i know that i can use usb stick.... there is no problem with that....
also i have windows program to read ufs partition....
i thought that this fat32 partition is the best way.... but if it is not...
i installed solaris 10 on my laptop and there is one FAT32 partition of 21.6 Gb
in /etc/vfstab there is line for mounting this partition after boot
/dev/dsk/c1d0p4:c - /d pcfs - yes rw
