The fact is that the preferred way to make the UDB self-booting is to put a
small (1440K) partition on your hard drive, set to type 4 (MSDOS) and copy
milo and linload to it using dd.
To make the partition DOS formatted is also important. So, how do you DOS
format a partition on an Alpha HD?
Easy! As I said, make a 1440K partition (fdisk, using the +1440K size option)
Then put Milo and linload.exe on a dos-formatted 3.5" floppy.
Stick the floppy in the (running) UDB.
If your new 1.44Mb partition is the 2nd physical partition:
do the following (VERY Carefully, a typo would be a Very Bad Thing!):
dd if=/dev/fd0 of=/dev/sda2 bs=10240
This will make a literal image of the floppy on the HD partition.
Obviously, if you partition is in a different p[lace you will need to adjust
the line above to suit. For the 3rd partition on a second SCSI HD it would be:
dd if=/dev/fd0 of=/dev/sdb3 bs=10240

There is a full description of how to set up the ARC console boot options to
use this, but I will skip this for brevity's sake. If you can't figure it
out, let me know and I will email the whole thing to you.
