😕 hi dear dosbox users!

after upgrading my ram to 6gbs i must hack my kernel for using of asfxload (32bit dma limit ?) :

1 and edit arch/x86/include/asm/dma.h, locate the line:
2
3#define MAX_DMA32_PFN ((4UL * 1024 * 1024 * 1024) >> PAGE_SHIFT)

and replace 4UL to 2UL

since that change i couldn't use my dosbox config with my old midi settings ...

for example:

1aplaymidi --port=128:0 /home/shorty/privateer_Gold/music/pirate.mid 

works ...
but changing the conf to:

1[midi]
2mpu401=intelligent
3device=alsa
4config=128:0

doesn't have any effects

see attached image *

any suggestions ??
