The question is:

The 8237A DMA chip on the PC:

on the AT and higher models, there are 8 dma channels.
I need to program channel 5, since I need to do 16 bit
dma transfers.  Anyways, to progam the target address
correctly, it needs a "page" address at port 0x8b.
What is this page address, and how can I do an address
translation to obtain this page number from
a data pointer.  The data pointer's memory space is allocated
using the "halloc()" under Microsoft C 5.1 which returns a
32 bit address.  And how can at obtain the base address from
this data pointer to send to port 0xc6.

i.e.
	unsigned short huge * dmaptr;
	dmatrp = (unsigned short huge *) halloc( 8196L, 2);

Thanks for the help,
