Yinchuan Commercial Bank Science and Technology Department
---- I work in a commercial bank, the operating environment of the unit is: the host uses IBM AIX, and the PC uses an Intel chip based microcomputer version UNIX. During the work, many key applications develop and testing need to be separated from the true operating environment. At the same time, developers must have a new environment for learning business and computer, at this time, there is a need to install UNIX on the developer's PC. However, Windows rich application software, powerful rapid development tool (RAD), and the need for small MIS and OA systems, making us inseparable from Windows.
---- For the need for work and learning, I will install the most popular commercial UNIX system SCO OpenServer 5.0.5 on Intel platform, and install it on a PC on a PC. And bear's paws.
---- The following is an example of installing Win 98, describing how to install SCO OpenServer on the basis of retaining Win 98.
---- First, draw a disk space for SCO OPENSERVER
---- I have a total of 6G (6150 MB), the main DOS partition 2G, extended DOS partition 4G, now built another partition in the extension partition, and 2G to SCO OpenServer. If you have a user's data on the extended partition, back up, or use a non-destructive partition tool to partition. Friends who steal your hard drive space can copy data to C disk :)
Run fdisk, select [4], show the current partition information:
Partition Status Type Volumn Label MBytes System Usage
C: 1 a Pri DOS WIN98 2000 FAT32 33%
2 EXT DOS 4150 67%
---- First, delete the DOS extension partition and its logic drive. After selecting [3] DELETE Partition or Logical Dos Drive, first delete the logical drive in the extended partition, select [3] delete logical dos drive (s) in the extended dos partition; then delete the extended partition, select [2] delete extended DOS partition.
---- Secondly, the SCO OpenServer is left to 2G disk space. This step is actually rebuilding a capacity reduction of 2G extension partition. After selecting [1] Creat DOS Partition or Logical Dos Drive, create an extension partition, select [2] Creat Extended Dos Partition, the extension partition created in the system prompt input, enter 2000MB, press ESC to return, will this All 2G space is given to a Logical Drive. Then show the current partition information:
Partition Status Type Volumn Label MBytes System Usage
C: 1 a Pri DOS WIN98 2000 FAT32 33%
2 EXT DOS 2000 Unknown 33%
---- Restart the machine and format the hard drive, and we have prepared the remaining 2G space for the installation of Sco OpenServer.
---- Second, install SCO OpenServer ---- put the boot disk marked with SCO OpenServer 5.0.5 boot disk into the A drive, install the disc to put into the CD-ROM, restart the machine, and start installing the SCO OpenServer. It is limited to the space, the specific installation step is slightly described, and only the part is introduced to the dual system startup.
---- In the Preparing Your Disk and Choosing Software interface, the hard disk settings are default:
---- Hard Disk Setup: UNIX ONLY: BAD TRACKING ON (All Hard Disk Space For Unix Using, and check the bad track)
---- In order to retain WIN 9X, press the space bar (
) Change, appears setting up your hard disks screen: Disk 0,6142MB. Partition & FileSystems: Use Whole Disk for UNIX (all hard disk space for unix)
Press Net
Use Whole Disk for UNIX
Customize
Interactive fdisk / Divvy
---- Options Use Whole Disk for UNIX will clear the existing partition of the hard disk to create a default partition that cannot be used only for UNIX. Customize allows new partition modifications. These two cannot save the original data and partition information.
---- Thus, select "Interactive FDisk / Divvy).
---- In the Starting Hard Disk Initialization ... interface, when the Initialization Selection screen appears, select 1 - Continue With Hard Disk Initialization (continued hard drive initialization), in subsequent hard disk parameters (such as cylindrical, magnetic head, each track fan) Area, etc.
1, Display Partition Table
2, Use Entire Disk for UNIX
3, Use Rest of Disk for UNIX
4, Crest UNIX Partition
5, ACTIVATE Partition
6, Delete Partition
7, CREAT Partition
---- First display the partition table information, but also compare the information of the DOS / WIN and UNIX FDISK display (later to use). Select 1, display:
Current Hard Disk Drive: / dev / rdisk / 0s0
Partition Status Type Start End Size
3 inactive dos (ext) 65025 130049 65025
4 Active Type 11 1 65024 65024
Total Disk Size: 199920 TRACKS
(256 reserved for masterboot and diagnostics)
---- From the display information, we should know:
---- 1, the measurement unit of SCO UNIX is the track, not the DOS / WIN sector (Sector), if it is a Win 9X to be left in the process of installing the SCO OpenServer, it should be magnetrically Calculate. ---- 2, the partition type displayed by SCO UNIX is different from DOS / WIN, so the respective FDISK tools should be used when partitioning.
---- 3, SCO UNIX partition number is different from the partition number under DOS / WIN, remember the partition number of the DOS / WIN C disk (here 4).
---- Then create a UNIX partition. Select 3- Use the remaining disk space to be unix, the system will display:
Current Hard Disk Drive: / dev / rdisk / 0s0
Partition Status Type Start End Size
1 inactive UNIX 130050 199664 69615
3 inactive dos (ext) 5025 130049 65025
4 Active Type 11 1 65024 65024
---- At this point, we have divided the entire hard drive into 3 partitions. Now, we set the UNIX partition to an active partition, which is important because the SCO OpenServer cannot be booted when DOS / WIN starts. If we use the boot disk, or run FDISK under DOS / WIN, set the meaning of the dual system. Select 5- Activate partition, enter SCO UNIX partition number "1". Finally, it is determined that the system displays the following information:
Partition Status Type Start End Size
1 Active UNIX 130050 199664 69615
3 inactive dos (ext) 65025 130049 65025
4 inactive Type 11 1 65024 65024
Press the "Q" button to exit and continue to install until the SCO OpenServer is installed.
----
Third, the test SCO Oenseerver and WIN 9X dual system switching
---- Restart the machine, when the boot prompt appears, you can choose to enter SCO UNIX or Win 9x. If you press
BOOTOS [? |
<2 HEX DIGITS> |
---- Where,
Boot
: bootos?
The system will display:
Partition status ID Type Start End Size
TRACK TRACK (TRACKS)
1 Active 63 UNIX 130050 199664 69615
2 00 None3 05 DOS_EXT 65025 130049 65025
4 0B UNKNOWN 1 65024 65024
---- From the above table, we can see that we will put the win 98 in the fourth partition, partition identification ID = 0b, so we can have two ways to guide Win 98 (this method does not change the actual activities) Partitioning, after restarting the machine from Win 98, returning to the SCO UNIX boot prompt state, this is the fundamental difference between the operation system / system with FDISK to change the active partition.
Bootos 4 or
bootos id = 0b
---- Note that do not use the "DOS" method to boot the partition created by Win 98, namely:
Boot
: DOS
---- Because SCO OpenServer creates a partition created by WIN 98 not to be identified, if you want to use a low version of FDISK, you can not recognize big hard drives, or reduce Windows performance. Therefore, use Win 9x's own partition tool to boot any bootable partition in SCO OpenServer.
---- When the familiar "window" is opened to us, the SCO OpenServer and WIN 9X dual system installation is also completed. From then on, we can install various development tools and database programs for Windows or SCO OpenServer. To learn and work.
