>Description:
my disk usage: ad0s1 NTFS (active), ad0s2 extended (NTFS)
ad2s1 NTFS, ad2s2 extended (NTFS), ad2s3 freebsd boot slice(active)
When I use ad2s3 boot with boot0 installed in ad0 option "update" enabled,
it will make ad0s1's flag 80->0, make it "not active".
Then next execution of boot0 won't find no active partion.
This situation won't happen if I boot from ad0s1 or I disable option "update".
>How-To-Repeat:
fdisk -u ad0
fdisk -u ad2
(make sure ad0s1 and ad2s3 is set active)
boot0cfg ad0
(then install boot0 on ad0, default option "update" is enabled)
reboot
boot from ad2s3
