SCO + Linux + Win2k multi-system boot Installation

For the sake of work, the leader assigned a new HP evopc machine with a random Turbo linux7.0 (Just Wanted To See Linux, haha), but the development environment is SCO unix5.0.6 + windows, I am familiar with installing Unix + windows dual operating systems, but I have never installed Unix + LINUX, and I have never tried any of my friends, I went online to find installation methods for Linux, windows, UNIX, windows, and other systems. After several days of searching for information, research, and testing, today, the SCO + Linux + Win2k system is successfully installed! Now I want to share my experience with you. please correct me!
　　
Currently, in addition to third-party software (such as SC), you only need to rely on Lilo and OS loader for multi-system boot installation. As I am not familiar with Linux, after several attempts, I failed to guide lilo in Unix + Linux + Win2k. (If you are familiar with Lilo, please tell me your experience. Thank you !) We had to apply OS loader.
　　
I. operating system loader multi-boot principle:
Through practical experience and understanding, I think the operating principle of OS loader is to convert the startup sector information from other operating systems into a file with a size of 512 bytes. When starting OS loader, it reads the file and starts the selected operating system. This can be achieved through the "DD" command of Linux and UNIX. OS loader does not occupy a single primary zone, and does not need to overwrite MBR at each startup. It is also convenient to add startup items. (That's why I gave up Lilo !!)
　　
Ii. Operating System installation sequence:
Based on your actual conditions, you need to allocate reserved partitions for each operating system. My machine is a 40 Gb hard disk, sco unix is 8.0 GB, Win2k is 25 GB, And Turbo Linux is 5 GB, (Apply the partition master to each system partition)
First, install sco unix 5.0. The installation method is normal without special processing.
Then there is the installation sequence of Win2k and tlinux. According to the characteristics of Linux, you must first install other operating systems, and finally install Linux. The installation of Win2k does not have any special processing.
Finally, it is the installation of Linux. here we need to note that during the installation, we should ask whether to write lilo into the MBR and write lilo in the boot partition, if you do not select MBR or your SCO, WIN won't be able to start. Because he has changed MBR, OS loader will not be able to function. Other normal installation methods.
　　
3. Read Linux boot zone records
The DD command is applied here. The following is an example:
Dd If =/dev/hda4 of =/mnt/Win-hda1 /. lnx BS = 512 COUNT = 1 (/dev/hda4 is the Linux Root partition). Store the system information of the Linux Root partition in the C root directory named 'linux. lnx '. Then, write the Linux. lnx file to your Win2k boot partition (usually C :) and restart and set the Win2k partition as the active partition.
　　
4. Modify the boot. ini file.
Go to Win2k and modify boot. ini as follows:
Add the following information under [Operating System:
"C:/ntboot. lnx =" Linux 7.0"
Save and restart the machine.
　　
At this time, the general success has been achieved. You can see if your Win2k startup is followed by a "Linux 7.0" prompt and select it to see if you have entered the familiar Linux interface, if you enter, it indicates that you have succeeded; otherwise, ntboot is yours. there is a problem with lnx, or your boot. the INI file is wrong !!!
　　
5. the Unix boot method is the same as that of Linux. I will not describe it here. Refer to the Linux method !!! This method can be used if you want to install other operating systems ~, If you are a fan of multiple operating systems, you can enjoy the installation !! FreeBSD + Linux + SCO Unix + Win2k + Win9x ...... as long as your hard disk is large enough, you can enjoy it !)
　　
After finishing SCO + Linux + Win2k, I was so excited that I wrote down my feelings and shared them with my friends. Some technical questions are not too detailed. If you have any questions, please contact us and correct the mistakes in this article !!! Thank you for your support !!
　　
6. Postscript:
　　
A. After several days of research, I am familiar with OS loader. It is indeed a good thing to do. I can make multiple systems without using third-party software. However, it is a pity that lilo is not too clear, and it is too troublesome to rewrite it, mainly for how to guide UNIX, if that friend uses lilo to make Unix + Linux + win, please let me know. Thank you !!
B. Why install sco unix first and then install other systems? I found that if SCO UNIX is used later, it may be a problem with the method of installation, (if you have any friends on UNIX and windows, please tell me how to install UNIX. Thank you !!) Therefore, install it first. If you have Linux + winnt + other systems, install linux later. Otherwise, your OS loader will not function. Haha, but you may also modify boot. ini as I said. I have not tried it !!!
C. Do not place lilo on MBR when you install lilo again !!!
D. I found that SCO UNIX does not support NTFS and cannot read and write the content of its NTFS partition. If that friend knows how to read and write, please let me know !!
E. your operating system must have Win NT. Otherwise, you will not be able to apply OS loader... only Lilo !!
