I am trying to access 0xD000 using a simple C program compiled with DJGPP and am getting Exiting due to signal SIGSEGV General Protection Fault at eip=0000362a When I access video memory at 0xB800, no problem. When I try 0xD0000, I either get the error, or if it works, I get data which is the same no matter what offset I use. The purpose is to access data being written by an ISA data aquisition card. Thanks for any help. WFR Operating system Win98
