No, I have only one disk inside my i386 box. So I need gpt inside a slice 
to boot from that disk.
Layout:

The data for partition 1 is:
sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD)
    start 63, size 1703457 (831 Meg), flag 80 (active)
        beg: cyl 0/ head 1/ sector 1;
        end: cyl 665/ head 15/ sector 63
The data for partition 2 is:
sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD)
    start 1703520, size 82155024 (40114 Meg), flag 0
        beg: cyl 666/ head 0/ sector 1;
        end: cyl 248/ head 15/ sector 63
The data for partition 3 is:
sysid 7 (0x07),(OS/2 HPFS, NTFS, QNX-2 (16 bit) or Advanced UNIX)
    start 83859300, size 41929650 (20473 Meg), flag 0
        beg: cyl 1023/ head 255/ sector 63;
        end: cyl 1023/ head 254/ sector 63
The data for partition 4 is:
sysid 165 (0xa5),(FreeBSD/NetBSD/386BSD)
    start 125788950, size 30507435 (14896 Meg), flag 0
        beg: cyl 1023/ head 255/ sector 63;
