I am doing cross developement under FreeBSD and DOS using djgpp (wonderful
product) and have come up against a problem I need some help with.

I can not find out how to allocate a buffer in the lower 1Mb so that I
can use int 13 functions 2 and 3 to do low level disk I/O.

I have every thing working except for this buffer, are there some magic
library calls to setup a bounce buffer in low memory so you can pass
a segmented address to the BIOS?

Help please!
