win2000,red Hat Linux,sco UNIX Multi-operating system installation Instance

Changed a company, took a new machine, just installed the system, just want to install a number of operating system instances, the process written down, to many want to install the system and encounter many problems friends to do a reference.

I installed the new system for three days, to verify the various methods, the following will be the best way to write down. Before you do that, you should never use Microsoft Fdisk when partitioning, there are a lot of problems with the zoning, and then somehow there is an interval overlap between the SCO partition and the Redhat, which seems to be a different understanding of LBA, and my hard drive has 255 heads in SCO. In Linux, 240 heads are identified, but the total capacity is right. SCO's FDISK does not support the construction of various partitions, only DOS and SCO. If only SCO and win are installed, it is recommended to use SCO to partition DOS.

My machine is 10G hard drive, 64mram,reltek8139 network card, installed system is Win2000,sco openserver5.05, RedHat7.0, The goal is SCO with 1.5g,win 2G (c), Redhat 2G, the installation of the key is the partition, the steps are as follows:

1. With Redhat Guide, into the installation interface, all the way to the partition, select the manual partition, enter a character interface under the Fdisk, with the n command can create a new partition, with the M command can get command help.

2. The partition is built with three primary partitions first for SCO, the second for win, and the third for extended partitions. Select n when created will default to the Linux partition, but regardless, the prompt will be the start track number, then is +XXXXM, where xxxx is the capacity is how many m, such as the first partition for +1500m, the second partition for +2000m, the rest of the space to the third partition. When two partitions are built, the first partition type is changed to (GNU ...) with the T command, the second to 6 (FAT16), and the third to F (extended partition).

3. Then add the logical partition with the n command. Also with the n command, just the next choice when L (logical partition), because my hard drive is only 10G, so I only want to divide a win under the logical partition, so I built three logical partitions, respectively, for 2g,96m,4g. The default or Linux partition, or to use the T command to change them, respectively, to type (Linux), (Linux SWAP), 6 (WIN95 Ext ' d).

4. Use the W command to write the partition table after the Linux installer will let you continue, at this time do not continue, direct power to restart the machine on the line.

This partition is complete. The following is the installation system, as for the first outfit SCO or choose to install win is okay, as long as not repartition on the line. However, when the SCO is installed, the SCO partition should be set as the active partition, and the win partition will be activated when the win is installed. Because the LILO installed in the MBR to achieve multiple boot, so put Linux at the end of the installation is the most convenient.

It is necessary to set up SCO partitions as active partitions after the system is installed, because SCO partitions are not bootable when the SCO partition is activated. In addition, after installing Linux reboot you will see a graphical interface of Lilo, you want to go into the Linux modification/etc/lilo.conf, according to the DOS partition format for SCO add two line description, only the device named/dev/hda1,label for SCO. After the change, run a LILO command on the line, the restart you will see three prompts.
