the initrd into memory.
three, with SYSLINUX / ISOLINUX boot floppy and CD-ROMs have yet said on, SYSLINUX / ISOLINUX is designed to guide the lightweight removable media boot process, because the media do not usually only for a firm hardware, initrd course SYSLINUX / ISOLINUX must support the function. Both the boot process is the same, there is not much difference, but on different boot appliance nobody extra.
3.1 configuration SYSLINUX / ISOLINUX guidance for both programs will have a boot code, boot code, when written, but also need a configuration file: syslinux.cfg / isolinux.cfg, the same, these two documents is the same, only difference is the file name, its manifold fields are written as usual:
DISPLAY xxx.txt
This specifies a file name, ambition startup display the contents of the file tin even contain a graphics file RLE encoded, namely is while we start apt discern the installation CD that; but this field is not major, we skipped over.
DEFAULT linux
label is specified for the default linux boot option, of course, could be someone another.
LABEL linux
kernel vmlinuz
; appbring an end to ...itrd = initrd26.gz ramdisk_size = 1000000 vga = 791
description This is a start, in front of the label we entire know, and then specify the kernel and are kernel parameters, 1 of the important parameter is specified initrd = initrd file and initrd ramdisk_size = specifies the size restrict. The recess of the kernel parameters may too have a lot, but here the contention that we can generally be copied over. This startup option can be described as a number of.
PROMPT = 1
it is said, to prompt the user choose the default option is to instantly enter the
; TIMEOUT = 0
no time limit, of course, later a definite period of time can be specified automatically enter the default option.
nice to so numerous, and whether you use LILO, then certainly with this handy, to be credible grub is also not many another.
3.2 Installing SYSLINUX / ISOLINUX finished the configuration document, and now entered a substantive stage, where a delicate distinction between the 2 bootstrap, premier introduced SYSLINUX:
first formatted as FAT16 format boot media (floppy disk appears to be FAT12), our instance is the U disk,
mkdosfs-F16-I / dev / sda
we are operating the U disk,GHD Carry Case & Heat Mat, preferably than inside the merely a partition, not many see this situation, only the hands of the U disk is prefer special, in maximum cases, we can
mkdosfs-F16 / dev/sda1
and then hung in the U disk, into our syslinux.cfg and the kernel and initrd.gz, there are other material needed to start and then umount the U disk.

* fulfil the following actions, you must umount U disk! *

Then jot the boot sector:
syslinux / dev / sda (or syslinux / dev/sda1, if it is formatted / dev/sda1, then )
this point is complete.
for the CD-ROM, and are not difficult, we use ISOLINUX:
ISO directory in the arrangement of creation to join a subdirectory, such as the boot / isolinux /, then put into isolinux.cfg and a CD-ROM are the same for all the isolinux available boot media isolinux.binary, of course, into the appropriate kernel, initrd, etc., and then, when the product of iso-b parameters to be used:
mkisofs - o output.iso
-b boot / isolinux / isolinux.bin-c boot / isolinux / boot.cat
-no-emul-boot-boot-load-size 4-boot-info-table
; for-iso-dir /
last parameter is the specified directory of the CD-ROM,-c parameter of the file is automatically generated, do not worry also many almost the other parameters are nailed. In fact, constantly been accustomed isolinux / rather than the boot / isolinux /, this is conventional, you can use your own. The way here is relating to the root of the disc, and disc and production the going catalogue does not stuff.
this point, you will use SYSLINUX / ISOLINUX out. :)
Four combat --- curse small linux + debian installer, 2 in 1 usb disk1 download di the hd-image in the kernel image and initrd, into the U disk, when the businesscard iso too into them, from the iso find isolinux.cfg, Kai set down inside 2 download dsl, the KNOPPIX directory shook to our U-disk, the boot / isolinux / initrd inside the kernel image and also into the U disk root directory, then , U root directory in the same time there are two startup files, and also memorize the dsl isolinux.cfg inside the boot options. 3 to one of the isolinux.cfg based, to join dissimilar startup parameters, do not pay attention to label the clash a name on it. 4 umount U disk, U disk and then run syslinux, to write boot sector, you're done. If the before post said, dsl the initrd being, only the search / dev / sda [1-9] without search
/ dev / sda, so, if, if, as we are forced to use / dev / sda, then dsl must alteration it inside the initrd linuxrc, and in counting, there is no other worthy of letters of the the.
