128MB Memory Upgrade Success
As some people may remember from way back when, I'd ordered some SDRAM chips to attempt to upgrade an Xbox to 128MB using the spare pads on the board. Rather than the 2 weeks quoted it took over 2 months to get the parts and then vacation/work got in the way. Finally I installed the new SRAMs into the Xbox last night.
The installation & operation of the devices presented no problems, just some careful cleanup of the pads and soldering of the new SDRAMs, it worked first time.
I now have a 128MB Xbox, I've verified the addional memory with some code I wrote, I can allocate/test 121MB of RAM, no problems, BUT, isnt there always a BUT:
1. Applications need to be compiled such that the 64MB memory limit flag needs to be NOT set.
2. You must have the debug BIOS loaded onto the board, the machine will work/boot OK but you wont see the additional 64MB
XMEM Application results
4627 Debug Bios - 121MB Available
Evox 2.5 - 58MB Available
So for the moment I cant play those super large Mame ROMS until I get the source and recompile. Unfortunatly my cable modem is down so I've not been able to DL & compile Mame with the 64MB flag cleared, I'll try that in the next couple of days if I get the chance.
Are there any budding Kernel hackers out there willing to help out with modifying the commercial bios such that it can support the 128MB of memory??
Also I think this mod would give good benefits to the Linux guys, so maybe they could add 128MB RAM support into their clearoom BIOS.
ja sitten vielä että se saadaan käyttöön:
xbe RAM Limit Remover, v.01
by: noptical
about :
This is just a small app coded to remove
the 64mb limit flag that most xbox
applications/games have set. Now, I know
hardly anyone is going to upgrade their
ram anytime soon, its good to have incase
you do, and mame wants to use it.
Instructions:
Run the program, browse for the main .xbe
and hit 'patch', its as simple as that.
Works on MAME and any other .xbe
