Hi folks

HELP ME!!! AST RAMPAGE/2 programming documentation needed!!!
...or AST technical support E-mail or fax/mail address needed

Anybody likes a company called AST???
This company is doomed.

I've got an AST RAMPAGE/2 ( well, it is old, really antique, but XT
holding it doesn't need better. ) memory card ( can be used to backfill
conventional memory or as expanded or extanded memory. )
And, possibly, I never will have anything from AST any more. At least
if I have to pay for AST's products.

Now this card has a wonderful(!?) setup program, so You needn't bother
setting proper switches and so on. It has a memory that holds the config
parameters.

But, a guy came, wondered: what this program's for?, and started to
study it. He set card's memory start address at 0K and somehow
made the card to think that it had only 64KB memory on board.

You think - no problem, just run the setup program again and everything
will be OK?

NO! This program is a simple .COM program. Even if it is started
by it's own BOOT program (ASTDOS,) it loads into segment higher than
0, of course. And it sets it's stack starting offset 0FFFFh - so it
can't be run on a machine that has only 64KB memory. I found one
place where it moved this value into SP register, but I couldn't find
the other - maybe there are more bugs.

Well, I need programming documentation on how to reset and write
this card's setup.

I know the following things:
 It's on board memory holds it's
 
    Base I/O address: it can be 208h, 218h, 258h, 268h, 2A8h, 2B8h, or 2E8h
    Amount of memory to backfill conventional memory.
    Memory Bank type: Bank 0 has 64K DRAMs, Bank 0 and 1 have 64KB DRAMs
                      or All banks have 256KB DRAMs
    Parity Error Checking: Enabled or Disabled
    Start Address of Expanded Memory
    
I think that the program outports something, inports something and then
writes the configuration into some area of memory ( for example at
segment 0D000h ). At least, I have no other ideas.

From the various docs, I've got, I read that Toshiba 1000 EMM Unit has
the same ports - but I have no further info about these ports. If
You happen to know these port's, maybe You can help me.


Thank You.
