i make little progress , so report it .
I install openbsd first in HDD.
then I install puppy linux .
1) use puppy' fdisk ,then
# fdisk /dev/sda
Device Boot Start End Blocks Id System
/dev/sda1 * 2048 10487807 5242880 83 Linux <-puppy
/dev/sda2 10487808 55830527 22671360 83 Linux <-ext2
/dev/sda3 55830528 78140159 11154816 a6 OpenBSD
i will want to use this ext2 from puppy and openbsd .
2)puppy's grub4dos controls ' boot proess openbsd or puppy '
menu.lst in sda1 is next.
title OpenBSD
chainloader (hd0,2)+1
rootnoverify (hd0,2)
boot
3)in openbsd
disklabel wd0 is next
# size offset fstype [fsize bsize cpg]
a: 19426368 56886176 4.2BSD 2048 16384 1 # /
b: 1055637 55830528 swap # none
c: 78140160 0 unused
namely , ext2 is not shown .
because i make ext2 after i install openbsd .
therefore i must 'disklabel -e'
details is next.
good Material is in openbsd's 'fdisk wd0'
#fdisk wd0
Disk: wd0 geometry: 4864/255/63 [78140160 Sectors]
Offset: 0 Signature: 0xAA55
Starting Ending LBA Info:

# # # #
i remember 10487808 & 45342720
then command
disklabel -e wd0
and then vi editor come up .
following openbsd FAQ , i add 'o: line' .
see below
# size offset fstype [fsize bsize cpg]
a: 19426368 56886176 4.2BSD 2048 16384 1 # /
b: 1055637 55830528 swap # none
c: 78140160 0 unused
o: 45342720 10487808 ext2fs
and at last
mount_ext2fs /dev/wd0o /EXT2
but this same method 'disklabel -e' donot go well in USB memory .
so i boot openbsd and puppy on USB by openbsd's grub .
