Hello,

There is any way to access memory in the first 1MB (conventional memory)
using DJGPP without needing to use selectors and/or _farpokex() routines?

I am working in some sound routines that require a DMA buffer, and I would
like to access directly that buffer. I was thinking in changing the limit
of the data selector (%ds) to 0xffffffff in that way I'd be able to access
the lower 1MB of memory directly. Is this possible? or I should not touch
the selectors %cs/%ds/%gs?

Thanks in Advance,
