Note: Because both Windows 98 systems and WINDOWS98+WINDOWSXP Dual systems can enter pure DOS mode, this is not the scope of this discussion, only the installation of the Windows XP desktop system.
Design ideas
Establish the Windows98 DOS mode (including only io.sys,msdos.sys,command.com three files) on the system disk C drive, and then install the WindowsXP system, resulting in a dual-system boot entry for WINDOWS98 and Windows XP. But Windows98 is not installed, just a simple DOS mode. Usually work into the windowsxp system, when encountering a system failure, then into the Windows98 dos mode, with Ghost software recovery system. In the event of serious problems, even if the system is not able to enter, then the super-aid disk to guide the system, to carry out related repair and maintenance operations.
Make Super First aid disk
Download the Super Rescue disk File Sos_disk.zip, then release the main file SOS4.exe and execute it and make the floppy disk as an emergency disk. In order to prevent some computers without floppy drive or floppy disk is not insured, you can make super First aid disk into first aid CD.
System Installation
1. To expedite the installation of Windows XP, you can pre-copy the installation files for Windows XP to your hard disk, such as the D drive.
2. Start the computer with the Super First aid, press the E key to exit its menu mode, enter the FORMATC:/S command at the DOS prompt, format the C disk of the system disk and transfer the DOS98 system. After the end of one of the files named deltree.com Copy to the C packing directory, and copy the Ghost software related programs to the Ghost Directory, for later use.
3. Run the windowsxp installation disk under the I386 folder Winnt.exe, the XP system DOS mode installation. After the installation is complete, do not rush to install the printer, scanner, video head, USB drive and other device drivers, so that the backup files will be made as small as possible.
System backup
After the installation is complete, shut down and restart the computer, select the second menu item "Microsoft Windows98", enter Windows98 's pure DOS mode, with deltree/ The y command format deletes the C-packing directory directly under the Pagefile.sys and Hiberfil.sys these two files (these two files are hidden properties and cannot be deleted with the Normal del command, so copy the deltree.com this DOS file to use. The purpose of this is to make the following backup files as small as possible to facilitate future burning to the CD to save, and then delete the deltree.com files with the del command. Finally run the Ghost software, make the partition into a gho image file, such as Dos98_winxp.gho, save to other partitions. To prevent an entire hard drive from going wrong, we can burn the Dos98_winxp.gho file to a disc and save it.
Emergency
Through the above steps, has been prepared for the future system of first aid work. Because the backup is the entire system partition, so if anything happens, as long as the software cloning system on everything intact, got the effect once and for all. If there is a hard disk partition table error or other catastrophic serious problem, then take out the first aid floppy disk or CD to boot the system, the corresponding first aid operation.
