This is basically what I have been using to format
the 8 M DiskOnChip (and put a bootable picoBSD on it),
I'm not sure its the best way, but works ok without
errors other than a disklabel warning about the
partition c use flag:
-----------------
dd if=/dev/zero of=/dev/fla0c count=100
dd if=/dev/zero of=/dev/fla0c count=100
disklabel -r -w /dev/fla0c doct
newfs /dev/fla0c
mount /dev/fla0c /mnt
mount /dev/fd0c /mnt1
cp /mnt1/kernel /mnt
umount /mnt
umount /mnt1
disklabel -r -B -b /boot/boot1 -s /boot/boot2 /dev/fla0c
-----------------
Using this disktab "doct" entry:
----------------
doct:ty=removable:dt=DOC2K:se#512:nt#1:rm#300:\
:ns#15920:nc#1:\
:pa#15920:oa#0:ba#4096:fa#512:\
:pc#15920:oc#0:bc#4096:fc#512:
---------------
I used "removable" so as not to write a DOS
partition MBR.
Of course, you might not need to copy the kernel
and bootstraps. I've found it useful on the 8M
DOC to keep a backup "kernel.old" and my
development picoBSD kernel that I copy over the
net. Convenient and works well.
