Hopefully I'm posting this to the right place. Please send replies to me via mail, as I do not normally read these newsgroups. My address is aas@sat.datapoint.com. What is the easiest way for a protected-mode (386 enhanced) Windows 3.0 application to access a memory mapped device? How do you make an entry in your virtual machine's Local Descriptor Table (LDT) to reference a given physical memory location? Can this be done without writing a Virtual Device Driver? Thanks in advance for any information, Adrienne
