Are you sure you are using a Sun disklabel, not MSDOS partition table ?
If your disk comes from a PC box, try the 's' option in fdisk. It will build
a new sun disklabel with one swap and one ext2fs partition (and the whole disk
partition as number 3).
Note that the Sun disklabel is required by OpenPROM (the boot monitor) to boot
from HD.
My fdisk reports the following tags for partitions types:
# fdisk /dev/sda
Command (m for help): l
0 Empty 3 SunOS swap 6 SunOS stand 82 Linux swap
1 Boot 4 SunOS usr 7 SunOS var 83 Linux native
2 SunOS root 5 Whole disk 8 SunOS home
Command (m for help): p
Disk /dev/sda (Sun disk label): 17 heads, 80 sectors, 1965 cylinders
Units = cylinders of 1360 * 512 bytes
Device Flag Start End Blocks Id System
/dev/sda1 0 752 511360 83 Linux native
/dev/sda2 u 752 848 65280 82 Linux swap
/dev/sda3 0 1965 1336200 5 Whole disk
/dev/sda4 848 1965 759560 83 Linux native
Regards.
