I succeded finally to go further with installation, through interactive text desktop way, which is much faster than the default interactive one, but Solaris (10.5) only "sees" the Windows C partition and the extended one.
As i don`t want to get rid of Windows, or make the rest of the drive only for Solaris, pls advice what to do next - i have "prepared" (right now is FAT32, but before was unformatted and still "invisible" as "right place to install there" for Solaris) on extended volume 10 GB for it... just how can i point it to install there? What FS is to be seen as "OK"?Or, what to do?
In addition, i have only 1 hard disk, so that`s it, those 10 GB is the best i can do for Solaris.
