I have better version of programming MSR 20000018 around. I will try
to commit it next week. Does your board have SPD?

Put your VSAINIT.BIN+SYSMGR.BIN at the bottom of your flash (like what
we did with VGA BIOS). Point the address where vsmsetup want to look
for VSM to the bottom of your flash. It sould be able to find the
vsa. BTW, the code on the current SVN has some serious bug (forget to
call setup_realmode_idt() before vsmsetup()) so it will crash soon
after jump into VSA. I will commit it fix next week.
I think there are still one or two MSR we have to program and probably
we need big real mode instead of the real mode for VSA to work. I will
dig into it more with the JTAG debugger later.

Did you try to find on MSVC on ebay? BTW, by googleing the net
I found some VC/MASM are freely avaliable through MSDN. Do you
want to try it too?
