configurationThere are two situations where the system cannot automatically complete the Configuration:(1) the BIOS cannot directly view the Linux Root partition;(2) the BIOS can only read and write the first 504 MB of the standard IDE hard disk.In this case, you must follow the most basic principle: to create a Linux partition with a smaller BIOS access, including the Kernel File, ing file, and chain loader, the root can be another independent partition. For other configuration details, we wil

1. class file structure any class file corresponds to the definition information for the only class or interface, but in turn, the class or interface is not necessarily defined in the file (for example, a class or interface can also be generated directly from the ClassLoader). The "Class" file does not necessarily exist on the diskA class file is a set of binary streams that are based on 8-bit bytes, with only two data types: unsigned number and tableUnsigned numbers are basic data types that re

location for the TFTP server.3) Copy the kernel/root file system files of the Linux installer to the root directory of the TFTP server. For each version of Red Hat Linux to be installed, you need to do this one time.Red Hat Linux The first installation CD/isolinux directory will contain the kernel/root file system files of the Linux installer. The following command copies these files to the root directory of the TFTP server and renames them according to the version. [[email prot

Analysis of mysql paging data loss1. Problematic code CleverCode finds that data is lost by page in mysql. As shown in the following code, the system_user table contains 4 million rows of data. In this case, all the userids in this table need to be obtained. In this case, only 20 thousand entries can be retrieved by page at a time. // System user table (4 million rows of data) $ systemUserTable = new systemUserTable (); // 20000 $ pageSize = 20000; for ($ curPage = 1 ;; $ curPage ++) {$ SQL = "s

into integers, we can use this experience of the cracker to do some hands and feet. For example, we split the user code into two integers U1, U2, the registration code is also split into two integers R1, R2, keygen for r1=u1+115,r2=u2+351, the verification function has two, wherein F1 is: [(R1-U1) (R2-U2) "2]1/2" (): ( R2-U2
