Here is my way:
The bootmanager file is located in /usr/src/release/sysinstall/bteasy17.uu
uudecode this file. You will get a file "bteasy17"
Now do the following (I hope you backed up your partition tables...):
dd if=bteasy17 of=/dev/wd0 bs=1 count=446
for each device you wish to boot from (/dev/wd0, /dev/wd1, /dev/sd0, etc.).
Beware:
- Don't use raw device names. They can't handle weird blocksizes.
- count=446 is extremely important. The partition table is 16 bytes
per entry plus 2 bytes magic number located at the end of the
sector. (446 = 512 - (4 * 16 + 2))
I've tried this multiple times with no problems. If you haven't
installed /usr/src/release, here is the uuencoded file:
begin 664 bteasy17
