Hi,
I am a novice in Unix installation.
Was experimenting with it.
During installation, i created 2 partitions ( what i am calling ).
One for the OS which was named SOLARIS & other was named PRI_DOS.
Now on completion of installation, where has my PRI_DOS portion gone.
How do i access it.
Thanks
Presumably you created 2 partitions using fdisk, the result of which is that you have divided the disk into two areas, one for unix and one for DOS/Windows.
In order to see anything in the DOS partition from Unix you will have to mount the partition.
And before you can mount the partition you will also have to format it (Boot from a DOS Diskette, or CD and format drive C:)
If on the other hand you created two filesystems using divvy, then maybe the installation process does not automatically complete the setup of non root filesystems. Run 'mkfs' and 'mount'.
It was created during installation via the GUI.
So what did it use.
How come now boot from a dos diskette?
My running one is c0d0s1 (for /) & c0d0s1 (for swap).
To mount that partition, it should know its device file.
How will i know that?
Thanks
Even after formatting how will i see it to mount it.
With Solaris you can mount a FAT partition using the msdos file system.
Try "man mount_msdos"
However that does not mean it was formatted as a FAT partition.
You will need to find the device name for that partition.
And how will i find the device name 
This may help...

Running either format or fdisk should be able to give you enough information to work it out.
thank's Mr.Porter for your info
