In atricle by Steven M. Schultz:
Kernels are a special case of overlaid program (user
mode programs
may be overlaid too but have less restrictive size rules). The
BASE segment (non-overlaid portion) may be up to 56kb (57344) bytes
in size. Each of the 15 (maximum) overlays (OV1 thru OV15) may be
up to 8kb (8192) bytes.
Firstly, thanks to Steven for a great email. Yes, add it to the docs NOW
before you forget! Secondly, most of what Steven said also applies to
2.9BSD, because it also uses overlays. However, v6 and v7 do not use
overlays, so you can't use these techniques with them.
Ciao,
Warren

You're quite welcome.
I should have had another sentence in the paragraph above: the
kernel overlays must be between 48kb and 56kb. 56 is the max,
but the kernel also has a minimum BASE size of 48kb (but this is
all too easy to achieve ;-)).

Hi Robin -

Hi Steve,
The most recent version (Rev 280) will build GENERIC fine but previous ones
didn't. The makefile required tweaking. Maybe all he needs is the last few
patches.
That is most likely what happened - I'd made some changes to the
kernel just before creating the Rev 277 images (which is what was
entered into Warren's archive) and didn't double check that the
GENERIC kernel would build correctly.
I don't believe I've mentioned it on this mailing list yet but the
complete collection of 2.11BSD patches/updates are available via
anonymous FTP to the host FTP.IIPO.GTEGSC.COM in the directory
/pub/2.11BSD. There have been 4 updates released recently: 278 thru
281.
Cheers.
Steven

Hi,
Well I havn't tried your mix but a DEQNA fits ok. What you need to do is do
a size on the unix file that has been generated and workout which overlays
are blowing the loader. If you add the size of the base code and any overlay
together they can't be more than 64k. Then just move things between overlays
and base until they work. You don't have to delete the modules that you don't
want, they don't add anything.
Good luck, it can be tricky but it does work after you have pushed a few modules
around.
Robin
