Abstract
The present invention provides a kind of method for showing CD Setup Type, for installing an operating system from CD-ROM drive on a computer, this method comprises: BIOS scans the computer peripheral equipment under open state, confirms that the computer is equipped with a CD-ROM drive；Judge in the CD-ROM drive with the presence or absence of a CD, and if it exists, then BIOS carries out reading data to the CD；Obtain the classification character string for describing the CD；By category character string display into BIOS setting menu, the Setup Type of the CD is confirmed according to category character string, confirms convenient for user and selects, in case the operating system of setup error, saves the time of user.
Description
Technical field
The present invention relates to a kind of methods of computer installation operating system, more particularly to a kind of be arranged in menu in BIOS to show
Show the method for the Setup Type of CD.
Background technique
BIOS(Basic Input Output System, basic input output system) technology is always computer software
It is contacted most closely in system with hardware, during PC starting, BIOS is responsible for initialization hardware, detects hardware function
Can, and the responsibility of guidance operating system, it can be seen that it is soft to be very important system for computer system by BIOS
Part, the computer of BIOS is not unable to run.
The installation of computer operating system (Operating System), there are many kinds of mounting means, such as from CD-ROM drive
Installation, from hard disk installation etc., for the user, selection is suitble to the mounting means of oneself, is arranged after menu just into BIOS
The installation of " foolproof " can be carried out, user can select after the computer for ensuring operating system to be installed has CD-ROM drive from light
Drive installation operating system, CD can be by there are two types of the Setup Types of imprinting, i.e. Windows system and linux system, generally
In the case of, disc manufacturer still can work as fixing disc in the Setup Type for indicating the CD in appearance of CD when leaving the factory
When having been placed in the CD-ROM drive of the computer of operating system to be installed, since current most of CD-ROM drive is in BIOS setting menu
Only show the title of the manufacturer of the CD of CD-ROM drive operation, this brings one from the user of CD-ROM drive installation operating system to selection
A little inconvenient, user generally requires to pop up CD-ROM drive, checks that the apparent mark of fixing disc just can know that the installation of installation hard disk
Type, furthermore, CD occurs normally wearing in use, and the Setup Type for causing manufacturer to indicate on CD can not
When seeing clearly, user needs for CD to be placed into CD-ROM drive, and opens computer and just can know that its Setup Type later, time-consuming to take
Power.
Therefore, based on the above issues, it would be highly desirable to a kind of method for inventing Setup Type that can be intuitively displayed CD.
Summary of the invention
For above situation, the purpose of the present invention, which essentially consists in, to be provided a kind of BIOS in computer and is executing power-on self-test
CD-ROM drive is differentiated and read during (Power On Self Test, abbreviation POST) function, and dish is set in BIOS
The method that the Setup Type of CD is shown in list, facilitates user to verify, and avoids the operating system of setup error.
In order to achieve the above objectives, the present invention provides a kind of method for showing CD Setup Type, and this method includes following step
It is rapid:
Under open state, BIOS scans the computer peripheral equipment, confirms that the computer is equipped with a CD-ROM drive；
Judge in the CD-ROM drive with the presence or absence of a CD, and if it exists, then BIOS carries out reading data to the CD；
Obtain the classification character string for describing the CD；
By category character string display into BIOS setting menu.
Particularly, reading data is carried out to the CD by the order read (10) of the BIOS ATAPI issued.
Particularly, the order read (10) of the ATAPI reads the volume identifier of master file in the CD, according to the volume identification
The data of corresponding byte area are accorded with, control ASCII character table obtains category character string, and category character string display is existed
BIOS is arranged in menu.
Compared to the prior art, the method for display CD Setup Type of the invention, starts from CD-ROM drive pacify on computers
When filling operating system, BIOS is during executing power-on self-test (Power On Self Test, abbreviation POST) function to light
Drive differentiated and read, and the Setup Type of operation CD intuitively show in BIOS setting menu, convenient for user's confirmation with
Selection, in case the operating system of setup error, saves the time of user.
[Detailed description of the invention]
Fig. 1 is that the invention shows the flow charts of the method for CD Setup Type；
Fig. 2 is that the invention shows the schematic diagrames of one embodiment of the method for CD Setup Type；
Fig. 3 is that the invention shows the schematic diagrames of one embodiment of the method for CD Setup Type.
[specific embodiment]
The method of display CD Setup Type of the invention, when starting installation operating system from CD-ROM drive on computers,
BIOS is differentiated and is read to CD-ROM drive during executing power-on self-test (Power On Self Test, abbreviation POST) function
It takes, the Setup Type of operation CD is intuitively shown in BIOS setting menu, confirms convenient for user and selects, in case installation is wrong
Operating system accidentally, referring to Fig. 1, the flow chart of the method for present invention installation operating system, as shown, this method includes
The following steps:
Step 11: booting prepares installation operating system；
Step 12:BIOS scans the computer peripheral equipment, judges whether be equipped with CD-ROM drive on the computer, if so, turning
To step 13, if it is not, then going to step 19；
Step 13:BIOS judges in the CD-ROM drive with the presence or absence of CD, and if it exists, goes to step 14, if it does not exist, then goes to
Step 19；
Step 14:BIOS carries out reading data to the CD；
Step 15: obtaining the classification character string for describing the CD；
Step 16: by category character string display into BIOS setting menu, user should according to the judgement of category character string
The Setup Type of CD；
Step 17: being determined whether that the operating system of imprinting on the CD is installed according to the Setup Type, if so, going to step
18, if it is not, going to step 19；
Step 18: operating system is installed according to prompt；
Step 19: exiting installation.
Fig. 2 and Fig. 3 are please referred to, is the schematic diagram of one embodiment of the invention, as shown, when BIOS determines the computer
On there are CD is placed in CD-ROM drive and the CD-ROM drive when, by BIOS issue ATAPI order read (10) CD is counted
Master file in the CD is read according to the order read (10) of reading, the ATAPI (At Attachment Packet Interface)
Volume identifier compare ASCII character table and obtain category character string according to the data of the corresponding byte area of the volume identifier,
And by category character string display in BIOS setting menu.For example, order read(10) read the optical disc storage data
The corresponding master file of sector16 (Primary Volume), the byte area of volume identifier (Volume Identifier)
(Byte Position) is 48 45 4C ... of 41-71(52), control ASCII character table show that its corresponding classification character string is
RHEL, related technical personnel can know that the operating system of the CD burning is linux system, to select according to their needs
Whether continue that operating system is installed.
A specific embodiment of the invention and embodiment are elaborated above in conjunction with attached drawing, but the present invention is not
It is limited to the above-described embodiment and examples, within the knowledge of those skilled in the art, this can also be not being departed from
It is made a variety of changes under the premise of inventive concept.
