FIG. 2 is a flowchart illustrating an embodiment of a method of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1 and 2, the present invention comprises the steps of:
firstly, setting a flag bit.
Adding a response function of a designated key, such as F12, up and down keys and the like, in a BIOS code, detecting whether the set designated key is pressed at any time in the Boot process of a machine, executing the response function of the designated key when detecting that the designated key is pressed, writing a 0x60 register in a CMOS (chip for storing basic startup information of a computer) into a flag bit (such as AA), reading the value of the 0x60 register later, and responding according to the value.
Secondly, a driver of Realtek PXE IPV4 is added in a Source Code (resource library), and the driver needs to be loaded when the driver is started from the PXE subsequently.
And thirdly, designing a function for managing the starting item, and finishing the starting action from the PXE according to the flag bit in the first step.
Specifically, the step includes the following substeps:
step 1: in the function, a string pointer variable PXEBootOptionDescSring and HDDBootOptionDescSring are defined, and respectively assigned values are UEFI, PXE IP4 Realtek PCIe GBE Family Controller and Windows book Manager, the string is a description of the startup item, and the startup item can be found through the description later.
Step 2: and starting a system variable service, calling a GetEfiVariable () function to find a system variable 'BootOrder' to acquire a variable value (BootOrder: the face contains all starting items in the current system) and the byte number (BootOrderSize) of the variable value. According to the number of bytes of the variable, the number (BootOrderCount) of all the startup items in the current system can be calculated.
And step 3: define pointer variable BootOrder2, call pBS- > AllocatePool to BootOrder2 allocate the same size memory as BootOrder. And establishing a for loop by using the BootOrderCount calculated in the step 2, and writing the values in BootOrder into the BootOrder2 one by one, so as to facilitate the starting sequence of the starting items in BootOrder in the subsequent operation.
And 4, step 4: finding out Windows Booot Manager in BootOrder2 and using the Windows Booot Manager as a first boot item, establishing a for loop by using the BootOrderCount calculated in step 2, obtaining variable values (NvramOption2) of each boot item one by one, obtaining description (Option description) and path DevicePath of the boot item according to the variable values, then using the values as judgment conditions to find out the Windows Booot Manager position in the current BootOrder2, and assigning the boot item of BootOrder2 to BootOrder [0] if BootOrder2[ i ], wherein i is not less than 0 and not more than BootOrder Count, and the boot item is the BootOrder Manager, thus finishing the action of finding out Windows Booger and using the boot Manager as the first boot item, which ensures that the computer can load OS when other operations are not known to be executed in the boot process.
And 5: the flag bit is used to determine whether to use PXE as the first starting item. Firstly, judging whether the flag bit of the CMOS 0x60 is AA, if not, loading the OS by taking Windows boot Mananger as a first starting item according to the step 4. If the flag bit is AA, similar to step 5, a for loop is established, the description (OptionDescription) and the path DevicePath of each boot entry are obtained, the PXE in BootOrder is found and then used as the first boot entry, and the PXE driver is loaded to complete the action of starting from the PXE.
The invention increases the response of the designated key, utilizes the designated key to control whether to start from the PXE, replaces a plurality of operation steps in the prior art, is convenient and fast to operate and greatly improves the working efficiency. If the computer is not started from the PXE, the invention can ensure that the computer can correctly load the Windows Boot Manager, and has strong practicability.
The above-described embodiments are intended to be illustrative, and not restrictive, of the invention, and all changes that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
