Hi all!
I have been playing with LinuxBIOS on motherboards with Intel's 440BX chipset. I have a whole bunch of them: a Microbits Epox EP-61 BXA-M, an MSI MS6120 (dual), an Intel development board and a custom designed BX board). I have managed to get most of the stuff up and running. Two things are missing though...
1. I can't manage to initiate more than 128 MB of SDRAM (ramtest fails). I've tried a lot of different types and brands of memories, standard DIMMs and SO-DIMMS, different sizes, etc. I'm thinking it has something to do with "double sided" memory (or dual "module banks" or whatever terminology you choose). Buffer strength settings maybe? But I've tried the same settings as the standard BIOS uses (which sets up the memory correctly btw) and still no go. Some obscure bit in some obscure register?
2. Dual CPU support on the MSI board.
My major concern is the memory support though.
I just thought that I'd throw out a question and see if somebody has been or is working with the same thing and has bumped into something similar. The archives tell me that there has been some fierce fighting with SDRAM issues earlier and I see why... This stuff is complicated.
I'm running a LinuxBIOS from CVS dated 2003-11-04.
