"To manually boot a disk..."

[ntohsepuasmch@centurytel.net (Theusch Family)]

Hiya kids.

I am attempting to make a sort of "network drive" for an Apple IIe.
It involves using a serial null-modem connection to simulate the
actions of what the RWTS IOB does with disks, except it retrievs disk
info from a pc running "server" software.  I was hoping to be able to
"boot" a "file server" "disk", therefore completely eliminating the
need for a disk drive, except for my network booter program.

012- What does it mean to "Boot" a disk?

     BOOT comes from the idea of 'pulling yourself up by your
bootstraps'.  The Apple II disk controller ROM has just enough smarts
to load-in DOS's Bootstrap Loader from Track 0, Sector 0 (it comes in
at address $800 ...).

     The Loader loads in a still smarter, bigger routine from several
sectors of Track 0. This routine is the one which loads in the rest of
DOS, moves it to the proper place in memory, and ends up going to
DOS's Cold Start routine. Finally, the hello program is loaded and
executed.

What exactly would I have to read and execute from a DOS 3.3 disk
(ProDos disk, any disk?) to start up the "Bootstrap Loader"?
Eventually I would have to modify everything to be redirected through
the null-modem ( !! ) but that is a different task.  If somebody could
just explain the booting process in hazy detail, I will be satisfied
for awhile.

Would I just sorta read in Track 0, sector 0, to address $800, and JMP
to that?

Thanx.
