1. How to Use Dell DataSafe Local Backup to create system recovery mediaDell DataSafe Local Backup is a secure, simple, and highly reliable Local Backup and recovery solution that helps Dell Computer users avoid software faults and hard disk damages.The latest factory Dell Computer, such as Dell Alienware M11x, has been pre-installed with Dell DataSafe Local Backup.The following describes how to use a USB flash drive to create a system recovery medium
Following Dell's acquisition of alienware, HP also announced this year that it would acquire Voodoo PC, the biggest competitor of alienware, with the transaction amount kept confidential.
So far, Dell and HP have fully expanded their high-end product lines. However, for HP, this is the second merger, the first merger with Compaq has become one of the most famous failure cases in PC history.

But if there are too many parameters and the registers are not enough, then you have to put the extra parameters in the stack.
That is, you can use the stack to pass all the extra arguments that are not in place for the registers.3. An example of how the C language function call uses the stack
The function of the stack for the above explanation is somewhat abstract, and here's an example to explain it easily:
then test:

passes through. Check the R1 routing table, and the destination address 6.159.245.65 can match 0.0.0.0/0 in the routing table. Check the routing tables for R2, R3, and R4 to find the routing table entries that match the destination address.
Then, trace the path that the ICMP response response packet passed through. To complete this step, to explicitly respond to the source address of the packet, when the PC sends a ping, the response Reply packet's
Lab requirements:Set up the topology, import the pre-configuration, and troubleshoot the following errors.1. The link between R1 and SW1 cannot start;2. SW1 cannot start the trunk link between SW2 and SW3;3. Problems with etherchannel between SW2 and SW3;4. The HSRP between SW2 and SW3 cannot be automatically switched;5. R1 and R2 cannot dynamically obtain the address from DHCP server R3;6. R1 cannot access the server 5.5.5.5 on the ISP R5 without R2;7. When the Intranet accesses multiple server
I saw the following topic and asked which route was chosen when R4 arrived at R2. At that time, I was not sure. So I designed this topology to prove it and finally proved my conclusion. If the COST of R2.
In this topology, there is no difference between O routes and OIA routes at all, because OSPF is a link-State routing protocol, and R4 routes from two different links to R2 are OIA routes.
The topology is
passthrough area. Therefore, first check the RID of R2 and R4. Here, because I set the loopback port before configuring ospf, therefore, 2.2.2.2 and 4.4.4 are used.

abstract, and here is an example to illustrate briefly, it is easy to understand:Arm-inux-objdump–d u-boot > Dump_u-boot.txtYou can get the Dump_u-boot.txt file. The file is in, containing the executable assembly code of the program in U-boot, where we can see the source code of the C language function, which corresponds to those assembly code.The following is a compilation code of two functions,One is Clock_init,The other is not clock_init in the same C source file, and the other one is Copyco

library. The generated dynamic library name is libmyjni. so.
Local_ldlibs + =-llog specifies the library to be connected separately. We use the log library in the code, so this sentence is added here.
The include $ (build_shared_library) statement indicates that the library to be produced will be a shared library and a dynamic link library. To produce a static database, you can write: include $ (build_static_library ).
