Hi again,

This is a valid model of partitioning on SPARC?

~ # fdisk /dev/sda

Command (m for help): p

Disk /dev/sda (Sun disk label): 255 heads, 63 sectors, 17840 cylinders
Units = cylinders of 16065 * 512 bytes

   Device Flag    Start       End    Blocks   Id  System
/dev/sda1             0        12     96390    1  Boot
/dev/sda2            12     17080 137098710   83  Linux native
/dev/sda3             0     17840 143299800    5  Whole disk
/dev/sda4         17080     17840   6104700   82  Linux swap

Tks,
