hello,

how can i have three OS in the same machine, for now i have two OS, win98 on the 1st partition and linux red hat on the second partition, can i have solaris on the third partition. and how?

thanks.

create a separate partition and specify the desired one upon installation

You can but it is tricky. Try installing Windows,Solaris,Linux in that order. When I did it, I installing linux second then solaris. Solaris's boot manager would not recognize linux. So I couldn't boot linux without using a boot diskette. But installing in the W/S/L order it worked just fine.

Be carefulwith Redhat Linux, unfortunately, both Solaris/x86 and linux swap partitions use the same ID, 0x82. So if you install Solaris on a drive with a Linux partition alredy on it, it will installon the Linux swap partition. You have a choice:
Solaris installation program which is called Webstart will probably ask you if you want to format what it thinks is your Linux swap partition. Be sure to not do this.
The old Redhat uses all Linux swap partitions on all drives. Since Solaris/x86 ises the same is, the installer overwrites it too. This is not a problem with older versions of RedHat Linux (as long as Linux and Solaris were on separate
drives). Installation of for example Red Hat Linux 6.1 can overwrite Solaris (the same occur with RedHat 7.3). If you have Solaris Intel on your machine, you will have problems with Red Hat Linux
Fix: Solaris partitions use the same type as Linux swap partitions.
The installer will use all found swap partitions. Currently, there are several possible workarounds to this problem. If
Solaris is on a separate drive from the drive you wish to install Red
Hat Linux on, please disconnect this drive.
The other workaround is to change the "Partition type" of the Solaris
partition. Before you install Red Hat Linux to another type, install Red Hat Linux, and then change the type back to another type. This can
be accomplished by going using expert mode and choosing fdisk over
disk druid.

# fdisk /dev/hda

Command (m for help): p

Disk /dev/hda: 255 heads, 63 sectors, 784 cylinders

After the install you can change the partition type to back 0x82 so
that Solaris will boot.

This "gotcha" was removed from the RedHat 6.2 list, so hopefully the
problem doesn't occur with newer versions of RedHat Linux.
