- !!! Attention all Mega Midget Racer owners with 32bit DRAM !!!
- --------------------------------------------------------------
-
- Have you ever wanted your 32bit RAM to auto-config so that the entire
- system is running out of 32bit RAM? I'm not talking about moving kickstart
- into 32bit RAM. I'm talking about having graphics.library, intuition.library,
- drive buffers, etc., etc., etc. in 32bit RAM? (i.e. the 32bit RAM is added
- before most system start-up routines are executed.)
-
- Well, I wrote a program that accomplishes such. Overall system performance
- is increased slightly - over and above that of moving kickstart into 32bit.
- BUT, if you have a NON-DMA hard drive controller, there's a big performance
- increase - since the buffers are now in 32bit RAM. (I have no idea how DMA
- controllers will react to this - probably very poorly.)
-
- The only thing that doesn't get moved - YET - is exec. :-( Also, it only works
- under 2.04 with 32bit DRAM. And I've only been able to test it with the 8meg
- board. (It doesn't "pseudo-auto-config" any SRAM since I don't have any to
- test it with.)
-
- Now, is there any type of demand for such a program? (I have no idea how many
- MMR's are out there *WITH* 32bit DRAM.)
