I need to allocate a fixed and large memory block to use it as a DMA
buffer. In plain dos I use XMS to allocate and lock physical memory and
it works, but when I run the software under a Windows Dos Box the
operating system halts my program on the lock request !
I've heard about VDS services but I've not yet understand if it can
resolve the problem and how to use it exatly.
I appraciate any kind of help.

Thanks,

Simone Navari.
