Energy-saving dual operating systems notebook computer
Technical field
The invention belongs to field of computer technology, be specifically related to a kind of energy-saving notebook computer with dual operating systems.
Background technology
Along with the development of notebook computer with popularize, the mobile computing technology just more and more receives publicity and payes attention to.For the user, what they needed is the computing machine that service can both be provided at any time and any place, and therefore notebook computer is born just.Nowadays, the battery that notebook computer carries has solved in the problem that does not have operate as normal under the situation of external power supply, has broken the restriction on the traditional computer space.But because the restriction of technology of battery own and material adds the high power consumption of computing machine, these batteries generally can only provide 1-2 hour operate as normal power supply, and the limitation of time is still fairly obvious; And along with the increase of charging times, the live amount of battery more can reduce even complete failure gradually.
Address this problem, following two kinds of approach are arranged: the one, from battery itself, by changing material or improving live amount and the durability degree that manufacture craft increases battery.But as things go, this is difficulty very, because the battery manufacturing industry comes to the ripening period, being difficult to has so great breakthrough at short notice.Another approach is exactly to reduce the whole power consumption of computing machine, and its prerequisite must be not reduce computing power certainly.
Summary of the invention
The objective of the invention is to propose a kind of energy-saving notebook computer that reduces the computing machine whole power consumption.
By anatomizing the power consumption of each parts of computing machine, we find that the hard disk of mechanically working has accounted for wherein very most of.On the other hand, through a large amount of investigation, we find the user used in most of times be nothing but some the most frequently used functions, for example send and receive e-mail, network browsing, text-processing etc., and these operations are not high to the requirement of hardware.Given this, the scheme of the energy-saving notebook computer of the present invention's proposition is as follows: this notebook computer is mounted with two cover operating system, i.e. primal system and Mobile operating systems.What particularly point out is that said here operating system is a kind of system of hardware and software combination.As carrier, power consumption has only 1/tens of hard disk to described Mobile operating system with common USB flash disk, and noiselessness, failure rate are low, and it almost comprises all application programs commonly used above-mentioned, and need not plug and play is installed.Described primitive operation system comprises some high-end applications programs.In actual applications, the user in most of the cases only needs to use the Mobile operating system of low power consumption to get final product, and only when needs are used some high-end applications programs, just uses the primitive operation system of high power consumption, has so just realized target energy-conservation, power saving.
Linux system after can integrated improvement in the Mobile operating system among the present invention.Therefore, system supports graphical interfaces, multimedia is browsed is connected with network, can satisfy most users' basic demand, and the user can use these functions on any notebook computer.
The present invention has fully taken into account the demand in computer nowadays market, and has the following advantages:
(1) energy saving is lengthened working hours
The use of this invention has solved the battery problems of notebook computer substantially, makes notebook under the situation of no external power supply, and the working time has increased several times.Simultaneously, battery life also can prolong because the charging interval increases.
(2) noiselessness, failure rate are low
Use Mobile operating system need not consider the influence of noise, thermal value etc. fully, what the failure rate of USB flash disk will be low for hard disk simultaneously is many.In energy-conservation, also increased the life-span of hard disk like this.
(3) easy to use
Mobile operating system is very easy to use, need only rely on a small and exquisite USB flash disk, need not to install, and the user just can start the operating system of oneself being familiar with and carry out all embedded operations on notebook computer.
(4) security
Because USB flash disk has the characteristic of plug and play, to pull up from notebook computer and take away as long as therefore will be integrated with the USB flash disk of Mobile operating system, all information that then reside in the internal memory all can and all empty along with the internal memory outage.Any virus on the USB flash disk or rogue program all can't cause to attack and destroy main frame, simultaneously, also can not leave over any record about USB flash disk in the main frame.
Embodiment
The present invention mainly can be made up of following two parts:
(1) BIOS of improved notebook computer (basic input output system, Basic Input or Output System (BIOS)) makes it can support USB (Universal Serial Bus, USB (universal serial bus)) to start.
Notebook computer in the market nearly all can not start by fine support USB, so must set about improving from BIOS.USB starts following four kinds of form: USB-HDD, USB-FDD, USB-ZIP, USB-CDROM, and the present invention can select for use.We can preferentially select the guidance mode of USB-HDD as Mobile operating system.
(2) Mobile operating system.
Smart little, safety, stable, beautiful interface, hardware requirement is low, and can self-defined property strong, software be abundant.Based on above-mentioned consideration, decision is adopted (SuSE) Linux OS and is improved.
Below be specific embodiments:
(1) BIOS (basic input output system, Basic Input or Output System (BIOS)) comprising:
A) power on selftest (POST, Power-On Self-Test), self-checking system equipment.
B) final stage of BIOS, read main boot record (MBR, main start record) to the particular memory address and redirect carry out.
C) mainboard can be with USB flash disk with the access of hard disk mode (to support what USB-HDD started).The flat storage of flash disk is modeled as common hard disk and conducts interviews with cylinder head sector (CHS, cylinder/magnetic head/sector) pattern.
(2) operating system
A) GRUB (a kind of Linux starts supervisory routine) guiding kernel
We adopt GRUB rather than the general LILO that adopts (another kind of Linux starts supervisory routine) to guide kernel.For visit and the startup of supporting USB, must carry out some changes and identification again in kernel.
B) boot kernel
Kernel is the basis of operating system, provides calculating the support and the system call interfaces of inboard installation.It can be before real subregion be by carry in start-up course, and the initrd.img file mount on ROOT (root) subregion point, as the virtual file system in the internal memory, and is carried out wherein startup script.Can load file system driver here generally speaking.In this stage, we have carried out modification, simplified and have recompilated kernel, start and reduce the size of whole kernel to support USB; Simultaneously, we also make amendment to initrd and wait for the initialized time of USB to provide.
C) startup of Init process
I, Init process are the parent processes of all processes, start prior to every other process.
Ii, we derive other processes and terminal shell process by the init process.
D) Shell process
Be the translation of user and operating system, it provides the command-line prompt symbol, and the user can operate at this.
(3) application program
