Yes, I want to save data in a memory batterie backup like disk-on-chip for save a state of my machine but I need access in 32bits and in real time and multitasking and not by bios function who use real mode . So we can used disk-on-chip like a hard disk or like a memory with programming the window access at D000 to D1FF (8Ko) in dos segment. But I need too to access register on disk-on-chip to translate this window of 8Ko for access 16Mo of disk-on-chip. And I not found how access to this register on Internet. If you can help Me, Please Thanks.
